Server

How many online users can the server support? How about product performance?

ConnectEase is a platform that offers efficient and reliable communication cloud services, supports products with hundreds of millions of users, and its system architecture can ensure flexible scalability and support dynamic expansion of access products.

Is our data safe on ConnectEase?

The data transmission and storage on ConnectEase is encrypted by private protocols, and the stored data is safe and reliable.

Considering that all our users are in foreign countries, what about access speed?

Foreign users can access services through our cloud host in AWS, and ConnectEase has deployed servers in many places abroad, so the nearest server can be selected to ensure access speed.

What is the relationship between the login token and my account password? how do I maintain the token?

The token is a credential for the authentication of the product applications and ConnectEase, while the account password is categorized into the third-party product application account system, between which the mapping relationship should be maintained by the application background; it is recommended to create an account and token for the user through a background interface when the user first accesses ConnectEase and associate the account and token in the application account system; the token is necessary for subsequent access to ConnectEase, and the token can be updated through the server interface of ConnectEase, for which the update policy can be decided by the application according to its own security policy.

Why can't I create an account through the client SDK instead of the server?

ConnectEase account system and application account system are bound together, and account creation in the application server can be effectively controlled. Any client of the application is at the risk of being cracked. If a ConnectEase account can be directly created through the client, your application account may be hacked. Business competitors may provide similar client interfaces, so that you can save a few lines of code in development, but your applications may be exposed to security risk.

Can the ConnectEase account be deleted? can the accid be the account of my business system?

The account of ConnectEase cannot be deleted. However, if you do not want to use the account, you may disable the account via the server interface. The developer may directly use the business system uid or account as ConnectEase accid for registration, but not recommended. The developer is recommended to use random strings and other strings that are not strongly associated with the application business as ConnectEase accid when creating a ConnectEase account, and then maintain the association between the business uid and the ConnectEase accid in the application server.

• Advantages:
• This may effectively protect the account system of the business side, and will not directly disclose the user account in the service of ConnectEase. Despite the safe and reliable protective measures taken for the data stored by the business side in ConnectEase, as a responsible service provider, we recommend to properly protect your data.
• If the business side wishes to delete a ConnectEase account, it is only required to unbind the relationship. If the business side wishes to reset the status of an account in ConnectEase, it is only required to unbind it, create and rebind the ConnectEase accid.

I have millions of stock user accounts, can you support batch account import?

The charging method of ConnectEase depends on the active users of the application, and it is recommended to follow the principle of "create on demand" for any application account access. A considerable proportion of zombie users or inactive users exist in your millions of accounts, and it is unnecessary to directly import all the users when migrating to ConnectEase. You can check whether the accid of the user's ConnectEase is created when the user triggers ConnectEase IM for the first time. If not created, an account will be created automatically in the background for login. In this way, your users can only create a ConnectEase account when necessary, and the users created in ConnectEase are all active users. Although this may reduce the number of your registered users in ConnectEase, it will also save costs paid to ConnectEase, and we still recommend the best practice to you as a responsible service provider.

Will the account registered through the server interface appear at my management background?

The account registered via the server interface will not appear at the management background.

• Reasons:
• The user list provided by the management background is not exhaustive. It is designed to provide convenience for the developer to rapidly complete client integration in the absence of server development in the access process. Users may rapidly create test users at the management background and log in to the client for test;
• Users created via interface will not be displayed at the management background to protect users' privacy and account security, thus preventing any improper disabling or other misoperations against users.

What is the md5 in the server message example?

This md5 is calculated by Md5 encryption algorithm based on the file content such as image and voice.

Access

How to access your platform? What is the general process of integrating ConnectEase?

You can access our platform only in four steps: step 1, register as ConnectEase developer. Step 2, create application. Step 3, integrate user system. Step 4, download and integrate SDK. You can refer to details in beginner access.

Do I have to use your server and database when developing IM using ConnectEase?

Unnecessary. Integration of ConnectEase: the ConnectEase cloud service is connected by integrating SDK at the client. The business logic and actual deployment of the application itself are still exactly the same as traditional development, and are maintained and deployed by the development team itself.

Where do I get AppKey from?

After registering and activating ConnectEase developer account, log in to the ConnectEase management background, create your app and get it on the "APP Key" page. Details are given in APPKey information.

How to create a user?

Test applications may create test users by logging in to the management background after the developer account is registered, or creating an account interface according to the server file in the development manual. Online applications can only create a user through the interface. Refer to the interface description for details.

What is multi-terminal mutual removal mechanism? When do I receive kick notice?

ConnectEase supports the most basic three mutual removal policies:

• Only one terminal of each platform can be online, and the platform consists of desktop (PC+WEB) and mobile (IOS+AOS);
• At most one client can be online at the same time (i.e. all ends are mutually exclusive).
• All the terminals can be online at the same time, but the maximum number of clients online at the same time cannot exceed 10. If excess, the earliest client will be kicked-out; the kicked-out client will receive a removal notice when the client triggers the mutual removal policy; to implement your own mutual kick policy, ConnectEase also provides an interface to actively kick out other online clients, which can be invoked by the application on demand, and the kicked-out client will also receive a notice at this time.

Why can't I create an account through the client SDK instead of the server?

ConnectEase account system and application account system are bound together, and account creation in the application server can be effectively controlled. Any client of the application is at the risk of being cracked. If a ConnectEase account can be directly created through the client, your application account may be hacked (Business competitors may provide similar client interfaces, so that you can save a few lines of code in development, but your applications may be exposed to security risk);

Data encryption, compression, etc.

PC: All text data communicated with the server and locally cached is compressed and encrypted. iOS: Only the table name (i.e. session name) of local chat data is encrypted, and picture messages are compressed to jpeg by default, with a compression parameter of 0.5 (freely configured by the upper layer). Video and audio are not compressed. The text data communicated with the server is compressed and encrypted. Web: Only text data is stored, no image, audio or video will be stored (so no data compression). Data is not encrypted, the browser itself has same-origin restrictions (security restrictions). Android: Android local chat data is not encrypted, and picture messages (pictures are uploaded like files) and video and audio are not compressed. The text data communicated with the server is compressed and encrypted. Each terminal does not limit the frequency of sending and receiving messages

How to integrate ConnectEase account system ?

Your user can register in your server at the client. This account is saved at your server, and then our server interface is invoked to register ConnectEase IM account and generate ConnectEase IM account and token. At this time, the user registered account and ConnectEase IM account will be bound, and the user will first log in to his registered account, get the bound ConnectEase IM account and token from your client and log in to the ConnectEase through the client. Here are two account systems

Demo

What can I do if Demo login failed?

The demo account is created by logging into the ConnectEase management background on the account management page of the ConnectEase Demo app. Please confirm that the demo account has been created correctly and that the correct token corresponding to the demo account is used when logging in on the demo client. If the developer compiles and packages their own codes, please confirm that the appkey configuration in the source packages has not been updated.

How to quickly develop my own application based on Demo source code？

• Log in to the ConnectEase management background to create your own application;

• Modify the AppKey configuration in the demo source code to the application AppKey created in step 1;

• Create a development/debugging account on the user management page of the application in step 1;

• Modify the demo source code according to demo guide document, ConnectEase development manual and application requirements.

• The friendship and user information are maintained by the application server itself.

  Note: Some developers can't log in correctly after updating the appkey configuration of the demo source code. Please confirm the following:

• The account and token are created in the updated appkey application;

• Confirm that the account and token used during login are correct.

If I changed demo appkey, how do I do when 302 password error is displayed during login with a registered account?

Log in to the DEMO by password for MD5 operation to simulate the process of getting a token from the APP server. For APPs registered by users themselves, this process is not needed, and the account password created by ConnectEase management background can be directly passed in. However, it is not recommended to directly expose the account password and other information to the ConnectEase service (although we provide safe and reliable protection measures for the data stored by the business side in ConnectEase and no risk of leakage exists, you are still recommended to protect your data appropriately as a responsible service provider), and it is recommended to bind ConnectEase users by unassociated account and Token, and add the process of getting ConnectEase account and Token from the application server during login.

The downloaded demo cannot be connected to the server, is a specific port configured?

Check if your network firewall allows access to port 8080 of the external server.

appkeyi changed in demo. Why can’t I register an account or get chat room list?

The demo appkey is used for demo, and the demo server is used for registration. After changing the appkey, the demo server cannot recognize new appkey, so the registration fails. (The ConnectEase account is registered and created through the server interface). Similarly, the chat room list is made available from the demo server.

Why can’t I download the excel on andriod Only android demo sending and receiving are demonstrated.

The interface is the same as the image download interface, and downlodAttachment is invoked, because no system file selector is available. You should choose where to save the file. In iOS demo, you can view and download the files, such as excel and word files.

iOS SDK

iOS SDK is compatible with ATS

Foreword

With the introduction of Apple's new policy on 2017.1.1, App will no longer allow the schemes of directly using Allow Arbitrary Loads = YES to avoid all domain names. Based on this, ConnectEase iOS SDK made some compatible adjustment.

What we've done

ConnectEase SDK mainly provides IM related features, and its internal implementation is based on TCP independent encryption protocol, and no adaptation is needed. To ensure the integrity of the whole IM feature, ConnectEase also has a built-in file transfer feature, including but not limited to message attachment, user avatar, team owner avatar, and other information. In older versions, these files are uploaded to the server as a HTTP request. This is clearly against Apple's rules. So in the new version, we have upgraded the file transfer, and all uploaded and downloaded files are transferred by HTTPS.

What should upper-level developer do?

After the above update, the upper-level developer can directly use our new iOS SDK, without making any ATS related settings in plist.

However, ConnectEase is a multi-terminal product. Although iOS is fully compatible with HTTPS, the other terminals are still not fully compatible with HTTPS. HTTP is still applicable to the files URL received from these terminals (certainly, there's the problem with old versions). Therefore, the upper layer developer should solve the compatibility problem for certain special scenarios.

File information is used in the following attachments of ConnectEase:

• Picture message attachment
• Voice message attachment
• Audio message attachment
• File message attachment
• Custom message attachment
• Avatar
• Team avatar
• User avatar in the chat

iOS SDK for the first four message attachments are already fully compatible: the file attachments URL sent from the other terminals are automatically converted from HTTP to HTTPS.

As for custom messages, since the entire class structure is determined by the upper layer, iOS SDK does not support intelligent and automatic conversion of URL message attachments, and the upper layer users shall complete corresponding processing. The interface is defined in id to convert ConnectEase connection from HTTP to HTTPS : convertHttpToHttps. If this file should be downloaded, conversion shall be made first. Refer to burn-after-reading message download in demo. Note that if a custom message should be downloaded by SDK managed attachment, then HTTP is converted to HTTPS over NIMCsutomAttachment protocolattachmentURLStringForDownloading.

For the latter three avatars, if ConnectEase avatar is directly used for upper-layer development, no processing is required. If you are using the file address of your own server, then you should set enableHttpsForInfoas NO in NIMSDKCofig.

The minimum requirement for iOS NIM SDK integration?

The SDK should at least support 7.0, and Xcode 8.0 or later versions are required.

Is iOS Demo compilation failed?

• Confirm that the file NIM.xcworkspace is opened;

• Confirm that Xcode is 8.0 or later versions.

How about integration failure?

We recommend you to carry out inspection in the following order:

• View official documentation
• Compare related feature DEMOs
• Consult the technical staff

What if the SDK is too large?

Since the NIM SDK is a static library, and for the convenience of the developer, we have combined the static libraries of the armv7 i386 x86_64 arm64 platform into one Fat Library, forming a relatively large SDK. However, the ipa file size will be increased according to invoked features during actual compilation, actually by about 2-3M.

• Tip: The developer can use the lipo -info command to check if a static library is a fat library.

How about login failure?

Login interface callback method contains error messages. Please check [error code]. Common error codes are as follows:

• 408, namely NIMRemoteErrorCodeTimeoutError, request timed out. This error is generally caused by poor client network conditions. Please check the network conditions.
• 415, namely NIMRemoteErrorCodeConnectionError, server connection error;
• 302 , namely NIMRemoteErrorCodeInvalidPass, authentication failed. User name and password are inconsistent. Please check if there is any discrepancy between the user name/password typed and server settings.

How to quickly implement a chat window interface for iOS?

The amount of code required to implement a chat window from scratch is around 5,000 lines and a variety of bugs are fixed. It is recommended to directly use the UI library NIMKit from ConnectEase or use some open source solutions such as JSQMessage.

Why can't I receive message and notification after APP is switched to background?

Due to restrictions by iOS system, most APPs do not support running in the background, so the APPs will be suspended a few seconds to minutes after the APPs go into the background and cannot receive any message. In this case, all messages and notifications are pushed (APNS) to the user. Only after the user has received the push message and opened the APP, the SDK will automatically reconnect to the server and pull the offline messages and notifications.

Why can't I receive push message after APP is switched to background?

Apple push (APNS) does not take effect automatically when the NIM SDK is connected. To put it into effect, the developer should complete the following configurations:

• For the certificate required to produce the APNS, please refer to push certificate p12 documentation;
• Upload the certificate to the NIM management background and set the certificate name;
• Set the certificate name in APP;
• Register APNS at client, and transfer the value to the SDK when the APNS token is obtained.

Considering IOS SDK cannot be put on shelf due to large cache, can't I synchronize icloud?

Our SDK directory is not backed up by default. "You can go read the attributes of the two subdirectories Users and Global under $Documents/NIMSDK. Both have the file attributes of NSURLIsExcludedFromBackupKey, and are YES"

Android SDK

Must I put SDK initialization in onCreate of Application?

Yes. Typically, ConnectEase service will work in the push process. When the push process automatically starts from the background, there is no chance to initialize the SDK other than onCreate of the application. Definitely, if you put the service and the main UI process of ConnectEase together and do not require automatic login in the background, then you can enable initialization if appropriate.

How to mention someone?

• When sending a team message to mention someone, you can send it together with the list of mentioned accounts through the extended field; when the team members receive a team message, check whether they are in the list of mentioned accounts of the extended field. If Yes, the interface will give an alert of being mentioned;

• In addition, the recent sessions list also provides an extended tag, so that the developer can give an alert of being mentioned in the recent sessions list: when listening for an update of the recent contacts, the developer can give an alert of being mentioned in the recent sessions lists according to the recent message; when listening for an update of the recent contacts, the developer can query this message based on the ID of the newest message, and check if the extended field contains the list of mentioned accounts; if your account is included, you can make a mark on the extended tag; if you receive a new message (view the message before entering the chat interface), an alert of being mentioned in the recent sessions list shall be maintained. The alert of being mentioned will be given at the interface by referring to the extended tag.

How to reset the unread count?

• The unread messages of the contact are stored in the RecentContact class, and the unread count is managed by the SDK. No interface is provided to set the unread count;
• The basis for updating the unread count of the SDK is controlled by the setChattingAccount interface, which sets the object that is currently chatting. When this interface is invoked, the unread count of this chat object is set to 0, and its unread count will not increase if a new message from this contact arrives later. If a new message is not received from the current chat object, the SDK will automatically accumulate the unread count of the message source and notify the UI through the observeRecentContact observer interface.
• After invoking setChattingAccount, the SDK will assume that the setting object is the chat object and the unread count of this chat object will be 0. Therefore, when the user exits the session with this chat object, the chat object should be set to null again; (MsgService#setChattingAccount(MSG_CHATTING_ ACCOUNT_NONE, SessionTypeEnum.None)).

Why is my receiver not triggered after sending a custom notification?

    Please check whether
        <permission android:name="com.netease.nim.demo.permission.RECEIVE_MSG" android:protectionLevel="signature"/>
    and
        <uses-permission android:name="com.netease.nim.demo.permission.RECEIVE_MSG"/>
    Are added to the manifest file. The first one is to declare the permission and the second one is to declare that you want to use the permission, both of them are indispensable.

If message is unsuccessfully sent, how do I send this messge?

Send Message API: sendMessage(IMMessage msg, boolean resend); look carefully at the parameters, the boolean indicates message resending.

How do I determine the attachment sending status?

def not downloaded, just like failure, can be re-downloaded by downloadAttachment.

Can we use our own V7 package?

If our uikit is used, then the v7 package should be our version based on v7 19. If other versions (21/23) are used, a conflict may occur.

PC SDK

The minimum requirement for NIM Windows client SDK integration?

Windows client SDK is developed by VC2010, and the APP developer can dynamically load the SDK DLL, only if the released application is provided with msvcr100.dll and msvcp100.dll libraries. Therefore, there is no The minimum requirement for SDK integration, and the later VC versions will yield better results.

How to use a custom user data directory at Windows client?

The Windows client SDK itself provides user-defined data directory file paths, and the user should transfer the absolute path only when initializing the SDK; however, it should be noted that Windows 7 has strong permission control on the directory under the system disk, and it is likely that improper use leads to that user data cannot be read and written properly, so it is recommended that APP developer shall try to put the user data directory in the system local application data directory.

%LOCALAPPDATA%，
     WIN7 or later versions in system disk C:\Users\<user name>\AppData\Local，
     WIN XP/2000 C:\Documents and Settings\ <user name>\Local Settings\Application Data

This is done by passing in the directory name when initializing the SDK, and the SDK will create the corresponding file directory in the system local application data directory as the user data directory.

Which development languages are supported by Windows client SDK?

The Windows client SDK is open to the C interface, so common desktop development languages can be invoked, including C++, Java, VB, C#, Javascript and Python.

Unity SDK

What are the SDK Unity integration requirements?

Unity SDK and Demo are developed using Unity 5.3.1f1, and SDK can be integrated for this version and later versions.

What are SDK considerations?

The interfaces provided by the SDK are all asynchronous, and receive execution results through callback function. UI objects cannot be directly manipulated in the callback functions, but the results can be saved to update the game in the update function, or updated by other means. (The Loom class is provided in the demo to implement this feature.)

Can I debug SDK features during development?

ConnectEase Unity SDK implements basic communication depending on unmanaged codes, such as threads and network transmission. Problems with the Visual Studio Tools for Unity plug-in may lead to problems for the debugging codes. Refer to Troubleshooting and known issues

What are considerations for user login?

Only one account can be logged in. When logging in to other accounts, you must invoke the Logout function to log out the logged-in account first. If the Login interface is invoked multiple times, it will return kNIMLocalResAPIErrorEntered (20002) error, indicating that an account is being logged in. This is especially important when running games in Unity Editor, because Editor hosts a game in the same process. If you don't log out after running, another login will fail, and abnormal closing of threads started by the SDK will lead to that the Unity process cannot be normally closed. The Logout function is also asynchronous and the login interface must be invoked again after function execution has completed, namely the callback function is triggered.

Why cannot I execute callback functions of some interfaces after logging out and re-logging in?

When Logout is invoked, the underlying layer will first release the existing objects and then recreate them, so that the callback functions originally set on these objects are invalid and NIM.ClientAPI.RegisterSdkCallbacks should be invoked for another registration.

Web SDK

Is SDK compatible with old browser?

Currently, the SDK is compatible with IE8, and xhr-polling is used by IE8/IE9 to simulate long connections. WebSocket is used by other advanced browsers to establish long connection.

Is file upload compatible with old browser?

Currently, file uploads are compatible to IE8, and Iframe is used by IE8/IE9 to upload files. FormData is used by other advanced browsers to upload files.

Message

What messages are available? Is my own custom message supported?

ConnectEase initially supports common messages such as text, image, voice, video and location; for special needs, ConnectEase also provides custom messages, and custom messages can be used to achieve "read-after-burning" and other special messages.

What is the proportio between the thumbnail image and the original image sent by ConnectEase?

iOS: equal scaling of length and width, short edge scaling down to 150 on 2x display screen. Except iPhone plus series, iPhone4 and later versions are Retina on 2x screen, and plus series is 3x screen, that is to say, 225 for plus. iPhone 3gs and previous versions are 1x screen (until 75); Android: set a width in SDKOption#thumbSize, scaled equally. Generally, it refers to the width of the bubble of the image in the session window. You can also simply set it to half the screen width.

Can’t I receive messages from specific user or specific team

ConnectEase offers a blacklist based on your own friendship system.

An interface is also provided to update team message notifications . Details are given in the following documents: iOS message notification iOS team message notification

How long can I save historical record? How to get it?

The SDK will keep a local message history and offer a deletion and query interface, which is managed by the application itself. ConnectEase server provides the service of saving server history. This service occupies server storage resources and is a paid service that can be kept for up to 3 years. The server saves the history and also provides a query interface for use.

How does the management background send system messages to the user (or team)?

• A ConnectEase account is specifically created to send system messages;
• The interface is invoked to send normal/transmission message among the server message service interfaces, as detailed in interface description;
• Normal messages are common session messages that appear in the chat window, while transmission messages are application notifications (not required when a chat window appears). For the concept of transmission messages and the difference between the two, please refer to the chapter "Message Service" on the Server page of the Development Manual.

Is message length limited?

The message length of ConnectEase is limited to 5,000 characters.

What is the format of the audio file of the voice message and the video file of the video message from ConnectEase?

For voice and video messages, ConnectEase only supports file upload and message delivery, so all formats are available for audio. However, it is recommended to use the interface provided by ConnectEase for audio recording and play, because we provide HD voice recording methods, and the voice intelligibility is far higher than similar products. aac is a configured format for audio recording through the interface provided by ConnectEase.

How does NetEase Yun send an emoji?

The emojis in the chat actually are strings, which can be mapped by certain rules to display different images. For details, please refer to the implementation in the ConnectEase DEMO.

Can I only send text messages, not images and files?

Yes. This feature can be limited in the upper level to only send text messages, not image and file messages, and we provide a platform to remove any undesired features on demand.

Demo message uninstallation and reinstallation

1. A new device ID is generated for each uninstallation and reinstallation. After login, 100 sessions (100 messages sent and received per session) are roamed by the server.

2. App is not uninstalled from Android, and the data is cleared. However, a device ID is also regenerated. After login, roaming messages will also be received. For example, I logged in on an android device and sent "hello world". Then, I cleaned up app data and then logged in the app again, and the server will roam "hello world".

3. Roaming is managed by the server, and has no relationship with the client, but the client should enable data clearing from the system. Roaming is also enabled, that is, the SDK db is cleared, and it will roam over.

Or another situation: the user can set application management, and clean up the data generated by app. For login later, roaming will be also available. Roaming will be available only whenever a new device ID is generated.

Session list and roaming message details

Each client gets the list of recent sessions from local data. There is no upper limit to the number of lists available. Local data will be affected in the following cases:

1. The application has executed the interface to delete a session.

2. A new phone is used, or local data is cleared from ConnectEase.

3. If roaming is enabled, the server will synchronize the roaming data to the local database.

Roaming details

Roaming messages are now configured online with 100 sessions, 100 recent messages per session in the last 7 days. Other details:

1. Web advanced browser (that supports local database), and local historical data is available like other clients.

Team

What is the maximum number of team members and teams?

Each user can create 50 normal teams with up to 200 members by default, and 50 advanced teams with up to 200 members. We can support the extension of the number of teams and team size for special needs.

After I have successfully created a team and specify the members at the server interface, why do I only see the team owner in querying the team members?

The parameter "magree" of the team creation interface indicates "whether team members' consent is required". If you have created a team and only see yourself, please check this parameter first. If this option has been selected, the invitee will appear in the list of team members only after consent.

Does the SDK provide an interface to set the team capacity?

Can I set the management background? SDK does not have this interface. The management background cannot be set until now, and maybe provided later.

What are the differences between an advanced team and a normal team?

• NIM SDK offers the team chat features in two forms, i.e. normal team and advanced team. The advanced team has more operation permissions, and the interfaces are kept consistent under common operations. It is recommended to choose a team type for APP development. In principle, normal team and advanced team are not interchangeable, since their types have been confirmed once created;
• Without operation authority, a normal team applies to the scenario of quickly creating multi-person session. Each normal team can only have one manager. The manager can add or remove team members and normal team members can only invite other users to the team. New members may be added without their consent;
• Advanced team is subject to more limitations on permission which is granted to the owner, manager and, team members.

Can the advanced team owner successfully execute quitTeam? Is a team dismissed?

The advanced team owner cannot successfully operate quitTeam, and will not dismiss a team. To leave a team, the team owner should transfer the team owner privileges to a designated member of the team or directly dismiss the team.

If I want to delete my recent contact list after I quit the team what should I do?

There are two interfaces to delete recent contact records, deleteRecentContact and deleteRecentContact2, the first of which takes the RecentContact as a parameter and does not trigger observer notifications after an invocation, and is suitable for invocation in the recent contact list. The second interface takes account and sessionType as parameters, and triggers observeRecentContactDeleted notification of the MsgServiceObserver after successfully deleted. Therefore, you can invoke the second interface and add a deletion event observer to the recent contacts list.

Chat room

Is there an interface to get the list of chat room managers?

There is currently no directly accessible interface, but it is recommended to retrieve membership information by memberType after getting chat room member information.

What is the common difference between messaging in chat rooms and IM?

The chat room messaging interface is the same as the normal messaging interface. The session type needs to be set as chat room to send a message. The session id is the chat room id. However, for chat room messages, the SDK will merge the incoming messages. While for other IM messages, only offline messages and roaming messages are from the server in bulk.

How do I get the number of members online in the chat room?

Users can get the number of members online in the chat room by getting the chat room information after entering the chat room. When a member enters or exits a chat room, the ConnectEase server will send an entry/exit notification message to the client, and then the client will add or subtract the online number in the chat room based on the notification message in real time. For other content in the chat room, please refer to ConnectEase Chat Room FAQ
