Chat room

Update time: 2024/03/14 18:45:31

Please refer to Integration mode to download and introduce SDK file.

Overview

  • Creating or dismissing a chat room with SDK API is now unavailable.
  • If a user enters a chat room, new connection must be created. If the user leaves or is removed from the chat room, connection will be disabled. If the user is disconnected from a chat room, automatic re-connection will be executed. Developers need to monitor connection status of a chat room to make correct API action.
  • The number of online members in a chat room is not limited.
  • Users can enter a chat room manually and can not invitations.
  • A user is allowed to enter multiple chat rooms and create multiple connections.
  • After disconnecting from a chat room, the user will no longer receive messages related to the chat room from the server.
  • Before any operation, a user needs to first enter the chat room. That is to say, the user must first initialize chat room and get the callback onconnect.
  • When a user enters a chat room, the user will not receive push notification history from the chat room. If the message history is required, he can call The API Query messages.

Get the server address of a chat room

Before initializing a chat room, you need to first get the server address of chat room by the following two methods.

  • If developers have NIM instances, the server address of chat room can be acquired from IM connection, with the sample code shown as below:
javascriptnim.getChatroomAddress({
  chatroomId: 'chatroomId',
  done: getChatroomAddressDone
});
function getChatroomAddressDone(error, obj) {
  console.log('get chat room address' + (!error?'succeeded':'failed’), error, obj);
}

Initialize a chat room

  • Before initializing chat room, you need to Get the server address of a chat room.
  • The API is set as singleton mode. For the same account, it always returns the same instance. For example, only the first invocation will initialize one instance.
  • The initialized instance will be returned in subsequent invocation of The API. The API Update chat room configurations is also invoked to update input configurations.
  • When The API is invoked subsequently, if connection is disabled, automatic connection will be enabled.
  • If disconnection occurs, the SDK will re-connect automatically.
  • If you get the callback onconnect, it means that you have entered a chat room successfully and now can execute other operations.
  • Anonymous login
    • The SDK allows users to visit chat room as guests, i.e. the parameter isAnonymous is set to "true" to realize.
    • For anonymous login for the first time (creating instance), it is not necessary to fill in the parameter "account" , but it requires to get the parameter generated by the SDK from chat room instance after login.
    • Anonymous login requires a nickname of a user. For non-anonymous login, the nickname is optional. We recommend filling in photo profiles.
    • In order to avoid creating new instance for a chat room, we recommend inputting the previous account with the parameter at the time of update or second getInstance if they need to update chat room configurations (anonymous mode).

Sample codes

javascript// Note that you may need to call The API by SDK.Chatroom.getInstance if you are introducing different SDK files

  // Send messages after successful connection
  var msg = chatroom.sendText({
    text: 'hello',
    done: function sendChatroomMsgDone (msgObj) {
    }
  })
}

    // Wrong account or password, please jump to the login page with an error message
    case 302:
      break;
    // Removed, please jump to the login page after giving an error tip
    case 'kicked':
      break;
    default:
      break;
    }
  }
}
function onChatroomError(error, obj) {

Types of chat room notification messages

Send chat room messages

There are APIs as below:

Send text messages

javascriptvar msg = chatroom.sendText({
  text: 'hello',
  done: sendChatroomMsgDone
});
console.log('sending chat room text message, id=' + msg.idClient);
function sendChatroomMsgDone(error, msg) {
  console.log('send chat room' + msg.type + 'message' + (!error?'succeeded':'failed’) + ', id=' + msg.idClient, error, msg);
}

Preview files

  • Developers can preview the file. Several scenes are available:
    • A file is input with the parameter fileInput to select DOM node or node ID.
    • Blob object is input with the parameter blob.
    • The data URL that contains MIME type and base64 is input with the parameter dataURL. This method requires that explorer supports window.Blob.
  • SDK will upload the file to file server and then transfer acquired file object to developers in the callback done. There are several file objects as below:
  • After getting the file object, developers can invoke "Send chat room file message" to send file message.
  • File size limit is 100M max.
    • The advanced explorer will check file size before the file is uploaded.
    • IE8/IE9 will check file size after the file is uploaded (v5.0.0 and below support IE8).
javascriptchatroom.previewFile({
  type: 'image',
  fileInput: fileInput,
  uploadprogress: function(obj) {
    console.log('total file size: ' + obj.total + 'bytes');
    console.log('uploaded size: ' + obj.loaded + 'bytes');
    console.log('upload progress: ' + obj.percentage);
    console.log('upload progress text: ' + obj.percentageText);
  },
  done: function(error, file) {
    console.log('upload image' + (!error?'succeeded:'failed'));
    // show file to the user
    if (!error) {
      var msg = chatroom.sendFile({
        scene: 'p2p',
        to: 'account',
        file: file,
        done: sendChatroomMsgDone
      });
      console.log('sending chat room image message, id=' + msg.idClient);
    }
  }
});

Send file messages

  • File message is one type of Chat room messages.
  • Developers can send file message.
    • Several scenes are available:
      • A file is input with the parameter fileInput to select DOM node or node ID.
      • Blob object is input with the parameter blob.
      • The data URL that contains MIME type and base64 is input with the parameter dataURL. This method requires that explorer supports window.Blob.
    • SDK will upload the file to file server and then transfer acquired file object to users in the callback uploaddone, and edit it into file message to send out.
  • Developers can also Preview chat room file to get file object and then invoke The API to send file message.
  • If the file message is sent, SDK generated idClient will be input in the callback beforesend. If you preview the file and then send it out, The API will return idClient.
  • The parameter type designates file type to be sent, including image, audio file, video and common file, with corresponding value 'image', 'audio', 'video' and 'file' respectively. If it is not input, the value is 'file' by default.
  • The difference among image, audio file, video and common file is that detailed file information is different. For detailed fields, see:
  • File size limit is 100M max.
    • The advanced explorer will check file size before the file is uploaded.
    • IE8/IE9 will check file size after the file is uploaded (v5.0.0 and below support IE8).
javascriptchatroom.sendFile({
  type: 'image',
  fileInput: fileInput,
  uploadprogress: function(obj) {
    console.log('total file size: ' + obj.total + 'bytes');
    console.log('uploaded size: ' + obj.loaded + 'bytes');
    console.log('upload progress: ' + obj.percentage);
    console.log('upload progress text: ' + obj.percentageText);
  },
  uploaddone: function(error, file) {
    console.log('upload' + (!error?'succeeded':'failed’), error, file);
  },
  beforesend: function(msg) {
    console.log('sending chat room image message, id=' + msg.idClient);
  },
  done: sendChatroomMsgDone
});

Send location messages

javascriptvar msg = chatroom.sendGeo({
  scene: 'p2p',
  to: 'account',
  geo: {
    lng: '116.3833',
    lat: '39.9167',
    title: 'Beijing'
  },
  done: sendChatroomMsgDone
});
console.log('sending chat room geo message, id=' + msg.idClient);

Send tip messages

  • Tip message is one type of Chat room messages.
  • The tip message is used to remind status in session, for example, welcome message in session, or prompt message when the session contains sensitive.

  scene: 'p2p',
  to: 'account',
  tip: 'tip content',
  done: sendChatroomMsgDone
});
console.log('sending chat room tip message, id=' + msg.idClient);

Send custom messages

javascriptvar value = Math.ceil(Math.random()*3);
var content = {
  type: 1,
  data: {
    value: value
  }
};
var msg = chatroom.sendCustomMsg({
  content: JSON.stringify(content),
  done: sendChatroomMsgDone
});
console.log('sending chat room custom message, id=' + msg.idClient);

Send configuration options of chat room messages

  • The above APIs for sending message can be configured with extra options to meet developers' custom demands for server.

    • custom: Extension field.
      • We recommend creating user profile in JSON format. If it is not JSON format, other clients may abandon the information, although Web client will receive it ordinaryly.
    • skipHistory: It determines whether to skip cloud storage. This message will not be included when message history is acquired.
    • yidunEnable: It designates whether it is necessary to use custom anti-spam field, i.e. antiSpamContent. The default value is false which means that it is not required.
    • antiSpamUsingYidun: It determines whether GuideEase anti-spam is enabled for a single message. false means that GuideEase anti-spam is disabled when GuideEase is enabled.
    • antiSpamContent: When yidunEnable is enabled, developers customize anti-spam field with json format {"type": 1, "data": "custom content"}. Notes: type: 1. Text; 2. Image, 3. Video; data content: text or image address or video address.
  • We take an example of sending file message here. The API for sending other messages is similar.

javascriptvar msg = chatroom.sendText({
  text: 'hello',
  custom: '{}',
  done: sendChatroomMsgDone
});
console.log('sending chat room text message, id=' + msg.idClient);

Get the message history

  • timetag: Several data before corresponding time point of timetag is acquired.
  • If it is not timetag, it will be current server time by default.
  • limit: If it is empty, the value is 100 by default.
  • reverse: The default false means to query message history forward from timetag; true means to query message history backward from timetag.
  • msgTypes is character string or array. You can select to acquire message type of history. If it is empty, type is not distinguished and all messages are acquired.
    • text: Filter text message
