发送群聊消息 - GoEasy IM

前置条件

发送群消息

    var im = goeasy.im;   

    //创建消息, 内容最长不超过3K,可以发送字符串,对象和json格式字符串
    var textMessage = im.createTextMessage({
        text:'Hello, GoEasyIM', //消息内容
        to : {
            type : GoEasy.IM_SCENE.GROUP,   //私聊还是群聊,私聊为GoEasy.IM_SCENE.PRIVATE
            id : 'group001',  //群id
            data : {"avatar":"/www/xxx.png","nickname":"区块链交流群"} //群信息, 任意格式的字符串或者对象,用于更新会话列表中的群信息conversation.data
        }
    });

   //发送消息
   im.sendMessage({
      message:textMessage,
      onSuccess: function (message) {  //发送成功
          console.log("Group message sent successfully.", message);
      },
      onFailed: function (error) { //发送失败
          console.log("Failed to send group message, code:"+error.code+ ",error:"+error.content);
      }
    });

接收群聊消息

对于收到且已读的消息,需要标记为已读状态,否则会话列表里的数字始终保持原来数字,并且在下次连接GoEasy时,GoEasy会重复下发之前未标记的消息。


    var onGroupMessageReceived = function(message) {
        //群聊消息message示例
        // {
        //     "messageId": "a5f705e0c7e111eab347b726da4416bd",
        //     "type": "text",
        //     "timestamp": 1594958255483,
        //     "senderId": "3bb179af-bcc5-4fe0-9dac-c05688484649",
        //     "senderData": {"avatar":"/www/xxx.png","nickname":"Neo"}, //发送者Data,仅限群聊消息
        //     "payload": {
        //         "text": "Hello, GoEasyIM"
        //     },
        //     "groupId": "group-a42b-47b2-bb1e-15e0f5f9a19a"
        // }
        console.log("received group message:" + JSON.stringify(message));
    };

    //接收群消息
    im.on(GoEasy.IM_EVENT.GROUP_MESSAGE_RECEIVED, onGroupMessageReceived);


    //订阅群消息
    var groupIds = ["group001"];
    im.subscribeGroup({
        groupIds:groupIds,
        onSuccess: function () {  //订阅成功
           console.log("Group message subscribe successfully.");
        },
        onFailed: function (error) { //订阅失败
           console.log("Failed to subscribe group message, code:" + error.code + " content:" + error.content);
        }
    });

取消订阅群聊消息


    //取消订阅群聊消息
    im.unsubscribeGroup({
        groupId:"group001",
        onSuccess: function (message) {  //取消成功
           console.log("Group message unsubscribe successfully.");
        },
        onFailed: function (error) { //取消失败
           console.log("Failed to unsubscribe group message, code:" + error.code + " content:" + error.content);
        }
    });
