发送私聊消息

    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
    let textMessage = im.createTextMessage({
        text: 'Hello, GoEasyIM', //消息内容
        to: {
            type: GoEasy.IM_SCENE.PRIVATE,   //私聊还是群聊，群聊为GoEasy.IM_SCENE.GROUP
            id: 'user002', //接收方用户id
            data: {"avatar": "/www/xxx.png", "nickname": "Neo"} //接收方用户扩展数据, 任意格式的字符串或者对象，用于更新会话列表conversation.data
        }
    });
    
    //发送消息
    im.sendMessage({
        message: textMessage,
        onSuccess: function () { //发送成功
            console.log("Private message sent successfully.", textMessage);
        },
        onFailed: function (error) { //发送失败
            console.log('Failed to send private message，code:' + error.code + ' ,error ' + error.content);
        }
    });

接收私聊消息

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 onPrivateMessageReceived = function (message) {
    //文字消息
    // {
    //     "messageId": "8f0e27a0c7e111eab347b726da4416bd",
    //     "timestamp": 1594958217087,
    //     "type": "text",
    //     "senderId": "3bb179af-bcc5-4fe0-9dac-c05688484649",
    //     "payload": {
    //         "text": "Hello, GoEasyIM"
    //     },
    //     "receiverId": "fdee46b0-4b01-4590-bdba-6586d7617f95"
    // }
    console.log("received private message:" + JSON.stringify(message));
};
//监听和接收单聊消息
im.on(GoEasy.IM_EVENT.PRIVATE_MESSAGE_RECEIVED, onPrivateMessageReceived);

取消监听私聊消息

    im.off(GoEasy.IM_EVENT.PRIVATE_MESSAGE_RECEIVED, onPrivateMessageReceived);
