问题描述

关于

我正在与Laravel学习Vue.js.目前，正在练习在2个用户之间发送实时文本消息.

I am learning Vue.js with Laravel. Presently, practicing on sending real time text messages between 2 users.

下面的代码将消息发送给另一个用户

var url = "http://localhost:6001/apps/My_appId/events?auth_key=My_Key";

var socketId = Echo.socketId();
var request = {
    "channel": "private-Send-Message-Channel.2",
    "name": "MessengerEvent",
    "data": {
        "msg": message
    },
    "socket_id": socketId
};
axios.post(url, 
    JSON.stringify(request))
        .then((response) => {
        //Success callback
    }
);

接收消息

window.Echo.private('Send-Message-Channel.2')   
    .on('MessengerEvent', (e) => {
      //Receive the message
    }
);

问题:请假，加入，键入，总用户数是否有回调?

Question: Is there any callback for on leave, on join , on typing, total users?

推荐答案

您需要使用presence频道.如上所述，这些渠道也是私有的:

You need to user a presence channel. As described these channels are also private:

所有在线状态频道也是私人频道

All presence channels are also private channels

您可以使用.join设置状态频道.

You can set up a presence channel by using .join.

Echo.join(`chat.${roomId}`)
    .here((users) => {
        //
    })
    .joining((user) => {
        console.log(user.name);
    })
    .leaving((user) => {
        console.log(user.name);
    });

您可以访问要查找的回调.

There you have access to the callback that you are looking for.
