触发套接字断开事件时如何调用laravel事件或函数

Question

我正在使用 Laravel 5.2，我想要的是从套接字事件断开调用自定义函数来更新我的表 playsessions 中的记录。

流程：

1. 当用户进入频道部分，我通过 AJAX 发送用户的设备信息，例如：ip、devide、浏览器、socket id 等...以便在数据库中创建记录.

2. 但如果用户断开连接，我想更新发送套接字 id 的记录。

实际上，我做了第一步，但我不知道如何做第二步。

查看 Channel.blade.php

var socket = io.connect('http://localhost:3000');

socket.on('connect', function() {
    var socket_id = socket.io.engine.id;

    $.ajax({
        type: 'POST',
        url: "{{ route('play_session.store') }}",
        data: {
            ip: "{{ $play_session_data['ip'] }}",
            device: "{{ $play_session_data['device'] }}",
            platform: "{{ $play_session_data['platform'] }}",
            browser: "{{ $play_session_data['browser'] }}",
            session_id: "{{ $play_session_data['session_id'] }}",
            user_id: "{{ $play_session_data['user_id'] }}",
            channel_id: "{{ $play_session_data['channel_id'] }}",
            socket_id: socket_id
        },
        success: function() {
            console.log('session created');
        }
    });
});

Socket.js

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var redis = require('redis');

server.listen(3000);

io.on('connection', function (socket) {
    console.log("new client connected " + socket.id);

    socket.on('disconnect', function() {
        console.log('client disconnected');

        // I want to call here a event of laravel or function sending the socket.id to update a record in database 
    });
});

或者当用户与 laravel 服务器断开连接时，最好的方法是什么。

更新：

我现在在事件断开中使用 AJAX 但不起作用：

查看 Channel.blade.php

var socket = io.connect('http://localhost:3000');

socket.on('connect', function() {
    var socket_id = socket.io.engine.id;

    $.ajax({
        type: 'POST',
        url: "{{ route('play_session.store') }}",
        data: {
            ip: "{{ $play_session_data['ip'] }}",
            device: "{{ $play_session_data['device'] }}",
            platform: "{{ $play_session_data['platform'] }}",
            browser: "{{ $play_session_data['browser'] }}",
            session_id: "{{ $play_session_data['session_id'] }}",
            user_id: "{{ $play_session_data['user_id'] }}",
            channel_id: "{{ $play_session_data['channel_id'] }}",
            socket_id: socket_id
        },
        success: function() {
            console.log('session created');
        }
    });

    socket.on('disconnected', function() {
        $.ajax({
            type: 'POST',
            url: "{{ route('play_session.close') }}",
            data: {
                socket_id: socket_id
            },
            success: function() {
                console.log('session closed');
            }
        });
    });
});

谢谢。

您可以发送包含所需数据的 AJAX 请求并从那里触发事件。
