【中文标题】laravel-echo-server 用户未加入，未订阅套接字服务器

【英文标题】：laravel-echo-server user not joining, not subscribed to the socket server

【发布时间】：2019-05-29 09:12:25

【问题描述】：

Laravel echo server is started 事件被广播，但用户无法加入频道，因此无法收听该事件。

1. ExampleEvent file:
class ExampleEvent implements ShouldBroadcast

    use Dispatchable, InteractsWithSockets, SerializesModels;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct()
    
        //
    

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    
        return new Channel('test-event');
    

    public function broadcastWith()
    
        return [
            'data' => 'key'
        ];
    


2. Laravel-echo-server.json file

    "authHost": "http://localhost",
    "authEndpoint": "/broadcasting/auth",
    "clients": [],
    "database": "redis",
    "databaseConfig": 
        "redis":  ,
        "sqlite": 
            "databasePath": "/database/laravel-echo-server.sqlite"
        
    ,
    "devMode": true,
    "host": null,
    "port": "6001",
    "protocol": "http",
    "socketio": ,
    "sslCertPath": "",
    "sslKeyPath": "",
    "sslCertChainPath": "",
    "sslPassphrase": "",
    "subscribers": 
        "http": true,
        "redis": true
    ,
    "apiOriginAllow": 
        "allowCors": false,
        "allowOrigin": "",
        "allowMethods": "",
        "allowHeaders": ""
    


3. boostrap.js file laravel echo section

import Echo from 'laravel-echo'

window.io = require('socket.io-client');

window.Echo = new Echo(
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001'
);

window.Echo.channel('test-event')
    .listen('ExampleEvent', (e) => 
        console.log(e);
    );

4.Channels.php file
<?php

Broadcast::channel('App.User.id', function ($user, $id) 
    return (int) $user->id === (int) $id;
);

Broadcast::channel('test-event', function ($user, $id) 
    return true;
);

5.env file redis section

BROADCAST_DRIVER=redis
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

Output: When i open http://127.0.0.1:8000/test-broadcast and on other browser http://127.0.0.1:8000/ not shown that user joined the channel etc and event details is not listen on other browser. Also not getting any error on command line or console log.

【参考方案1】：

我遇到了同样的问题。

试试这个版本"socket.io-client": "2.3.0"

同时调试队列php artisan queue:work sqs --sleep=3 --tries=3 如果有错误并解决错误

【讨论】：

谢谢你，我一直坚持添加这个，直到我看到你的评论，我说让我尝试更改 socket.io-client 的版本！

【参考方案2】：

你必须选择聆听 1- 放置您的活动的完整命名空间

window.Echo.channel('test-event')
.listen('App\\Events\\ExampleEvent', (e) => 
    console.log(e);
);

2- 将此事件的名称放入事件文件中

public function broadcastAs()

    return "example-event";

在 Echo 中调用事件，在事件名称前加上（点）

window.Echo.channel('test-event')
.listen('.example-event', (e) => 
    console.log(e);
);
