Question

我正在尝试通过laravel构建实时应用，所以我需要您的忠告帮助我：

我的\ app \ Events \ ExampleEvent.php：

<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

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');
    //return new PrivateChannel('channel-name');
}

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

和我的\ resources \ js \ bootstrap.js

window._ = require('lodash');

/**
 * We'll load jQuery and the Bootstrap jQuery plugin which provides support
 * for JavaScript based Bootstrap features such as modals and tabs. This
 * code may be modified to fit the specific needs of your application.
 */

try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}

/**
 * We'll load the axios HTTP library which allows us to easily issue requests
 * to our Laravel back-end. This library automatically handles sending the
 * CSRF token as a header based on the value of the "XSRF" token cookie.
 */

window.axios = require('axios');

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

/**
 * Next we will register the CSRF Token as a common header with Axios so that
 * all outgoing HTTP requests automatically have it attached. This is just
 * a simple convenience so we don't have to attach every token manually.
 */

let token = document.head.querySelector('meta[name="csrf-token"]');

if (token) {
    window.axios.defaults.headers.common['X-CSRF-TOKEN'] = token.content;
} else {
    console.error('CSRF token not found: https://laravel.com/docs/csrf#csrf-x-csrf-token');
}

/**
 * Echo exposes an expressive API for subscribing to channels and listening
 * for events that are broadcast by Laravel. Echo and event broadcasting
 * allows your team to easily build robust real-time web applications.
 */

// import Echo from 'laravel-echo'

// window.Pusher = require('pusher-js');

// window.Echo = new Echo({
//     broadcaster: 'pusher',
//     key: process.env.MIX_PUSHER_APP_KEY,
//     cluster: process.env.MIX_PUSHER_APP_CLUSTER,
//     encrypted: true
// });

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) => {
        alert('hey');
        console.log(e);
    });

并放入'。 '在事件名称前不能解决问题

和我的\ routes \ web.php

    <?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('test-broadcast', function(){
    broadcast(new \App\Events\ExampleEvent);
});

我已经用：

完成了这些配置

.env：

    APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:Wsmpn4Eg1JEoTgL/cag9aOQTc++Ai6xIcmqn5NBaRJQ=
APP_DEBUG=true
APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

BROADCAST_DRIVER=redis
QUEUE_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

MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=
PUSHER_APP_CLUSTER=mt1

MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"
MIX_PUSHER_APP_CLUSTER="${PUSHER_APP_CLUSTER}"

和 laravel-echo-server.json：

    {
    "authHost": "http://localhost",
    "authEndpoint": "/broadcasting/auth",
    "clients": [],
    "database": "redis",
    "databaseConfig": {
        "redis": {
            "port": "6379",
            "host": "localhost",
            "password": ""
        },
        "sqlite": {
            "databasePath": "/database/laravel-echo-server.sqlite"
        }
    },
    "devMode": true,
    "host": "127.0.0.1",
    "port": "6001",
    "protocol": "http",
    "socketio": {},
    "sslCertPath": "",
    "sslKeyPath": "",
    "sslCertChainPath": "",
    "sslPassphrase": "",
    "subscribers": {
        "http": true,
        "redis": true
    },
    "apiOriginAllow": {
        "allowCors": false,
        "allowOrigin": "",
        "allowMethods": "",
        "allowHeaders": ""
    }
}

那我就跑了

laravel-echo-server start

php artisan serve

redis-cli ping --> gave my pong

以及何时发出事件

并且它必须在控制台中通过bootstrap.js中的window.Echo.channel（）在控制台中打印我在ExampleEvent中的broadcastWith（）中定义的键，但是什么也没有发生，并且控制台是干净的，所以我必须做的事情才能侦听并从客户端

成功打印

我读了很多类似的问题，但是这个问题没有解决

感谢您的帮助和我的问候....

成功广播事件后，客户端不收听任何内容
