ubuntu服务器上的laravel websockets和pusher-js CROS问题

Question

我使用了带有echo和pusher js的laravel websockets。这是我的代码：

bootstrap.js：

import Echo from 'laravel-echo'

window.Pusher = require('pusher-js');
window.Pusher.Runtime.createXHR = function () {
    var xhr = new XMLHttpRequest();
    xhr.withCredentials = true;
    return xhr;
};

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: false,
    wsHost: window.location.hostname,
    wsPort: 6001,
    wssPort: 6001,
});

broadcasting.php：

'connections' => [

        'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
                'cluster' => env('PUSHER_APP_CLUSTER'),
                'encrypted' => false,
                'host' => '127.0.0.1',
                'port' => 6001,
                'scheme' => 'https',
                'curl_options' => [
                    CURLOPT_SSL_VERIFYHOST => 0,
                    CURLOPT_SSL_VERIFYPEER => 0,
                ]
            ],
        ],

        'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
        ],

        'log' => [
            'driver' => 'log',
        ],

        'null' => [
            'driver' => 'null',
        ],

    ],

websockets.php

'ssl' => [
        /*
         * Path to local certificate file on filesystem. It must be a PEM encoded file which
         * contains your certificate and private key. It can optionally contain the
         * certificate chain of issuers. The private key also may be contained
         * in a separate file specified by local_pk.
         */
        'local_cert' => env('LARAVEL_WEBSOCKETS_SSL_LOCAL_CERT', null),

        /*
         * Path to local private key file on filesystem in case of separate files for
         * certificate (local_cert) and private key.
         */
        'local_pk' => env('LARAVEL_WEBSOCKETS_SSL_LOCAL_PK', null),

        /*
         * Passphrase for your local_cert file.
         */
        'passphrase' => env('LARAVEL_WEBSOCKETS_SSL_PASSPHRASE', null),

    ],

在本地主机上运行时，一切都正常工作。但是当我试图在服务器上运行它时，我在echo listener页面控制台上得到了这个错误信息：(ubuntu server + ssl)

WebSocket connection to 'wss://example.com/app/ZLZVrjyIVjiXlUCF?protocol=7&client=js&version=5.0.0&flash=false' failed: Error during WebSocket handshake: Unexpected response code: 404

每3秒重复一次！你有什么办法解决这个问题吗？！:(

Answer 1

我通过将pusher-js版本从6.0.0改为5.1.1解决了这个问题。在(Laravel vuejs项目)

Answer 2

在我的例子中，我向config/cors.php添加了以下内容

'paths' => ['api/v1/*', 'stats/*', 'broadcasting/auth'],

并确定了authEndpoint，因为pusher正在另一台服务器上运行

  broadcaster: 'pusher',
  key: process.env.MIX_PUSHER_APP_KEY,
  cluster: process.env.MIX_PUSHER_APP_CLUSTER,
  forceTLS: JSON.parse(process.env.MIX_PUSHER_APP_FORCE_TLS),
  wsHost: process.env.MIX_PUSHER_WS_HOST,
  wsPort: 6001,
  enabledTransports: ['ws', 'wss'],
  authEndpoint: 'http://127.0.0.1:8000/broadcasting/auth',
  auth: {
    headers: {
      Authorization: 'Bearer ' + localStorage.getItem('MY-AUTH-TOKEN')
    }
  }
