Question

在Laravel 5.8中，当我尝试listen到专用频道（使用Pusher）时，我在控制台中收到此错误，而且令人惊讶的是，我在Web上找不到任何谈论此错误的地方（特别是首先部分，某处谈论了状态500，但没有帮助。）：

无法从auth端点检索auth字符串-从/ broadcasting / auth接收到状态500。必须对客户端进行身份验证才能加入私人或在线渠道。

Notification.php

class Notification implements ShouldBroadcastNow
{

    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $user;

    /**
     * 
     *
     * @param User $user
     */
    public function __construct(User $user)
    {
        $this->user = $user;

    }

    public function broadcastOn()
    {
       return new PrivateChannel('notif.'.$this->user->id);
    }

    public function broadcastAs()
    {
        return 'Notification';
    }

}

Channels.php

Broadcast::channel('notif.{id}', function ($user, $id) {

    //return (int) $user->id === (int) $id;

     return true;
});

app.js

import Echo from 'laravel-echo'

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

Pusher.logToConsole = true;

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: 'WORKING KEY',
    cluster : "eu",
    encrypted: false,
    csrfToken: 'WORKING TOKEN',
});


window.Echo.private('notif.${id}').listen('.Notification', function (e) {

        console.log(e);

    });

我不需要API授权，项目是基于Web的。

根据此处的本教程 https://laracasts.com/series/get-real-with-laravel-echo/episodes/1

确保您已在应用程序服务提供者下的config / app.php文件中取消对BroadcastServiceProvider.php的注释。

    /*
    * Application Service Providers...
    */
    App\Providers\AppServiceProvider::class,
    App\Providers\AuthServiceProvider::class,
    App\Providers\BroadcastServiceProvider::class,
    App\Providers\EventServiceProvider::class,
    App\Providers\RouteServiceProvider::class,

，以便路由可以浏览Channels.php。

如果仍然无法正常工作，则可以尝试在BroadcastServiceProvider.php中添加一些身份验证，即通过添加auth：api这样的检查：

public function boot()
{
    Broadcast::routes(['middleware' => ['auth:api']]);

    require base_path('routes/channels.php');
}

如果您在api.php路由内使用auth链接。

#EDIT 1

对于任何身份验证问题，您都可以尝试在app / Http / Kernel.php中添加此行

/**
 * The application's route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
    'web' => [
         ..other middleware groups,
        \Laravel\Passport\Http\Middleware\CreateFreshApiToken::class,
    ],

要消耗auth令牌，如Laravel文档中所述： https://laravel.com/docs/5.6/passport#consuming-your-api-with-javascript

我认为您那里缺少一个参数，请尝试以下操作：

import Echo from 'laravel-echo'

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

Pusher.logToConsole = true;

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: 'WORKING KEY',
    cluster : "eu",
    encrypted: true,<-----
    csrfToken: 'WORKING TOKEN',
    authEndpoint: 'https://yourwebsitename.com/broadcasting/auth', <-----
});


window.Echo.private('notif.${id}').listen('.Notification', function (e) {

        console.log(e);

    });

无法从身份验证端点检索身份验证字符串-接收状态500
