Question

我有点像菜鸟;如果我遗漏了一些明显的东西，请原谅我。

我的应用程序中有这个类来设置广播频道（对于Pusher）：

<?php

namespace App\Providers;

use App\Models\Thread;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Broadcast;

class BroadcastServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Broadcast::routes(['middleware' => ['api', 'jwt.auth']]);

        /*
         * Authenticate the user's personal channel...
         */
        Broadcast::channel('users.*.threads', function ($user, $userId) {
            return $user->obfuscated_id == $userId;
        });

        Broadcast::channel('threads.*', function ($user, $threadId) {
            return $user->can('participate', Thread::findByObfuscation($threadId));
        });

        Broadcast::channel('notifications.*', function ($user, $notifiableId) {
            return $user->obfuscated_id == $notifiableId;
        });

        Broadcast::channel('messages.*', function ($user, $userId) {
            return $user->obfuscated_id == $userId;
        });
    }
}

这在Laravel 5.3上工作正常，但在升级（使用Laravel Shift）到5.4后，我开始收到错误：

<!-- language: lang-none -->
Symfony\Component\Debug\Exception\FatalThrowableError: Type error: Too few arguments to function App\Providers\BroadcastServiceProvider::App\Providers\{closure}(), 1 passed in /home/vagrant/Development/Peeps/api/vendor/laravel/framework/src/Illuminate/Broadcasting/Broadcasters/Broadcaster.php on line 68 and exactly 2 expected in /home/vagrant/Development/Peeps/api/app/Providers/BroadcastServiceProvider.php:35

比较Broadcaster.php文件的上一版本和新版本，有一些变化，最可疑的是，这一行：

$parameters = $this->extractAuthParameters($pattern, $channel, $callback);

现在传递一个额外的参数$ callback。

我认为这与回调函数在堆栈中传递的方式有关，我想知道是否有更好的方法来编写对更新的Illuminate类更友好的BroadcastServiceProvider.php。

任何帮助都非常感谢！

I think shift missed a step. Plz follow this to get this solved.

https://laravel.com/docs/5.4/upgrade

在Laravel 5.3中定义通道名称占位符时，使用*字符。在Laravel 5.4中，您应该使用{foo}样式占位符来定义这些占位符，例如路径：

Broadcast :: channel（'App.User。{userId}'，function（$ user，$ userId）{ return（int）$ user-＆gt; id ===（int）$ userId; }）;

Laravel 5.4升级后，BroadcastServiceProvider.php和broadcaster.php发布
