php - Laravel 5 收银员中间件路由错误

Question

我已经从 Laravel 5 实现了收银员/计费功能，我正在尝试使用检查订阅的中间件来保护一组路由。

我收到以下错误:

Argument 2 passed to App\Http\Middleware\HasSubscription::handle() must be an instance of App\Http\Middleware\Closure, instance of Closure given

这是我的中间件

<?php

namespace App\Http\Middleware;

class HasSubscription
{
    public function handle($request, Closure $next)
    {
        if ($request->user() && ! $request->user()->subscribed()) {
            // This user is not a paying customer...
            return redirect('subscription');
        }

        return $next($request);
    }
}

这是我的 protected 路线

Route::get('home', 'PagesController@index')->middleware('subscription');

这是我的应用程序路由声明

protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'subscription' => \App\Http\Middleware\HasSubscription::class,
    ];

知道为什么我在顶部收到错误吗？

Answer 1

只需添加

use Closure;

到中间件的顶部，就在类定义之前:

namespace App\Http\Middleware;

use Closure;

class HasSubscription
{
    ...
