laravel - 在中间件中修改请求？

Question

我有一个 TrimInput 中间件注册为我的路由的中间件，用于在请求到达 Controller 之前修剪所有用户输入。在中间件中，修剪似乎有效，但是当我在操作中转储请求时，请求似乎未修改，就像之前没有中间件一样。

这里有什么问题？问题是 ClientRequest 但为什么呢？

// TrimInput.php
<?php namespace App\Http\Middleware;

use Closure;

class TrimInput {

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request $request
     * @param  \Closure $next
     *
     * @return mixed
     */
    public function handle($request, Closure $next) {
        $request->replace($this->trimArrayRecursive($request->all()));
        // When I dump $request right here, all seems fine (the input is trimmed)

        return $next($request);
    }

    protected function trimArrayRecursive($input) {
        if (!is_array($input)) {
            return trim($input);
        }

        return array_map([$this, 'trimArrayRecursive'], $input);
    }

}


// Somwhere in my routes.php
Route::post('/test', ['middleware' => 'trim', 'uses' => function(\App\Http\Requests\ClientRequest $request) {
    dd($request->all()); // Unfortunately dumps the unfiltered (untrimmed) input
}]); 

编辑:原来，上面的代码是有效的，但不幸的是我的 ClientRequest忽略 TrimInputMiddleware .

// ClientRequest.php
<?php namespace App\Http\Requests;

class ClientRequest extends Request {

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize() {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules() {
        $idToIgnore = $this->input('id');

        return [
            'name'           => 'required|max:255|unique:clients,name,' . $idToIgnore,
            'street'         => 'required|max:255',
            'postal_code'    => 'required|digits:5',
            'city'           => 'required|max:255',
            'contact_person' => 'required|max:255'
        ];
    }

}

您应该首先在您的 中为中间件分配一个速记键。 app/Http/Kernel.php 文件。像下面

protected $routeMiddleware = [
    'auth' => 'App\Http\Middleware\Authenticate',
    'auth.basic' => 'Illuminate\Auth\Middleware\AuthenticateWithBasicAuth',
    'guest' => 'App\Http\Middleware\RedirectIfAuthenticated',
    'trim' => 'App\Http\Middleware\TrimInput ',
];
