Question

我有一个TrimInput中间件注册为我的路由的中间件，以便在请求到达控制器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，请求似乎没有修改，就像以前没有中间件一样。

~~这里有什么问题？~~问题是ClientRequest，但为什么？

// 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：结果是，上述代码正常运行，但遗憾的是我的ClientRequest忽略了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'
        ];
    }

}

您应首先在 app / Http / Kernel.php 文件中为中间件分配一个简写密钥。如下所示

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

Answer 2

为了使中间件能够修改FormRequest上的请求输入，您需要使用all()上的/app/Http/Requests/Request.php方法覆盖它，因为它是在中间件之前加载的被执行。我认为这在Laravel 5.4中得到了修复。

这对我有用。在Request.php中添加此方法，它将应用在中间件中完成的更改。

public function all()
{
    $this->merge( $this->request->all() );

    return parent::all();
}

使用框架的Illuminate \ Foundation \ Http / Middleware \ TrimStrings.php 中间件并将其添加到您的web中间件组

修改中间件中的请求？
