Laravel 5.7-覆盖请求验证类中的all()方法以验证路由参数? [英] Laravel 5.7 - Override all() method in Request validation Class to validate route parameters?

问题描述

我想在Request验证类中验证路由参数.我知道这个问题已经被问过很多次了，但是根据这个问题我重写all()方法，并收到此错误:

I want to validate the route parameters in the Request validation class. I know this question has been asked many times before but According to this question I override all() method and I receive this error:

Class App\Http\Requests\DestroyUserRequest does not exist

我正在使用Laravel 5.7.

I'm using Laravel 5.7.

路线:

Route::delete('/user/{userId}/delete', 'UserController@destroy')->name('user.destroy');

控制器:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests\DestroyUserRequest;
use App\User;

class UserController extends Controller
{

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function destroy(DestroyUserRequest $request)
    {
        User::find($request->route('userId'))->delete();
        return $request->route('userId');
    }
}

DestroyUserRequest:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class DestroyUserRequest extends FormRequest
{
    /**
     * 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()
    {
        return [
            'userId' => 'integer|exists:users,id'
        ];
    }

    public function all()
    {
        $data = parent::all();
        $data['userId'] =  $this->route('userId');
        return $data;
    }
}

重写all()方法有什么问题?

What is wrong to override all() method?

推荐答案

您得到的错误似乎很奇怪.我认为问题出在这里，因为您的方法签名与父代签名不同.

The error your get seems to be quite strange. I believe the problem is here because your method signature is not the same as parent.

应该是:

public function all($keys = null)
{
    $data = parent::all($keys);
    $data['userId'] =  $this->route('userId');
    return $data;
}

因为Illuminate/Http/Concerns/InteractsWithInput.php的签名是:

/**
 * Get all of the input and files for the request.
 *
 * @param  array|mixed  $keys
 * @return array
 */
public function all($keys = null)

在Laravel 5.5中进行了更改.您可以阅读升级指南:

The change was made in Laravel 5.5. You can read in upgrade guide:

所有方法

如果要覆盖Illuminate \ Http \ Request的all方法 类，您应该更新方法签名以反映新的 $ keys参数:

If you are overriding the all method of the Illuminate\Http\Request class, you should update your method signature to reflect the new $keys argument:

公共函数all($ keys = null){

public function all($keys = null) {
