How to Use custom request (make:request)? (laravel) Method App\Http\Requests\Custom::doesExistI does not exist

问题

I created a custom request to make my own validation. As i follow these article.

I created ProfileRequest

php artisan make:request ProfileRequest

Inside my ProfileRequest

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class ProfileRequest 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 [
            'name' => 'required|min:10',
            'age' => 'required|numeric'
        ]; 
    }
}

My problem is when I use the ProfileRequest inside the controller, like below:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
class ProfileController extends Controller
{
    public function update(ProfileRequest $request){
        return "123";
    }
}

It returns an error like these below:

Class App\Http\Controllers\ProfileRequest does not exist

I need your help Sirs. Somebody know how to use the custom request?

回答1:

In ProfileRequest change extends FormRequest to Request. And add use Illuminate\Http\Request; above the class. Code would like below.

<?php

namespace App\Http\Requests;

use Illuminate\Http\Request;

class ProfileRequest 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()
    {
        return [
            'name' => 'required|min:10',
            'age' => 'required|numeric'
        ]; 
    }
}

And put this App\Http\Requests\ProfileRequest; in above controller.

回答2:

You have imported use Illuminate\Http\Request;

You have to import ProfileRequest instead of Request on your controller,

just this:

use App\Http\Requests\ProfileRequest;

回答3:

Try with this, First of all You have to import request in your controller,

use App\Http\Requests\ProfileRequest;


 $validated = $request->validated();
        if ($validated) {
             // ...
         }

Hope this helps :)

回答4:

You need to import App\Http\Requests\ProfileRequest in your controller

like: use App\Http\Requests\ProfileRequest

then try: composer dumpautoload, php artisan cache:clear

回答5:

In your ProfileRequest.php change

use Illuminate\Foundation\Http\FormRequest;

use Illuminate\Http\FormRequest;

And then just

php artisan config:cache 
composer dumpautoload
