如何使用自定义请求（make：request）？ （laravel）方法App \ Http \ Requests \ Custom :: doesExistI不存在

Question

我创建了一个自定义请求以进行自己的验证。当我遵循这些article时。

我创建了 ProfileRequest

php artisan make:request ProfileRequest

在我的 ProfileRequest

中

<?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'
        ]; 
    }
}

---

我的问题是，当我在控制器内使用 ProfileRequest 时，如下所示：

namespace App\Http\Controllers;

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

它返回如下错误：

Class App\Http\Controllers\ProfileRequest does not exist

先生，我需要您的帮助。有人知道如何使用自定义请求吗？

Answer 1

在 ProfileRequest 中，更改将FormRequest扩展到Request。并在课程上方添加use Illuminate\Http\Request;。代码如下。

<?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'
        ]; 
    }
}

并将此App\Http\Requests\ProfileRequest;放在上面的控制器中。

您需要在控制器中导入print("Covert binary to decimal (Example: 1011 = 11)"); binary = input("Enter number in Binary Format: "); try: #convert input to integer binary_con = int(binary) #convert binary to decimal decimal = int(binary, 2); #print decimal print(binary,"in Decimal =",decimal); #if error print input number is not a interger(1 or 0) except ValueError: #print message input number is not binary print("That's not a Binary number")

like：App\Http\Requests\ProfileRequest

然后尝试：use App\Http\Requests\ProfileRequest，composer dumpautoload

Answer 3

您已导入use Illuminate\Http\Request;

您必须在控制器上导入ProfileRequest而不是Request，

就这样：

use App\Http\Requests\ProfileRequest;

Answer 4

尝试一下， 首先，您必须在控制器中导入请求，

use App\Http\Requests\ProfileRequest;


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

希望这会有所帮助：）

Answer 5

在您的ProfileRequest.php中 更改

$(".twentytwenty-container").twentytwenty({
    before_label: 'Before',
    after_label: 'After'
});

到

use Illuminate\Foundation\Http\FormRequest;

然后

use Illuminate\Http\FormRequest;

Answer 6

创建ProfileRequest

php artisan make:request Profile/ProfileRequest

在ProfileRequest内部

<?php

namespace App\Http\Requests\Profile;

use Illuminate\Foundation\Http\FormRequest;

class ProfileUpdate 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'
        ]; 
    }
}

然后在控制器中使用App\Http\Requests\Profile\ProfileRequest。
