自定义消息不会基于Laravel 9.8.1的formrequest返回。

Question

Next is my FormRequest:

    <?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreFruitRequest 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|string|min:3',
        'carbohydrates' => 'required|numeric|gte:0',
        'protein' => 'required|numeric|gte:0',
        'fat' => 'required|numeric|gte:0',
        'calories' => 'required|integer|numeric|gte:0',
        'sugar' => 'required|numeric|gte:0',
    ];
}

/**
 * Error Messages
 *
 * @return array
 */
public function messages() :array
{
    return [
        'carbohydrates.gte' => 'Nutrients cannot be negative',
        'protein.gte' => 'Nutrients cannot be negative',
        'fat.gte' => 'Nutrients cannot be negative',
        'calories.gte' => 'Nutrients cannot be negative',
        'sugar.gte' => 'Nutrients cannot be negative',
    ];
}
}

The validation rules work fine but when I make the request with the wrong value, which is a negative amount, validation does not return these messages to the controller.因此，我的API返回主叶片页面作为错误。

我的代码中有什么不正确？ Or, do I need some tunings anywhere?

Controller (as an answer for @NickSdot):

/**
 * Store a newly created resource in storage.
 *
 * @param StoreFruitRequest $request
 * @return JsonResponse
 */
public function store(StoreFruitRequest $request)
{
    return response()->json(Fruit::create($request->all()) ?? "Cannot create fruit $request->name");
}

您可以在中间件文件夹中添加一个名为forcejsonresponse.php的中间件，然后将其添加到$ MIDDERWARE变量内的kernel.php中。

ForceJsonResponse.php

use Closure;
use Illuminate\Http\Request;

class ForceJsonResponse
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next
     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
     */
    public function handle(Request $request, Closure $next)
    {
        $request->headers->set('Accept', 'application/json');
        return $next($request);
    }
}

Kernel.php

protected $middleware = [
   //your other classes
   \App\Http\Middleware\ForceJsonResponse::class,
];
