自定义消息不会从我的应用程序中基于 Laravel 9.8.1 的 FormRequest 返回

Question

下一个是我的FormRequest:

    <?php
namespace AppHttpRequests;
use IlluminateFoundationHttpFormRequest;
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',
    ];
}
}

验证规则工作正常，但是当我使用错误的值(这是一个负值)发出请求时，验证不会将这些消息返回给控制器。因此，我的API返回主刀片页面作为一个错误。

什么是不正确的在我的代码?或者，我需要在任何地方进行调整吗?

控制器(作为@NickSdot的答案):

/**
 * 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");
}

你可以在middleware文件夹中添加一个名为ForceJsonResponse.php的中间件，然后将它添加到Kernel.php的$middleware变量中。

ForceJsonResponse.php

use Closure;
use IlluminateHttpRequest;
class ForceJsonResponse
{
    /**
     * Handle an incoming request.
     *
     * @param  IlluminateHttpRequest  $request
     * @param  Closure(IlluminateHttpRequest): (IlluminateHttpResponse|IlluminateHttpRedirectResponse)  $next
     * @return IlluminateHttpResponse|IlluminateHttpRedirectResponse
     */
    public function handle(Request $request, Closure $next)
    {
        $request->headers->set('Accept', 'application/json');
        return $next($request);
    }
}

Kernel.php

protected $middleware = [
   //your other classes
   AppHttpMiddlewareForceJsonResponse::class,
];
