Laravel 9自定义请求CreateCarRequest无法进入控制器方法问题

我尝试在Laravel中使用自定义请求（custom requests），但找不到问题所在，已查阅官方文档及多语种教程。

我通过以下命令创建了CreateCarRequest类：

php artisan make:request CreateCarRequest

我的CreateCarRequest.php代码如下：

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class CreateCarRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true; // TODO autorizaion logic
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array<string, mixed>
     */
    public function rules(): array
    {
        return [
            'plate' => 'required|string|max:255|unique:cars,plate',
            'brand' => 'required|string|max:255',
            'model' => 'required|string|max:255',
            'seats' => 'required|integer|min:0', // TODO discuss min 0 or 1?
            'fuel' => 'required|string|max:255',
            'priceRent' => 'required|numeric|min:0',
            'type' => 'required|string|max:255',
            'smoke' => 'required|boolean',
            'pet' => 'required|boolean',
            'airConditioner' => 'required|boolean',
            'parkSensor' => 'required|boolean',
            'bluetooth' => 'required|boolean'
        ];
    }
}

使用该请求类的CarsController.php代码如下：

<?php

namespace App\Http\Controllers;

use App\Http\Requests\CreateCarRequest;
use App\Http\Requests\EditCarRequest;
use App\Models\Car;
use Illuminate\Http\RedirectResponse;
use Illuminate\Support\Facades\Log;

class CarsController extends Controller {
    public function show() {
        $cars = Car::paginate(10);
        return view('cars.adminCars', ['cars' => $cars ]);
    }

    public function create() {
        return view('cars.adminCarCreate');
    }

    public function confirmCreate(CreateCarRequest $request): RedirectResponse {
        Log::info('IN CONFIRM CREATE FUNCTION'); // debugging
        $validatedData = $request->validated();
        Log::info($validatedData);
        return redirect()->action([CarsController::class, "create"]);
    }

}

我的问题是始终无法进入confirmCreate方法，通过日志验证发现无任何日志记录。已尝试相关Stack Overflow帖子中的所有解决方案，但均无效。

排查建议 #

• 检查路由配置：确认confirmCreate对应的路由规则正确，请求方式（如POST）与表单提交方式一致，无拼写错误
• 查看验证错误：在adminCarCreate.blade.php视图中添加错误提示代码，验证失败时Laravel会自动重定向并携带错误信息：

  @if($errors->any())
      <div class="alert alert-danger">
          <ul>
              @foreach($errors->all() as $error)
                  <li>{{ $error }}</li>
              @endforeach
          </ul>
      </div>
  @endif
  

• 核对表单字段：确保表单中输入框的name属性与验证规则里的字段完全匹配（如priceRent、airConditioner等驼峰命名字段）
• 清除缓存：执行以下命令清理配置和路由缓存：

  php artisan config:clear
  php artisan route:clear
  

• 检查命名空间：确认CreateCarRequest的命名空间App\Http\Requests正确，控制器中的导入语句无拼写错误
• 查看系统日志：前往storage/logs/laravel.log查看是否有验证失败、路由匹配错误等相关日志记录
