php - Laravel 5.8自定义验证错误 'class does not exist'

Question

我是 Laravel 的新手，我正在尝试让自定义验证规则在我的 Controller 上工作。 显示该类不存在。

ReflectionException thrown with message "Class App\Http\Controllers\StoreBooksRequest does not exist"

我使用 artisan 命令制作了请求文件。

lando artisan make:request StoreBooksRequest

这是我的请求文件:

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreBooksRequest 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 [
            //
            'title' => 'required|unique:books|max:150',
            'description' => 'required',
            'isbn' => 'required|max:20'
        ];
    }
}

这是我试图让自定义请求规则发挥作用的 Controller :

namespace App\Http\Controllers;

use App\Book;
use Illuminate\Http\Request;

class BooksController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        //
        $books = Book::all();

        return view('books.index', compact('books'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('books.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(StoreBooksRequest $request)
    {
        $book = new Book();

        $book->title = $request->title;
        $book->description = $request->description;
        $book->isbn = $request->isbn;

        $book->save();
    }

我认为问题在于错误指出请求文件位于 Controllers 文件夹中，而不是位于标准 Requests 文件夹中。

您尚未包含自定义请求类的命名空间。在 use Illuminate\Http\Request; 之后添加 use App\Http\Requests\StoreBooksRequest;
