请帮助我在 laravel 5.1 中创建登录和注册页面时收到此错误

FatalErrorException in AuthController.php line 44:
Class 'App\Validator' not found

这是我的 AuthController.php

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

class AuthController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
    |
    */

    use AuthenticatesAndRegistersUsers, ThrottlesLogins;

    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'getLogout']);
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|confirmed|min:6',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

    <div>
        Confirm Password
        <input type="password" name="password_confirmation">
    </div>

    <div>
        <button type="submit">Register</button>
    </div>
</form>

all of the codes are from laravel documention. that's why i dont know why it fails. please check where i get the error. thank you

所有代码都来自laravel文档。这就是为什么我不知道它为什么会失败。请检查我在哪里得到错误。谢谢你

also this is my routes controller

这也是我的路由控制器

// Authentication routes...
Route::get('auth/login', 'Auth\AuthController@getLogin');
Route::post('auth/login', 'Auth\AuthController@postLogin');
Route::get('auth/logout', 'Auth\AuthController@getLogout');

// Registration routes...
Route::get('auth/register', 'Auth\AuthController@getRegister');
Route::post('auth/register', 'Auth\AuthController@postRegister');

P.S. my app is under the domain of http://localhost:8080/QADapps/auth/registeris there any issue because of that? i also move index.php and .htaccess from public into the root directory

PS 我的应用程序在http://localhost:8080/QADapps/auth/register的域下， 因此有什么问题吗？我还将 index.php 和 .htaccess 从 public 移动到根目录

You actually need either this:

你实际上需要的是：

use Validator;

or this:

或这个：

use Illuminate\Support\Facades\Validator;

Illuminate\Validation\Validator is the underlying class containing the functionality but to use the static methods you need to pull in the facade class.

Illuminate\Validation\Validator 是包含功能的底层类，但要使用静态方法，您需要引入外观类。

The facade class Illuminate\Support\Facades\Validator is aliased to Validator in config/app.php

外观类 Illuminate\Support\Facades\Validator 在 config/app.php 中别名为 Validator

May be late here but might help someone later, this is what save use Illuminate\Validation\Rule;

在这里可能会迟到但可能会在以后帮助某人，这就是保存 use Illuminate\Validation\Rule;
