Laravel：未找到特征"Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers"

Question

我正在更新到Laravel 5.4，并且在尝试显示登录屏幕时会收到以下错误消息。

我正在收到以下错误消息：

特质'照明 Foundation Auth AuthentIcatesAndRegisterSUSERS未找到

这是Authcontroller类：

<?php
namespace AppHttpControllersAuth;
use AppUser;
use Validator;
use AppHttpControllersController;
use IlluminateFoundationAuthThrottlesLogins;
use IlluminateFoundationAuthAuthenticatesAndRegistersUsers;
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;
/**
 * Where to redirect users after login / registration.
 *
 * @var string
 */
protected $redirectTo = '/home';
/**
 * Where to redirect users after logout.
 *
 * @var string
 */
protected $redirectAfterLogout = '/login';
/**
 * Create a new authentication controller instance.
 *
 * @return void
 */
public function __construct()
{
    $this->middleware($this->guestMiddleware(), ['except' => ['getLogout']]);
}
/**
 * Get a validator for an incoming registration request.
 *
 * @param  array  $data
 * @return IlluminateContractsValidationValidator
 */
protected function validator(array $data)
{
    return Validator::make($data, [
        'name' => 'required|max:255',
        'email' => 'required|email|max:255|unique:users',
        'password' => 'required|min:6|confirmed',
    ]);
}
/**
 * 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']),
    ]);
}
}

Answer 1

如果您在Laravel 7 中，则需要首先通过运行以下命令来安装laravel/ui软件包(因为这包含auth backend代码(：

$composer require laravel/ui

，然后

<?php
use IlluminateFoundationAuthRegistersUsers;
class RegisterController extends Controller
{
    use RegistersUsers;
}

Answer 2

laravel 5.4我们在此特征上有一些变化。现在我们有两个不同的特征：

use IlluminateFoundationAuthRegistersUsers;
use IlluminateFoundationAuthAuthenticatesUsers;

，如果您安装了新鲜的5.4 Laravel应用程序，您将看到您现在有LoginController和register Controller而不是AuthController

Answer 3

我认为您需要使用此特征

use IlluminateFoundationAuthAuthenticatesUsers;

Answer 4

如果您要迁移到Laravel 8.x考虑将身份验证层移至Laravel Breeze：

$ composer require laravel/breeze --dev
$ php artisan breeze:install
