Question

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

我收到以下错误消息：

Trait＆＃39; Illuminate \ Foundation \ Auth \ AuthenticatesAndRegistersUsers＆＃39;找不到

这里是AuthController类：

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use 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;

/**
 * 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 \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|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

如果您使用的是Laravel 7+，则需要先运行以下命令来安装laravel/ui软件包（因为它包含auth后端代码）：

$composer require laravel/ui

然后

<?php

use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    use RegistersUsers;
}

Answer 2

与laravel 5.4我们在这个特性上有一些变化。现在我们有两个不同的特征：

use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

如果你安装一个新的5.4 laravel应用程序，你会看到现在你有了LoginController和RegisterController而不是AuthController

Answer 3

我认为你需要使用这个特性

use Illuminate\Foundation\Auth\AuthenticatesUsers;

Answer 4

如果您要迁移到 Laravel 8.x，请考虑将您的身份验证层移至 Laravel Breeze：

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