php - 使用 Laravel 5.1 登录 Facebook Socialite

Question

我已按照 http://laravel.com/docs/5.1/authentication 中的所有步骤进行操作在 Laravel 5.1 上使用 facebook 进行社交登录。

这里是我遵循的步骤:

1 - 在我的 Laravel 根项目中使用命令:

composer require laravel/socialite

2 - 在你的 config/app.php 配置文件中注册 Laravel\Socialite\SocialiteServiceProvider:

'providers' => [
    // Other service providers...

    Laravel\Socialite\SocialiteServiceProvider::class,
],

3 - 将 Socialite facade 添加到应用配置文件中的别名数组:

'Socialite' => Laravel\Socialite\Facades\Socialite::class,

4 - 在 config/services.php 中添加 facebook 服务:

 'facebook' => [
        'client_id' => env('FACEBOOK_CLIENT_ID'),
        'client_secret' => env('FACEBOOK_CLIENT_SECRET'),
        'redirect' => 'http://homestead.app/auth/facebook/callback',
    ],

5 - 将方法 redirectToProvider() 和 handleProviderCallback() 添加到我的 AuthController.php 中:

<?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;
use Socialite;

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;

    /**
     * Redirect path after successful login
     *
     * @var string
     */
    protected $redirectPath = '/greeting';

    /**
     * Redirect path after failed login
     *
     * @var string
     */
    protected $loginPath = '/auth/login';

    /**
     * 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']),
        ]);
    }

    /**
     * Redirect the user to the Facebook authentication page.
     *
     * @return Response
     */


    public function redirectToProvider()
    {
        return Socialite::driver('facebook')->redirect();
    }

    /**
     * Obtain the user information from Facebook.
     *
     * @return Response
     */
    public function handleProviderCallback()
    {
        $user = Socialite::driver('facebook')->user();

        dd($user);
    }
}

我想强调一下，我已经在文件夹 app/Http/Controllers/Auth/中创建了 AuthController.php，因为在它要求创建路由之后:'Auth\AuthController@redirectToProvider''Auth\AuthController@handleProviderCallback'

6 - 我已经添加了路线:

Route::get('auth/facebook', 'Auth\AuthController@redirectToProvider');
Route::get('auth/facebook/callback', 'Auth\AuthController@handleProviderCallback');

现在，当我在登录页面中单击“使用 facebook 登录”时，它会转到 http://homestead.app/auth/facebook并给我以下错误:

FatalErrorException in AuthController.php line 90: Class 'Socialite' not found

我尝试关注代码 anchor guide但它适用于 laravel 5.0(我需要在 laravel 5.1 上使用它)

最后我通过删除所有内容并从头开始重新安装 Homestead 解决了问题
