使用Laravel 5.1登录Facebook社交名流

Question

我已按照http://laravel.com/docs/5.1/authentication中的所有步骤进行操作，以在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-在您的config / app.php配置文件中注册Laravel \\ Socialite \\ SocialiteServiceProvider：

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

    Laravel\Socialite\SocialiteServiceProvider::class,
],

3-将Socialite外观添加到应用程序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，并显示以下错误：

AuthController.php第90行中的FatalErrorException：找不到类'Socialite'

我尝试遵循编解码器指南，但它适用于laravel 5.0（我需要在laravel 5.1上使用它）

最后，我解决了删除所有内容并从头开始重新安装Homestead的问题。
