【发布时间】：2016-01-06 05:30:50
【问题描述】：

使用社交名流向 Facebook 进行身份验证时出现以下错误。使用 Laravel 5.2，这是我第一次尝试实现 Socialite。有什么想法吗？

FatalErrorException in AbstractProvider.php line 134:
Call to a member function set() on a non-object

路线：-

Route::get('/login', 'AuthController@login');

AuthController.php :-

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class AuthController extends Controller
{
public function login()
{
  return \Socialite::with('facebook')->redirect();
}
}

services.php 设置如下，详细信息在 .env 文件中：-

'facebook' => [
    'client_id'     => env('FACEBOOK_CLIENT_ID'),
    'client_secret' => env('FACEBOOK_CLIENT_SECRET'),
    'redirect'      => env('FACEBOOK_REDIRECT'),
],

这里报告了同样的错误，但没有响应：-https://laracasts.com/discuss/channels/laravel/laravel-socialite-session-errors-in-52/replies/125233

遇到同样的问题...

在这里找到答案：in routes.php, did you define your routes inside the web middleware group? This seems to be a common problem with 5.2 upgrades :)

看起来你必须把你的路由放在一个 MiddleWare 中，因为它包括 AbstractProvider.php 134 中需要的会话创建

$this->request->getSession()->set('state', $state = Str::random(40));

这就是我的代码 routes.php 现在的样子（和工作方式）：

    <?php

/*
|--------------------------------------------------------------------------
| Routes File
|--------------------------------------------------------------------------
|
| Here is where you will register all of the routes in an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('admin', function () {
    return view('admin_template');
});

Route::get('test', 'TestController@index');


/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| This route group applies the "web" middleware group to every route
| it contains. The "web" middleware group is defined in your HTTP
| kernel and includes session state, CSRF protection, and more.
|
*/

Route::group(['middleware' => ['web']], function () {
    //
    Route::get('auth/google', 'Auth\AuthController@redirectToProvider');
    Route::get('auth/google/callback', 'Auth\AuthController@handleProviderCallback');

});

刚刚看到您已经有了相同的链接，现在可以找到答案了......不过还是把它放在这里很好。我现在正在努力处理回调，因为没有用户并且它会引发无效状态。
将路由放入 web 中间件修复了它。谢谢！

【解决方案2】：

您收到此错误的原因是没有启动会话。您必须将 \Illuminate\Session\Middleware\StartSession 中间件分配给您的呼叫路由。

在以前的 Laravel 版本中，这已经在 $middleware 属性中分配，在文件 app/Http/Kernel.php 中找到。

【解决方案3】：

在你的 route.php 中试试这个代码

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::group(['middleware' => ['web']], function () {

    Route::get('/', function () {
        return view('welcome');
    });

});

Route::group(['middleware' => 'web'], function () {
    Route::auth();

    Route::get('/home', 'HomeController@index');

    Route::get('/redirect', 'SocialAuthController@redirect');

    Route::get('/callback', 'SocialAuthController@callback');

});
