Php Laravel/Socialite:类Laravel\Socialite\Contracts\Factory不存在

我试图实现社交名流，但我得到了一个与工厂类相关的错误。我的应用程序找不到它

这是我的控制器中的代码：

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

use Laravel\Socialite\Contracts\Factory as Socialite;

class PortalController extends Controller
{

    public function __construct(Socialite $socialite){
           $this->socialite = $socialite;
       }


    public function getSocialAuth($provider=null)
    {
       if(!config("services.$provider")) abort('404'); //just to handle providers that doesn't exist

       return $this->socialite->with($provider)->redirect();
    }


    public function getSocialAuthCallback($provider=null)
    {
       if($user = $this->socialite->with($provider)->user()){
          dd($user);
       }else{
          return 'something went wrong';
       }
    }

我收到的错误是：

Container.php第798行中的ReflectionException： 类Laravel\Socialite\Contracts\Factory不存在

从中，在config/app.php文件中将Socialite库和facade添加到相应的提供者和别名数组后，只需将Socialite用作

use Socialite;

但是你正在使用

use Laravel\Socialite\Contracts\Factory as Socialite;

所以，只需使用

use Socialite;

根据评论更新

及

它应该会起作用

表示您需要使用此选项：

use Socialite;

而不是：

use Laravel\Socialite\Contracts\Factory as Socialite;

如果不起作用，请尝试使用：

use Laravel\Socialite\Facades\Socialite

---

然后使用composer dumpauto。

composer update为我解决了这个问题，它可以使用：使用Laravel\Socialite\Contracts\Factory作为Socialite

在创建自定义oAuth提供程序时，我在Laravel5.5中也遇到了这个问题。经过长时间的研究，我通过创建自定义MySocialServiceProvider类实现了这一目标，需要通过Laravel\Socialite\SocialiteServiceProvider进行扩展。请仔细阅读下面的所有代码并使用适当的配置进行设置，它肯定会工作

我的目录结构如下图所示

MySocialServiceProvider.php

最后，我们应该在config/services.php中添加配置值

'foo' => [
        'client_id' => 'XXXXXXXX',
        'client_secret' => 'YYYYYYYY',
        'redirect' => 'http://example.com/login/foo/callback/',
        'url' => 'https://auth.foobar.com',
    ],

别忘了用我们的新提供者更新config/app.php

'providers' => [
//...

 \App\Providers\MySocialServiceProvider::class

]

您是否使用composer转储自动加载？然后尝试使用Laravel\Socialist\Facades\Socialist；我也试过了，但不起作用：Laravel\Socialite\Facades\Socialite类不存在。我想您还没有安装该软件包。您的供应商文件夹中是否有Socialite文件夹？它现在可用于use Laravel\Socialite\Facades\Socialite；在我更新了composer之后。非常感谢你的帮助！尝试使用composer dumpauto。如果不起作用，请尝试使用Laravel\Socialite\Facades\Socialite；你能告诉我当你使用use Socialite时导致错误的那一行吗？它现在与use Laravel\Socialite\Facades\Socialite一起工作；在我更新了composer之后。非常感谢你的帮助！很高兴这有帮助。如果你想感谢我的时间，请选择我的答案作为最佳答案。太棒了你救了我一天
