Question

我正在使用OAuth2进行Facebook登录，然后我使用Laravel 4内置的身份验证系统重新登录用户。对于大多数用户，我认为没有任何问题，但对于一个用户，他看到登录时出现以下错误：

ErrorException
Argument 1 passed to Illuminate\Auth\Guard::login() must implement interface Illuminate\Auth\UserInterface, null given
open: */nfs/c09/h04/mnt/139243/domains/crowdsets.com/vendor/laravel/framework/src/Illuminate/Auth/Guard.php
*        /**
        * Log a user into the application.
        *
        * @param  \Illuminate\Auth\UserInterface  $user
        * @param  bool  $remember
        * @return void
        */
       public function login(UserInterface $user, $remember = false)
       {
               $id = $user->getAuthIdentifier();

以下是控制器中的相关登录/验证代码：

$check = Fan::where('fbid', '=', $user['uid'])->first();

                if(is_null($check)) {

                  $fan = new Fan;

                  $fan->fbid = $user['uid'];
                  $fan->email = $user['email'];
                  $fan->first_name = $user['first_name'];
                  $fan->last_name = $user['last_name'];
                  $fan->gender = $user['gender'];
                  $fan->birthday = $user['birthday'];
                  $fan->age = $age;
                  $fan->city = $city;
                  $fan->state = $state_abbrev;
                  $fan->image = $user['image'];
                  $fan->friend_ids_url = $user['friends'];
                  $fan->friend_ids_unpacked = $friend_ids;

                  $fan->save();

                  $new = Fan::where('fbid', '=', $user['uid'])->first();

                  Auth::login($new);
                  return Redirect::to('fans/home');

                }

               else {

                  Auth::login($check);

                  $fan = Fan::find(Auth::user()->id);
                  $fan->image = $user['image'];
                  $fan->save();

                  return Redirect::to('fans/home');
                  var_dump($user);

               }

这是我用来保存用户信息的表模型中的代码，称为“粉丝”：

<?php

use Illuminate\Auth\UserInterface;

class Fan extends Eloquent implements UserInterface {
    protected $guarded = array();

    public static $rules = array();

    public function getAuthIdentifier() 
{ 
return $this->getKey(); 
}


public function getAuthPassword() 
{ 
return $this->password; 
}

这非常令人困惑，因为此登录适用于我尝试过的所有其他配置文件。只有这个朋友的个人资料才会抛出这个错误。我还要补充一点，在登录（或重试）时，它将在数据库/表中为该用户创建多个条目。应该设置此身份验证系统以防止这种情况发生。有什么我想念的吗？

Answer 1

在LoginController的create（）方法中，您必须返回$ user 这对我有用

protected function create(array $data)
    {
        $user = User::create([
            'username' => $data['username'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);

        return $user;
    }

Answer 2

尝试将代码重构为：

$fan = Fan::where('fbid', '=', $user['uid'])->first();

if (is_null($fan)) {
    $fan = new Fan;

    $fan->fbid = $user['uid'];
    $fan->email = $user['email'];
    $fan->first_name = $user['first_name'];
    $fan->last_name = $user['last_name'];
    $fan->gender = $user['gender'];
    $fan->birthday = $user['birthday'];
    $fan->age = $age;
    $fan->city = $city;
    $fan->state = $state_abbrev;
    $fan->image = $user['image'];
    $fan->friend_ids_url = $user['friends'];
    $fan->friend_ids_unpacked = $friend_ids;

    $fan->save();
} else {
    $fan->image = $user['image'];
    $fan->save();
}

Auth::loginUsingId($fan->getAuthIdentifier());
return Redirect::to('fans/home');

Answer 3

简单的问题和答案：
您的Fan课程是否延长User课程（或实施UserInterface）？
如果没有，那么最简单的解决方法是

class Fan extends User{
    ....
}

Answer 4

而不是Auth::login($check);或Auth::login($new);，你应该通过，

Auth::login(Auth::user());

Auth :: login（）函数接受第一个参数作为UserInterface对象，如public function login(UserInterface $user, $remember = false)，在函数体中，这将userid像这样$id = $user->getAuthIdentifier();

阅读API文档here。

Answer 6

我有同样的问题，我设法通过检查几件事来解决它：

Argument 1 passed to Illuminate\Auth\Guard::login() must implement interface Illuminate\Auth\UserInterface, null given open:

如您所见，null given表示您想要$user的{{1}}为空。检查它设置的变量。
不要在Auth :: login和最终重定向（）之间放置任何Auth::login($user)。它可能会停止Authentification。

希望有所帮助

传递给Illuminate \ Auth \ Guard :: login（）的参数1必须实现接口Illuminate \ Auth \ UserInterface，null给定open：
