我有facebook登录使用社交网站库。回调发生时会出现问题中的错误。

这是我的" USER"模特

    <?php



namespace App;

use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;

class User extends Model implements Authenticatable  

{
     //use Illuminate\Contracts\Auth\Authenticatable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];


    use \Illuminate\Auth\Authenticatable;

   public function posts()
    {

        return $this->hasMany('App\Post');
    }

    public function likes()
    {
        return $this->hasMany('App\Like');
    }



}

Socialite登录由SocialAuthController处理,我从错误中理解的是, auth() - &gt; login($ user); ,null被传递给登录(&#34; NULL&#34)。这是SocialAuthController的代码。我在这里犯了什么错误以及如何解决这个问题。提前谢谢

   <?php

namespace App\Http\Controllers;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Socialite;
use App\SocialAccountService;

class SocialAuthController extends Controller 
{

public function redirect($provider)
{
    return Socialite::driver($provider)->redirect();
}

use \Illuminate\Auth\Authenticatable;

public function callback(SocialAccountService $service , $provider)
    {
        $user = $service->createOrGetUser(Socialite::driver($provider));

        auth()->login($user);

        return redirect()->to('/home');
    }

}

以下是处理服务,如果帐户已存在,将尝试注册用户或登录。 以下是 SocialAccountService.php

的代码
<?php

namespace App;

use Laravel\Socialite\Contracts\Provider;

class SocialAccountService
{
    public function createOrGetUser(Provider $provider)
    {

        $providerUser = $provider->user();
        $providerName = class_basename($provider); 

        $account = SocialAccount::whereProvider($providerName)
            ->whereProviderUserId($providerUser->getId())
            ->first();

        if ($account) {
            return $account->user;
        } else {

            $account = new SocialAccount([
                'provider_user_id' => $providerUser->getId(),
                'provider' => $providerName
            ]);

            $user = User::whereEmail($providerUser->getEmail())->first();

            if (!$user) {

                $user = User::create([
                    'email' => $providerUser->getEmail(),
                    'name' => $providerUser->getName(),
                ]);
            }

            $account->user()->associate($user);
            $account->save();

            return $user;

        }

    }
}

这将尝试在系统中找到提供商的帐户,如果它不存在,它将创建新用户。如果用户已拥有帐户,此方法还会尝试将社交帐户与电子邮件地址相关联。

我猜测 createOrGetUser()会返回 NULL ,因为 SocialAccount 没有用户。那么可以做的是更改该方法中的 if 条件以检查$account是否有用户:

public function createOrGetUser(Provider $provider)
{
    ...
    if ( $account && property_exists($account, 'user') && $account->user ) {
        return $account->user;
    } else {
    ...
