Question

我使用Google和Facebook进行了社交名流登录，但是在SocialiteController部分中出现了类似上述问题的错误。

这是我的SocialiteController

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Laravel\Socialite\Facades\Socialite;
use Illuminate\Support\Facades\Auth;
use Spatie\Permission\Models\Role;
use App\SocialAccount;
use App\User;

class SocialiteController extends Controller
{
    public function redirectToProvider($provider)
    {
        return Socialite::driver($provider)->redirect();
    }

    public function handleProviderCallback($provider)
    {
        $user = Socialite::driver($provider)->user();
        $authUser = $this->findOrCreateUser($user, $provider);
        Auth::login($authUser, true);
        return redirect('/personal');
    }

    public function findOrCreateUser($socialUser, $provider)
    {
        $socialAccount = SocialAccount::where('provider_id', $socialUser->getId())
                        ->where('provider_name', $provider)
                        ->first();

        if($socialAccount) {
            return $socialAccount->user;
        } else {
            $user = User::where('email', $socialUser->getEmail())->first();
            if(!$user) {
                $user = User::create([
                    'username' => $socialUser->getName(),
                    'email' => $socialUser->getEmail()

                ]);
                $user->assignRole('Registered');
            }

            $user->socialAccounts()->create([
                'provider_id' => $socialUser->getId(),
                'provider_name' => $provider
            ]);

            return $user;
        }
    }
}

这是我的用户模型

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Spatie\Permission\Traits\HasRoles;
use App\Profile;
use App\Article;
use App\Video;
use App\Images;
use App\News;

class User extends Authenticatable Implements MustVerifyEmail
{
    use Notifiable, HasRoles;
    protected $table = "users";
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'username', 'email', 'password'
    ];


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

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function profile(){
        return $this->hasOne(Profile::class);
    }

    public function article()
    {
        return $this->hasMany(Article::class);
    }

    public function socialAccounts()
    {
        return $this->hasOne(SocialAccount::class);
    }

    public function video(){
        return $this->hasMany(Video::class);
    }

    public function news(){
        return $this->hasMany(News::class);
    }
}

完整的错误消息如下：传递给Illuminate \ Auth \ SessionGuard :: login（）的参数1必须实现Illuminate \ Contracts \ Auth \ Authenticatable接口，给定为null，在/ home / asyj6686 / public_html / sublaravel / vendor / laravel / framework / src / Illuminate / Auth中调用/AuthManager.php，第297行

传递给Illuminate \ Auth \ SessionGuard :: login（）的参数1必须实现Illuminate \ Contracts \ Auth \ Authenticatable接口，给定null

此错误非常简单。这意味着您已经向登录名传递了null值。

Auth::login($authUser, true);

我看不到所提供的代码有什么问题。因此，我猜测您可能只是忘记了在 SocialAccount 模型中添加与 User 的逆关系。这将导致$socialAccount->user返回null并生成您收到的错误。

App \ SocialAccount.php

class SocialAccount extends Model
{
    // ...

    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

请注意，用户应该不能->hasMany() SocialAccount 吗？
