未初始化的字符串偏移量：0 - Laravel auth

Question

我试图通过以下方式检查会话：

<?php

namespace AndyJessop\Socialist\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Auth\Guard;
use AndyJessop\Socialist\AuthenticateUser;

class AuthController extends Controller {

    public $auth;

    public function __construct(Guard $auth)
    {
       $this->auth = $auth;
    }

    public function login($provider, AuthenticateUser $authenticateUser, Request $request)
    {
        $user = $authenticateUser->execute($request->has('code'), $provider);

        return $user;
    }

    public function logout()
    {
        $this->auth->logout();

        return response()->json(['You have been logged out']);
    }

    public function checkSession()
    {
        $session = $this->auth->check();
        return $session;
    }
}

但我收到错误：Uninitialized string offset: 0

这可能是什么原因？

检查数据库表并查看记录。我认为你没有记录。
