当我登录auth :: check（）返回1但是在我重定向到其他视图或控制器后auth :: check（）返回null我创建新项目whit lavavel 5.5但是没有修复如何解决我的问题？我该怎么办？

user.php的

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
use Notifiable;

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = [
    'ID','Email','first_name','Last_name' ,'username', 'password','typeofuser',
];

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

您正试图以错误的方式访问您的POSTed数据。您应该使用$request对象发布用户的条目。此外，您可以使用单个身份验证条件对用户进行身份验证。用户进行身份验证后，请使用两个简单条件检查其typeofuser字段。像这样：

public function Login(Request $request)
    {
        $credential = $request->only(['username', 'password']);
        if (!Auth::attempt($credential))
            return 'Username or Password is incorrect.';

        // Now you can access to authenticated user model with `users` method in request object
        $user = $request->user();
        if($user->typeofuser == 1)
        {
            $admin = new admin();
            $admin->username = $credential['username'];
            $admin->getuser();
            $user = [$admin->ID,$admin->firstname,$admin->lastname,$admin->email,$admin->phonenumber,$admin->pic,$admin->expirtime];
            return view('Admin_home',['user'=>$user]);
        }
        elseif ($user->typeofuser == 2)
        {
            $std = new students();
            $std->username = $credential['username'];
            $std->getuser();
            $user = [$std->ID,$std->firstname,$std->lastname,$std->email,$std->pic,$std->expirtime];
            return view('Student_home',['user'=>$user]);
        }
        else
            return view('AdminLogin');
    }

为什么我在重定向后得到auth :: check（）null
