为什么我的laravel 8自定义卫士登录总是返回false

这是config/auth.php

我已经编辑了学生提供商的授权

这是我的学生模型我使用用户模型作为基础编辑了学生模型

<?php
namespace AppModels;
use IlluminateContractsAuthMustVerifyEmail;
use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateFoundationAuthUser as Authenticatable;
use IlluminateNotificationsNotifiable;
class Student extends Authenticatable
{
use HasFactory, Notifiable;
protected $guard = 'student';

/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'first_name',
'last_name',
'email',
'password',
'birthdate',
'Course',
'Year',
];
/**
* 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',
];
}

这是我的学生登录控制器我的登录控制器返回登录表单，下面是总是返回false的登录尝试，因此它总是将我重定向回登录页面。

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use IlluminateSupportFacadesAuth;

use AppHttpControllersController;
// use AppHttpControllersAuthLoginController ;
// use IlluminateFoundationAuthAuthenticatesUsers;


class Student_loginController extends Controller
{
// public function __construct()
//     {
//         $this->middleware('guest:student')->except('logout');


//     }

public function index(){

return view('auth.student_login');
}

public function login(Request $request){

$this->validate($request,
[
'email' => 'required|email',
'password' => 'required',
]);



if(Auth::guard('student')->attempt($request->only('email','password'))){

return redirect()->back()->with('failed',' student not successfully logged in');

}
return redirect('student_dashboard')->with('success','student login');






}
}

这是我的路线
