【问题描述】：
我尝试将 auth::attempt() 用于我的登录页面。但是 auth::attempt() 总是返回 false。我尝试了旧的 stackoverflow 帖子中可用的所有其他方法，但仍然找不到正确的解决方案。我是 laravel 新手，想知道如何在不使用 laravel 身份验证的情况下检查“电子邮件”和“密码”是否与用户表中的任何记录匹配？
users.php

use Illuminate\Database\Eloquent\Model;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
class users extends Authenticatable
{
use Notifiable;
protected $fillable = ['name', 'username', 'password', 'email',];
}

$Name = $req->input('name');
$Username = $req->input('username');
$Password = $req->input('password');
$Password = Hash::make('password');
$Email = $req->input('email');
DB::table("users")->insert(["name"=>$Name,"username"=>$Username,"password"=>$Password,"email"=>$Email]

// DB::table('users')->insert($data);
echo "user inserted";
}
function checklogin(Request $request)
{
$this->validate($request, [
'email' => 'required|email',
'password' => 'required|min:3'
]);
$auth = array(
'email'=>$request->get('email'),
'password'=> $request->get('password'));
//dd($auth);
if(Auth::attempt($auth))
{
// return back()->with('error', 'RIGhT Login Details');
return redirect('student');
}
else
{
return back()->with('error', 'Wrong Login Details');
}
}
function successlogin()
{
return view('studentRegistration');
}
function logout()
{
Auth::logout();
return redirect('index');
}
public function getdata()
{
$data['data']=DB::table('users')->get();
return view('login',$data);
}
}
当我正确输入保存在我的 mysql 中的电子邮件和密码时，我希望 auth::attempt() 会返回 true。我是 laravel 的新手，我需要知道是否有其他方法可以在没有身份验证的情况下验证电子邮件和密码： ：试图（）？ 我受够了这个 auth::attempt() 的事情！ 简而言之： 1) 密码是散列的。 2) Auth::attempt() 总是返回 false 3）我使用mysql db，根据laravel User.php更改users.php模型。
