如何检查用户名和密码匹配 laravel 7

Question

我正在使用 laravel 创建简单的登录表单 7.i 想检查用户名和密码 match.it 是否匹配重定向主页。如果它没有再次重定向登录页面，则显示错误用户名或密码不匹配。我尝试了下面的代码我得到了错误 Call to undefined method App\User::attempt()

登录控制器。

 public function check(Request $request)
    {
    
         $uname = $request->uname;
         $password = $request->password;
         $user = User::where('uname',$a)->get()->last();
         $pass = User::where('password',$b)->get()->last();
    
         if (User::attempt(array('uname' => $uname , 'password' => $password ))){
            return "success";
            }
            else {        
                return "Wrong Credentials";
            }  
    }

型号用户

protected $fillable = [
        'name', 'email', 'password',
    ];

Answer 1

您需要将 User::attempt 替换为 auth()->attempt

另一件事你不需要手动检查 uname 和 passowrd laravel 在 attempt 方法中为你做这件事所以如果你删除那两行

  $user = User::where('uname',$a)->get()->last();
  $pass = User::where('password',$b)->get()->last();

最后，取决于你的 User 型号你有 name 而不是 uname 所以你需要像这样更新它

if (auth()->attempt(array('name' => $uname , 'password' => $password ))){
   return "success";
} else {        
   return "Wrong Credentials";
}
