Auth::attempt如何知道Table


Laravel How Auth::attempt knows about Table

我的数据库中有两个表1:项目3:用户并试图登录用户,它工作正常,但我的问题是,我没有提到,从哪个表,它将获取数据,但它是从所需的表自动抓取?这是Laravel的功能还是我做错了什么?还是我不明白为什么会这样?

形式
{{ Form::open(array('class'=> 'forming')) }}
    {{ Form::text('username',null,array( 'placeholder' => 'Username' ,'class' => 'insi')); }}<br>
    {{ Form::password('password',array('placeholder'=>'Password', 'class'=>'paswor')); }}<br>
    {{ Form::submit('SignIn!',array('class'=> 'but-n')); }}
{{ Form::close() }}

和AuthController

class AuthController extends Controller{
        public function getLogin(){
            return View::make('login');
        }
        public function postLogin(){
            $rules = array('username'=> 'required', 'password'=>'required');
            $validator = Validator::make(Input::all(),$rules);
            if($validator->fails()){
                return Redirect::route('login')
                    ->withErrors($validator);
            }
            $auth = Auth::attempt(array(
                'username' => Input::get('username'),
                'password' => Input::get('password')
                ), false);
            if(!$auth){
                return Redirect::route('login')
                    ->withErrors(array(
                        'Invalid'
                        ));
            }
            return Redirect::route('home');
        }
}

Auth使用您在file app/config/auth.php中的模型:

如果您正在使用Eloquent驱动程序 for Auth:

/*
|--------------------------------------------------------------------------
| Authentication Model
|--------------------------------------------------------------------------
|
| When using the "Eloquent" authentication driver, we need to know which
| Eloquent model should be used to retrieve your users. Of course, it
| is often just the "User" model but you may use whatever you like.
|
*/
'model' => 'User',

如果您使用的是数据库驱动程序:

/*
|--------------------------------------------------------------------------
| Authentication Table
|--------------------------------------------------------------------------
|
| When using the "Database" authentication driver, we need to know which
| table should be used to retrieve your users. We have chosen a basic
| default value but you may easily change it to any table you like.
|
*/
'table' => 'users',

如果您需要使用多个表进行身份验证,您有一些选择,其中之一是使用这样的结构进行登录:

class Logon {
    public function loginViaEmail($email, $password)
    {
        if ($emailModel = Email::where('email', $email)->first())
        {
            return $this->login($emailModel->user_id, $password);
        }
        return false;
    }
    public function loginViaName($name, $password)
    {
        if ($memberModel = Member::where('name', $name)->first())
        {
            return $this->login($memberModel->user_id, $password);
        }
        return false;
    }
    public function loginViaId($id, $password)
    {
        if ($beingModel = Being::where('id', $id)->first())
        {
            return $this->login($beingModel->user_id, $password);
        }
        return false;
    }
    public function login($id, $password)
    {
        $user = Member::find($id);
        if(Hash::check($password, $user->password))
        {
            Auth::loginUsingId($id);
            return true;
        }
        return false;
    }
}

在控制器中你可以这样写:

$logon = new Logon;
if ( ! $logon->loginViaEmail(Input::get('email'), Input::get('password')))
{
    return "username or password invalid";
}
return "logged in successfully";

...
if ( ! $logon->loginViaName(Input::get('name'), Input::get('password')))
...
