嗨，我对拉拉维尔很陌生。我被要求在拉拉维尔中创建应用程序。现在，最初，我正在研究登录模块。
基本要求
- 当用户登录时，将登录页面显示为登录页面。
- 提供用户凭据后，应设置会话，并且用户必须重定向到内页。
- 成功登录后，除非注销，否则不应显示登录页面。
因此，为了检查登录状态，我在过滤器中使用了过滤器.php如下所示。
App::before(function($request)
{
// $myApp Singleton object
App::singleton('myApp', function(){
$app = new stdClass;
$app->title = "APD | Dealership Invoicing";
if (Auth::check()) {
$app->user = Auth::User();
$app->isLogedin = TRUE;
}
else
{
$app->isLogedin = FALSE;
$app->user = FALSE;
}
return $app;
});
$app = App::make('myApp');
View::share('myApp', $app);
});
我根据" http://heera.it/laravel-4-view-composer-master-layout#.VH280nvB25s"中发布的博客实现了上述代码。
当用户从视图中单击登录按钮时，我将数据发送到控制器并检查数据库中的数据，如果数据正确，那么我将用户详细信息放在会话中并重定向到内部页面。
控制器代码
public function validateLogin()
{
$data = Input::all();
$user_data = $this->validate_user_login($data);
if(is_array($user_data) && !empty($user_data) && count($user_data) > 0)
{
/* The below conversion is used, because there seems to be difficulty in returning the Arrays from the Eloquent ORM.*/
$user_array = (array)$user_data[0];
Session::put('user_data', $user_array);
return Redirect::to('/jobs');
}
}
路线.php代码
Route::get('/', function()
{
#return View::make('login/login');
return Redirect::to('/login');
});
Route::get('/login', 'UserController@login');
Route::post('/user/validate_login', 'UserController@validateLogin');
Route::group(array('before' => 'auth'), function()
{
Route::get('/jobs', 'JobsController@jobs_list');
});
但我的问题是，重定向将我带回登录页面。
问题
- 登录后如何将登录状态设置为 true？
- 如何启动会话。我在控制器中设置了会话密钥，这足以验证用户会话吗？
- 将来，我必须为相同的应用程序开发REST API，我必须为Web和服务平台使用相同的应用程序。因此，基于将控件放入过滤器中会在 API 调用中遇到任何困难？
- 我在哪里可以找到"Auth：：Check(("中的身份验证类和检查函数？
我通过使用
Jeffrey 在"https://laracasts.com/series/laravel-from-scratch/episodes/15"中的教程实现了登录功能。这是简单而伟大的解释。我已经用Jeffrey解释的方式更改了我编写的代码。效果很好。
我将提供简短的登录功能，这是我在视频之后构建的。
路由器文件
Router.php
----------
/* This route is used to show the login page, when there is no session created.*/
Route::group(array('before' => 'login'), function()
{
Route::get('login', 'UserController@create');
});
/* This below route is used when user is clicked on the login button in the log in page. */
Route::post('/user/store','UserController@store');
过滤器文件
Filter.php
----------
App::before(function($request)

$app->user = Auth::User();
$app->isLogedin = TRUE;
}
else
{
$app->isLogedin = FALSE;
$app->user = FALSE;

return $app;

$app = App::make('myApp');
View::share('myApp', $app);

$response->headers->set("Cache-Control","no-cache,no-store, must-revalidate");
$response->headers->set("Pragma", "no-cache"); //HTTP 1.0
$response->headers->set("Expires"," Sat, 26 Jul 1986 05:00:00 GMT");
});
/*

Route::filter('auth', function()
{
if (Auth::guest())
{
if (Request::ajax())
{
/*return Response::make('Unauthorized', 401);*/
return Response::make('common.unauthorized');
}
else
{
return Redirect::guest('login');
}
}
});
控制器文件
UserController.php
------------------
/**
* The below function is used to show the login screen.
*/
public function create()
{
/*
This helps us to restrict the display of login page when clicked on browser back button after login.
*/
$headers = array();
$headers['Expires'] = 'Tue, 1 Jan 1980 00:00:00 GMT';
$headers['Cache-Control'] = 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0';
$headers['Pragma'] = 'no-cache';
return Response::make(View::make('login.login'), 200, $headers);
//return View::make('login.login');
}
public function store()
{
$input_data = Input::all();
$credentials = array(
'user_name' => htmlEncode(trim($input_data['user_name'])),
'password' => $input_data['password'],
'status' => 1
);
/* Here I am calling a function in the parent class. My UserController is extending the BaseController. The code will be available below. */
$loginStatus = $this->validateUserLogin($credentials);
if($loginStatus['status'] == 200)
{
$roleId = Auth::User()->role_id;
$loggedInUserId = Auth::User()->id;
$redirectPage = '/products';
switch ($roleId)
{
case 'super':
$redirectPage = '/manage_users';
break;
case 'admin':
$redirectPage = '/products';
break;
}
return Redirect::to($redirectPage);
}
else
{
return Redirect::to('login')->with('status_data',$loginStatus);
}
}
基本控制器文件
BaseController.php
------------------
protected function validateUserLogin($userData = '')
{
$this->return_array = array();
if(!empty($userData))
{
if(Auth::attempt($userData))
{
$this->return_array['status'] = 200;
$this->return_array['message'] = 'Login successfull.';
}
else
{
$userData['status'] = 0;
if(Auth::validate($userData)) // This is to verify weather user is existed with status '0'. That means De-active user.
{
$this->return_array['status'] = 100;
$this->return_array['message'] = 'Your account is deactivated, Please contact your admin.';
}
else
{
$this->return_array['status'] = 100;

}
}
}
else
