Laravel控制器方法调用其他“帮助程序”方法


Laravel controller method calling other 'helper' methods

我的控制器中有一个正常运行的用户登录路由,但是该方法本身很长,并且处理了多个问题,例如用户被禁止的可能性,IP日志记录等。我想分解该方法,使其更易于管理,我想知道这是否可能?以下是 'postLogin()' 是路由的 3 种方法:

    public function postLogin()
{
    $validator  =   Validator::make(Input::all(), array(
       'login-username'     =>  'required',
       'login-password'    =>  'required'
    ));
    if($validator->fails())
        return Redirect::back()->withErrors($validator)->withInput();
    else
    {
        $user_attempt    =   Input::get('login-username');
        $pass_attempt    =   Input::get('login-password');
        $auth   =   Auth::attempt(array(
           'username'   =>  $user_attempt,
           'password'   =>  $pass_attempt
        ), true);
        if($auth)
           $this->handleAuth();
        else
            return Redirect::route('home')->with('fail', 'Incorrect username or password, username: ' . $user_attempt . ' pass: ' . $pass_attempt);                  
    }
}
private function handleAuth()
{
    $username       =   Auth::user()->username;
    $banned_info    =   UserBans::getBanned($username);
    $stored_ip      =   Auth::user()->ip_address;
    $current_ip     =   User::getIp();
    if($stored_ip != $current_ip)
        User::updateIp(Auth::user(), $current_ip);
    if(is_null($banned_info))
        return Redirect::intended('/');
    else
        $this->handleBan($banned_info, $current_ip);
}

private function handleBan($banned_info, $current_ip)
{
    if(UserBans::isBanned($banned_info['ban_end']))
    {
        $message    =   "This account is currently banned until: " . $banned_info['ban_end'] . " Reason: " . $banned_info['reason'];
        if($banned_info['ip_address'] != $current_ip)
        {
            $banned_model   =   UserBans::getBannedModel($banned_info['id']);
            User::updateIP($banned_model, $current_ip);
        }
        Auth::logout();
        return Redirect::route('home')->with('fail', $message);
    }
    else
    {
        UserBans::destroy($banned_info['id']);
        return Redirect::intended('/');
    }
}

我发现的问题是主控制器方法将毫无问题地调用辅助方法,但是辅助器方法尝试重定向到路由,例如在handleAuth()中:

if(is_null($banned_info))
        return Redirect::intended('/');

如果用户未被禁止并且具有正确的凭据,则会发生这种情况,通常它会重定向到主页并且您将登录,但是当此方法调用预期时,我在"postLogin"路由 url 处留下了一个空白页面。如果您刷新页面,您将在主页上并已登录。以下是相关路线:

Route::group(array('before' => 'guest'), function()
{ 
    Route::group(array('before' => 'csrf'), function()
    {
        Route::post('/user/login', array('uses' => 'UserController@postLogin', 'as' => 'postLogin'));
    });
});

可以用拉拉维尔路由/控制器吗? 如果没有,你能就如何处理这种情况给出任何建议吗?

handleAuth()return Redirect::intended('/'); 正在向postLogin()返回一些东西。您需要从postLogin()返回该值。

因此,请在postLogin()处添加return

if($auth)
   return $this->handleAuth();

其他修复

handleAuth() 中,还要添加return

else
   return $this->handleBan($banned_info, $current_ip);

看起来你忘了返回句柄Ban() 结果

public function postLogin()
{
   //...
   if($auth)
      return $this->handleAuth();
   //...
}
private function handleAuth()
{
    //...
    if(is_null($banned_info))
        return Redirect::intended('/');
    else
       return $this->handleBan($banned_info, $current_ip);
}
