zenframework2 route跳转后为什么域名会变成localhost
我访问 http://xxx.com/webcav/application/index/login 跳转后变成了
http://localhost/webcav/application/index/login
（同一个action处理显示和登陆，所以要跳转到同样的地址）

处理代码如下

 public function loginAction()
    {
    	$flashMessenger=$this->flashMessenger();
    	$message='';
    	if($flashMessenger->hasMessages())
    	{
    		$message_array=$flashMessenger->getMessages();
    		$message = $message_array[0];
    		
    		
    	}
    	
    	$form =new UserForm();

    	$form-> get('submit')->setValue('繝ｭ繧ｰ繧､繝ｳ');
    	$request=$this->getRequest();
    	if($request->isPost())
    	{
    		$this->getTranslator()->addTranslationFile('phparray','/var/www/zend2/vendor/ZF2/resources/languages/ja/Zend_Validate.php');
  		
    		$user=new User();
    		$form->setInputFilter($user->getInputFilter());
			$form->setData($request->getPost());
			
			if($form->isValid())
			{
				$user->exchangeArray($form->getData());
				$auth =new Auth();
				if($auth->login($user,$this->getDBAdapter()))
				{
					$this->flashMessenger()->addMessage('繝ｭ繧ｰ繧､繝ｳ縺悟ｮ御ｺ・＠縺ｾ縺励');
					return $this->redirect()->toRoute('application',array(
							'controller'=>'user',
							'action'=>'index'
						));
				}else{
					$message="繝ｭ繧ｰ繧､繝ｳ縺ｫ螟ｱ謨励＠縺ｾ縺励";
				}
				
			}
			
    	}    	
    	
    	$values=array(
    		'form'=>$form,
    		'message'=>$message,
    	);
    	$view =new ViewModel($values);
    	return $view;
    }
    

module.config.php

return array(
    'router' => array(
        'routes' => array(
            'home' => array(
                'type' => 'Zend\Mvc\Router\Http\Literal',
                'options' => array(
                    'route'    => '/',
                    'defaults' => array(
                        'controller' => 'Application\Controller\Index',
                        'action'     => 'index',
                    ),
                ),
            ),
            // The following is a route to simplify getting started creating
            // new controllers and actions without needing to create a new
            // module. Simply drop new controllers in, and you can access them
            // using the path /application/:controller/:action
            'application' => array(
                'type'    => 'Segment',
                'options' => array(
                    'route'    => '/application[/:controller[/:action[/:id]]]',
                    'defaults' => array(
                        '__NAMESPACE__' => 'Application\Controller',
                        'controller'    => 'Index',
                        'action'        => 'index',
                    ),
                ),
                'may_terminate' => true,
                'child_routes' => array(
                    'default' => array(
                        'type'    => 'Segment',
                        'options' => array(
                            'route'    => '/[:controller[/:action[/:id]]]',
                            'constraints' => array(
                                'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
                                'action'     => '[a-zA-Z][a-zA-Z0-9_-]*',
                            ),
                            'defaults' => array(
                            ),
                        ),
                    ),
                ),
            ),
        ),
    ),

最可能出现问题的地方view

<?php if(strlen($message)):?>
<div style='padding:4px;margin:4px;border:dotted 2px #448800; background:#ddffdd;'>
<?php echo $message;?>
</div>
<?php endif;?>
<?php

$form=$this->form;
$form->setAttribute('action',$this->url(
'application',array('controller'=>'index','action'=>'login')
));

echo $this->form()->openTag($form);
echo $this->formHidden($form->get('id'));
echo $this->formRow($form->get('email'));
echo $this->formRow($form->get('password'));
echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();

?>
