目前使用Kohana 3.3默认路由如果我说控制器用户和操作登录并且我调用/ user / login,一切都很好,操作被调用并执行。
但是现在如果我将url更改为/ user / logins,那么系统找不到任何名为logins的操作并返回错误“Kohana_HTTP_Exception [404]:在此服务器上找不到请求的URL用户/登录。”< / p>
我的问题是,是否有办法强制重定向到/ user / index(默认操作),以防有人在控制器中找不到操作?
喝彩!

您可以override HTTP_Exception_404 class并手动重定向。

实际上你必须覆盖HTTP_Exception_404类。
您可以在那里制作404 NotFound页面。但是如果你想重定向到某个页面 - 你需要做下一步:
class HTTP_Exception_401 extends Kohana_HTTP_Exception_401 {
/**
* Generate a Response for the 401 Exception.
*
* The user should be redirect to a login page.
*
* @return Response
*/
public function get_response()
{
$response = Response::factory()
->status(401)
->headers('Location', URL::site('user/index'));
return $response;
}
}

正如@Darsstar在评论中建议的那样,最好在控制器中的方法之前更改操作,而不是覆盖执行方法。所以在你的用户控制器中就是这样:
protected $default_action = 'index';
public function before()
{
$action = 'action_'.$this->request->action();
if (!empty($this->default_action) && !method_exists($this, $action))
{
$this->request->action($this->default_action);
}
}
因此,如果没有当前操作并且定义了默认操作,则会将当前请求操作更改为默认值。您可以将此代码放入主控制器中,并在子控制器中仅定义$ default_action。
旧回答:
您应该从Controller类重写execute方法。通常它看起来像这样:
public function execute()
{
// Execute the "before action" method
$this->before();
// Determine the action to use
$action = 'action_'.$this->request->action();
// If the action doesn't exist, it's a 404
if ( ! method_exists($this, $action))
{
throw HTTP_Exception::factory(404,
'The requested URL :uri was not found on this server.',
array(':uri' => $this->request->uri())
)->request($this->request);
}
// Execute the action itself
$this->{$action}();
// Execute the "after action" method
$this->after();
// Return the response
return $this->response;
}
将其更改为:
public function execute()
{
// Execute the "before action" method
$this->before();
// Determine the action to use
$action = 'action_'.$this->request->action();
// If the action doesn't exist, check default action
if ( ! method_exists($this, $action))
{
//Can be hardcoded action_index or $this->default_action set in controller
$action = 'action_index';
// If the action doesn't exist, it's a 404
if ( ! method_exists($this, $action))
{
throw HTTP_Exception::factory(404,
'The requested URL :uri was not found on this server.',
array(':uri' => $this->request->uri())
)->request($this->request);
}
}
// Execute the action itself
$this->{$action}();
// Execute the "after action" method
$this->after();
// Return the response
return $this->response;
}
现在,如果操作不存在,则检查默认操作并运行它,或者如果不存在则抛出404.
