在 symfony 中重定向到“/”路由

Question

I'm trying to redirect to the "/" route (same page) after a form submission:我试图在提交表单后重定向到“/”路由（同一页面）：

/**
 * @Route("/")
 */

My approach:我的做法：

return $this->redirectToRoute('/');

Gives me the following error:给了我以下错误：

Unable to generate a URL for the named route "/" as such route does not exist.无法为命名路由“/”生成 URL，因为此类路由不存在。

Answer 1

you have to name the route, like:您必须命名路线，例如：

/**
* @Route("/", name="homepage")
*/

and then:进而：

return $this->redirectToRoute('homepage');

Answer 2

You can try this way:你可以试试这个方法：

/**
 * @Route("/")
 */


return $this->redirect('/');
