PHP HTTP::redirectUntrustedURL方法代碼示例

 /**
  * Handle an unsolicited login operations.

  * to handle IdP initiated SSO. This method will never return.
  *
  * @param string $authId The id of the authentication source that received the request.
  * @param array $state A state array.
  * @param string $redirectTo The URL we should redirect the user to after updating the session. The function will
  * check if the URL is allowed, so there is no need to manually check the URL on beforehand. Please refer to the
  * 'trusted.url.domains' configuration directive for more information about allowing (or disallowing) URLs.
