在Symfony的url中设置不需要的参数

Question

How to set one action to multiply URLs in Symfony2.8 (annotation type)? I need something like this: /credit/{credit-type} where "credit-type" parameter may be empty: /credit/ I used this:

/**
     * @Route("/{credit}/{credit-type}/", name="credit_page_single", defaults={"credit-type" = "null"})
     * @Method("GET")
     *
     * @param $credit
     * @param $credit-type
     * @param Request $request
     *
     * @return Response
     */

Same thing in Laravel you can get when put the '?' symbol after the parameter that could be empty: /credit/{credit-type?}/

Answer 1

You can set multiple routes to you action, like this :

/**
 * @Route("/{credit}/{credit-type}/", name="credit_page_single", defaults={"credit-type" = "null"})
 * @Route("/{credit}/", name="credit_page_single_without_parameter")
 * @Method("GET")
 *
 * @param $credit
 * @param $credit-type
 * @param Request $request
 *
 * @return Response
 */
