如何在symfony路由中传递数组？

Question

I have a function in my controller that takes an array as input. The value is passed from ajax. At the moment it is not being decoded correctly.

 /**
 * @Route("/userLogin/{params}", name="userLogin", methods={"POST"})
 * @param UserdbRepository $repository
 * @param $params
 * @return \Symfony\Component\HttpFoundation\Response
 */

public function userLogin(UserdbRepository $repository, $params) {

   $email = $params[0];
   $pass = $params[1];

   print_r($params);  // output correct value [e-mail]
   echo $params[0];   // output t
   echo $email;       // output t

   .... rest of code
}

js:

 const array = [ 'email', 'pass' ]

 $.ajax({
    url: `/userLogin/${array}`,
    type: "post",
    dataType: 'json'
})

Answer 1

Use Request component Symfony\Component\HttpFoundation\Request you can autowire it: public function userLogin(UserdbRepository $repository, Request $request)

Example 1: fetch params from requestBody:

$email = $request->request->get('email', null); $email will be null if 'email' parameter not provided in request

don't forget to pass data property in your ajax request

const requestBody = {
    'email': '[e-mail]',
    'pass': '123',
};

$.ajax({
    url: `/userLogin/`,
    type: "post",
    data: requestBody,
});

Note: don't send data in json format. Also you can remove {params} from your @Route pattern and $params argument.

Example 2: fetch 'email' param from queryString:

$email = $request->query->get('email', null);
