如何在symfony路由中传递数组？

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 test@test.com
   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'
})

图片转代码服务由CSDN问答提供 功能建议

我的控制器中有一个函数，它将数组作为输入。 该值从ajax传递。 目前它没有被正确解码。 

  / ** 
 * @Route（“/ userLogin / {params}”，name =“userLogin”，methods =  {“POST”}）
 * @param UserdbRepository $ repository 
 * @param $ params 
 * @return \ Symfony \ Component \ HttpFoundation \ Response 
 * / 
 
公共函数userLogin（UserdbRepository $ repository，$  params）{
 
 $ email = $ params [0]; 
 $ pass = $ params [1]; 
 
 print_r（$ params）;  //输出正确的值test@test.com 
 echo $ params [0];  //输出t 
 echo $ email;  //输出t 
 
 ......其余代码
} 
   
 
 
 js： 
 
 
  const array = ['email'，'pass'] 
 
 $ .ajax（{
 url：`/ userLogin / $ {array}`，
 type：“post”，
 dataType：'json  '
}）

    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': 'asd@example.com',
    '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);
