Question

我的控制器中有一个函数，该函数将数组作为输入。该值从ajax传递。目前无法正确解码。

removeItem = (title, body){

let myArray = [
  { title : 'title 1', body: 'body of title one' },
  { title : 'title 2', body: 'body of title two' },
  { title : 'title 3', body: 'body of title three' },
]

//the problem is down here
let filteredArray = myArray.filter(item => {
  item.title != title || item.body != body
}
  
// at this point i assume that the filtered array will not
// include the item that i want to remove
// so down here i reset the value of my original array to the filtered one
 
myArray = filteredArray

js：

 /**
 * @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
}

使用Request组件Symfony\Component\HttpFoundation\Request，您可以自动为其接线：public function userLogin(UserdbRepository $repository, Request $request)

示例1：从requestBody获取参数：

$email = $request->request->get('email', null); 如果请求中未提供$email参数，则null将是'email'

不要忘记在ajax请求中传递data属性

const requestBody = {
    'email': 'asd@example.com',
    'pass': '123',
};

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

注意：请勿以json格式发送数据。您也可以从@Route模式和$params参数中删除{params}。

示例2：从'email'获取queryString参数：

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

如何在symfony路由中传递Array？
