How to post array parameters with Retrofit?

Question

I want to post data as follows:

   {
     "user_id":"14545646",
    "list":["4545645","4545645","4545645","4545645"]
   }

I used the following Retrofit method:

interface DeleteOrder {

         @FormUrlEncoded
         @POST("/api/shop/deleteOrder.json")
         void getPoJoDeleteOrder(@Field("user_id") String user_id, @Field("list") String[] list,Callback<PoJoDeleteOrder> callback);

      }

Is this the correct way?

Answer 1

if have many user,then use FieldMap.

user[0][email]=&user[0][password]=&user[1][email]=&user[1][password]=

@POST("/user/sign_in")

User login(@FieldMap Map<String,String> fields);

    Map<String,String> fields = new HashMap<>();
    for (int i=0;i<users.size();i++) {
        User user= users.get(i);
        fields.put("user["+i+"][email]",user.email);
        fields.put("user["+i+"][password]",user.password);
    }
