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?
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);
}
This way it will send arguments like this
project_id=986&remark=testing&details=detail_1....
If you want to send array in JSON format, you need to add [] to array name.
@FormUrlEncoded
@POST("/api/projectLost")
public void projectMarkLost(
@Field("project_id") int projectId,
@Field("lost_project_reasons[]") ArrayList<Integer> lostProjectReasons,
Callback<JsonObject> cb
);
That way you can check the array parameter with is_array($arr) and then iterate it. Source link.
If the list of query parameters is fixed you can do this:
@POST("/user/sign_in")
User login(
@Query("user[email]") String email,
@Query("user[password]") String password);
Otherwise, with the map you'll need to set the full query parameter as the key:
values.put("user[email]", "[email protected]");
values.put("user[password]", "123456");
