如何从json响应访问member_id？

{
  "status": "success",
  "data": {
    "user": {
      "member_id": "123456"
    }
  }
}

let jsonResponse = '{"status":"success","data":{"user":{"member_id":"123456"}}}';
let obj = JSON.parse(jsonResponse);

let memberId = obj.data.user.member_id;
console.log(memberId); // 输出: 123456

import json

json_response = '{"status":"success","data":{"user":{"member_id":"123456"}}}'
obj = json.loads(json_response)

member_id = obj['data']['user']['member_id']
print(member_id)  # 输出: 123456

import org.json.JSONObject;

public class Main {
    public static void main(String[] args) {
        String jsonResponse = "{\"status\":\"success\",\"data\":{\"user\":{\"member_id\":\"123456\"}}}";
        JSONObject obj = new JSONObject(jsonResponse);

        String memberId = obj.getJSONObject("data").getJSONObject("user").getString("member_id");
        System.out.println(memberId); // 输出: 123456
    }
}
