Question

private void login() {     new Thread(new Runnable() {         @Override         public void run() {             try {                 Response result = HttpUtil.sendOkHttpRequest(address);                 if (result != null) {                     String responseDta = Objects.requireNonNull(result.body()).string();                     JsonParser parser = new JsonParser();                     JsonObject jsonObject = parser.parse(responseDta).getAsJsonObject();                     JsonObject  msg = jsonObject.get("responseDta").getAsJsonObject();                     System.out.println(msg.get("responseDta"));                     //判断登录成功还是失败，并向主线程传递数据                     if ("success".equals(msg)) {                         Message message = new Message();                         message.what = 1;                         message.obj = msg;                         handler.sendMessage(message);                     } else {                         Message message = new Message();                         message.what = 2;                         message.obj = msg;                         handler.sendMessage(message);                     }                 }             } catch (IOException e) {                 e.printStackTrace();             }         }     }).start(); }
