使用auth令牌的JAVA rest获取请求

我正在尝试使用auth令牌创建post请求，但得到的响应为空。你能帮我一下吗？你能告诉我我在代码中遗漏了什么吗

public static void main(String[] args) {
         try {
                String url = "https://test.abc.com/";
                    String token="XXXXXX-abcd-496a-ae73-7659587896";
                URL object = new URL(url);
                HttpURLConnection con = (HttpURLConnection) object.openConnection();
                con.setDoInput(true);
                con.setRequestMethod("GET");
                con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
                con.setRequestProperty("Accept", "application/json");
                con.setRequestProperty("Authorization", "Bearer " + token);
                //Display what the GET request returns
                StringBuilder sb = new StringBuilder();
                int HttpResult = con.getResponseCode();
                if (HttpResult == HttpURLConnection.HTTP_OK) {
                    BufferedReader br = new BufferedReader(
                            new InputStreamReader(con.getInputStream(), "utf-8"));
                    String line = null;
                    while ((line = br.readLine()) != null) {
                        sb.append(line + "\n");
                    }
                    br.close();
                    System.out.println(con.getResponseMessage());
                } else {
                    System.out.println(con.getResponseMessage());
                }
            } catch (Exception e) {
                System.out.println(e);
            }
         }
    }

你能添加错误堆栈跟踪吗？调试你的代码你会发现一个错误，说明为什么你的数据为空。或者您可以给出响应代码或错误堆栈，这样我们就可以很容易地找到问题。它是空的
