Question

我在android中的HttpURLConnection中有500个响应代码。我从api调用中获取了一些数据。我无法找到问题。我搜索了很多并尝试过我自己但没有得到任何帮助。我在其他文件中有这样的代码并且它们运行良好。没有错误消息或异常。 这是我的代码段。

private void sendOfferAccepted(String  reqirement_id, final Context contex, String offer_id,String buyer_id, String status) {


        class HttpPost extends
                AsyncTask<Void, Void, String> {

            String mess = contex.getResources().getString(R.string.server_ip_api);

            String urlString = "https://"+mess+"/api/v1/accept_reject_supplier_offer/";

            private final String TAG = "post json example";

            private Context context;

            ProgressDialog progDailog = new ProgressDialog(contex);

            public HttpPost(String reqirement_id, final Context contex, String offer_id, String status) {


                this.context = contex;
