HTTP 502

Question

尝试使用以下代码在我的客户端（Android应用程序）端运行httppost时，但在我的浏览器上，我确实只收到预期数据的JSON输出。

protected String doInBackground(String... params) {
                DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());
                HttpPost httppost = new HttpPost("http://192.168.43.229/thecee/mobile_app/the_lost.php");
                // Depends on your web service
              httppost.setHeader("Content-type", "application/json");

                InputStream inputStream = null;
                String result = null;
                try {
                    HttpResponse response = httpclient.execute(httppost);
                    HttpEntity entity = response.getEntity();
                    inputStream = entity.getContent();
                    // json is UTF-8 by default

                    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
                   StringBuilder sb = new StringBuilder();

                    String line = null;
                   while ((line = reader.readLine()) != null)
                    {
                        sb.append(line + "\n");
                        }
                   result = sb.toString();
                    Log.d("The Content", result);
                    } catch (Exception e) {
                    // Oops
                    }
                finally{
                    try {
                        if (inputStream != null) inputStream.close();
                    } catch (Exception squish) {
                    }
                    }
                return result;
               }

我在尝试解析时收到以下错误消息。
