java - 如何在后台线程中使用 HttpPost 执行 MultipartEntity？

Question

如何执行此代码以使其在后台线程中发送？

// TODO: Send image in background
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(urlString);

            try {
              MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
              entity.addPart("userfile", new FileBody(f));
              httppost.setEntity(entity);
              HttpResponse response = httpclient.execute(httppost);
              BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
              String sResponse;
              StringBuilder s = new StringBuilder();

              while ((sResponse = reader.readLine()) != null) {
                  s = s.append(sResponse); 
              }
              Log.d("Response", "Response: " + s);
            } 
            catch (ClientProtocolException e) {
            } 
            catch (IOException e) {
            }

与您在后台线程中执行任何操作的方式相同——启动一个线程来执行此操作。在 Android 上，您可以使用AsyncTask在后台执行内容并在完成后更新 UI。
