示例代碼：

 try { 
      URL object = new URL(url); 
      HttpURLConnection con = (HttpURLConnection) object.openConnection(); 
      con.setDoOutput(true); 
      con.setDoInput(true); 
      con.setRequestProperty("Content-Type", "application/json; charset=utf-8"); 
      con.setRequestProperty("Accept", "application/json; charset=utf-8"); 
      con.setRequestMethod("POST"); 
      OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream()); 
      wr.write(json); 
      wr.flush(); 
      InputStream inputStream = con.getInputStream(); 
      BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream)); 
      String line = ""; 
      while ((line=reader.readLine()) != null) { 
       response += "\n" + line; 
      }
