示例代碼發送您的json到服務器並獲得響應（如果有）。

private Void sendJsonGetAsynch() { 
    Reader r; 
    HttpClient httpClient = ConnectionUtil.getNewHttpClient(); 
    HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), 10000); 
    HttpPost httpost = new HttpPost("your url"); 
    InputStream data = null; 
    try 
     String json = URLEncoder.encode("here goes your json string ", "UTF-8"); 
     StringEntity visitBeanStringEntity = new StringEntity(json); 
     httpost.setEntity(visitBeanStringEntity); 
     httpost.setHeader("json", "application/json"); 
     httpost.setHeader(HTTP.CONTENT_TYPE, "application/json"); 

     HttpResponse response = httpClient.execute(httpost); 
     if (response != null) { 

      data = response.getEntity().getContent(); 
      r = new InputStreamReader(data); 

      StringBuffer buffer = new StringBuffer(); 
      Reader in = new BufferedReader(r); 
      int ch; 
      while ((ch = in.read()) > -1) { 
       buffer.append((char) ch); 
      } 
      in.close(); 
      logger.info("Return :" + buffer.toString()); 
      return buffer.toString(); 
     } else { 
      logger.error("Response was null"); 
      throw new Exception("JSON response was null"); 
     } 
    } catch (Exception e) { 
     logger.error(e.getMessage()); 
    } 

}
