			String httpurl;
			 Message message = new Message();

				HttpGet get=new HttpGet(httpurl);  
		        HttpClient client=new DefaultHttpClient();  
				try {  
		            HttpResponse response = client.execute(get);//執行get方法提交   
		            String retSrc = EntityUtils.toString(response.getEntity());//讀取返回數據  
		            JSONObject result = new JSONObject( retSrc);//通過JSON解析
