获取*归属地（转）

转载自原文http://www.oschina.net/question/565065_67907

 发送XML

 通过URL封装路径打开一个HttpURLConnection

 设置请求方式，Content-Type和Content-Length

XML文件的Content-Type为：text/xml; charset=UTF-8

使用HttpURLConnection获取输出流输出数据

 

 WebService

 WebService是发布在网络上的API，可以通过发送XML调用，WebService返回结果也是XML数据

 WebService没有语言限制，只要可以发送XML数据和接收XML数据即可

 http://www.webxml.com.cn 网站上提供了一些WebService服务，我们可以对其进行调用

 http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?op=getMobileCodeInfo 中提供了电话归属地查询的使用说明

内容如下：
