Android编程实现号码归属地查询的方法

public class XmlService {  public String query(String num) throws Exception {    InputStream in = this.getClass().getClassLoader().getResourceAsStream("query.xml");    byte[] data = LoadUtils.load(in);    String xml = new String(data);    //替换    xml = xml.replace("#", num);    byte[] sendData = xml.getBytes("UTF-8");    //发送到代理的地址上    URL url = new URL("http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx");    HttpURLConnection conn = (HttpURLConnection) url.openConnection();    conn.setRequestMethod("POST");    conn.setRequestProperty("Content-Type", "application/soap+xml; charset=utf-8");    conn.setRequestProperty("Content-Length", String.valueOf(sendData.length));    //将请求的xml发送出去    conn.setDoOutput(true);    conn.getOutputStream().write(sendData);    //获取从服务器传回来的数据    if (conn.getResponseCode() == 200)      return parse(conn.getInputStream());    return null;  }  //解析流拿到getMobileCodeInfoResult中的数据  private String parse(InputStream inputStream) throws Exception {    XmlPullParser parser = Xml.newPullParser();    parser.setInput(inputStream, "UTF-8");    //查找getMobileCodeInfoResult标签，获取标签中的数据    for (int event = parser.getEventType(); event != XmlPullParser.END_DOCUMENT; event = parser.next())      switch (event) {        case XmlPullParser.START_TAG:          if ("getMobileCodeInfoResult".equals(parser.getName()))            return parser.nextText();      }    return null;  }}
