调用webservice查询手机号码归属地信息

Web Services是由企业发布的完成其特定商务需求的在线应用服务，其他公司或应用软件能够通过Internet来访问并使用这项在线服务。在这里我们使用soap协议往webservice发送信息，然后得到webservice服务器返回过来的信息，以此来查询手机号码的归属地信息。

Web Services有很多服务提供商，在这里我们使用www.webxml.com.cn的，如图：

点击进去，我们可以看到soap协议定义的内容。

接下来就是编写代码了。

package cn.mzba.service;

 

import java.io.InputStream;

import java.io.OutputStream;

import java.net.HttpURLConnection;

import java.net.URL;

import org.xmlpull.v1.XmlPullParser;

import android.util.Xml;

 

public class MobileService {

 

    public static String findAddress(String mobile) throws Exception {

        InputStream is = MobileService.class.getClassLoader()

                .getResourceAsStream("mobilesoap.xml");

        byte[] data = StreamTool.readStream(is);

        String xml = new String(data, "UTF-8");

        String soap = xml.replaceAll("\\$mobile", mobile);

        byte[] result = soap.getBytes("UTF-8");

        String path = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";

        URL url = new URL(path);

        HttpURLConnection conn = (HttpURLConnection) url.openConnection();

        conn.setRequestMethod("POST");

        conn.setDoOutput(true);

        conn.setConnectTimeout(5 * 1000);

 

        conn.setRequestProperty("Content-Type",

                "application/soap+xml; charset=utf-8");

        conn.setRequestProperty("Content-Length", String.valueOf(result.length));

        OutputStream os = conn.getOutputStream();

        os.write(result);

        os.flush();

        os.close();

 

        InputStream isSocp = conn.getInputStream();

        return parse(isSocp);

    }

 

    public static String parse(InputStream is) throws Exception {

        XmlPullParser parser = Xml.newPullParser();

        parser.setInput(is, "UTF-8");

        int event = parser.getEventType();

        while (event != XmlPullParser.END_DOCUMENT) {

            switch (event) {

            case XmlPullParser.START_TAG:

                if ("getMobileCodeInfoResult".equals(parser.getName())) {

                    return parser.nextText();

                }

                break;

            }

            event = parser.next();

        }

        return null;

    }

}

package cn.mzba.service;

 

import java.io.ByteArrayOutputStream;

import java.io.InputStream;

 

public class StreamTool {

    /**

     * 读取输入流数据

     *

     */

 

    public static byte[] readStream(InputStream is) throws Exception {

        ByteArrayOutputStream os = new ByteArrayOutputStream();

        byte[] buffer = new byte[2048];

        int len = 0;

        while ((len = is.read(buffer)) != -1) {

            os.write(buffer, 0, len);

        }

        is.close();

        return os.toByteArray();

    }
