调用webservice查询手机号归属地信息

 

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。

Web Services有很多种类型，在这里我们使用www.webxml.com.cn。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
	 * @param is
	 * @return
	 * @throws Exception
	 */
	
	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();
	}
