最近在学习Web Service发现了个国内Web Service提供站点其中最简单是查询QQ在线状态服务我通过Java直接发送SOAP请求文件访问Web Service成功这种方式实现比较简单不需要第 3方软件Software包

import java.io.*;
import java.net.*;

QQOnlineService {
    public void (String args) throws Exception {
        String urlString = "http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx";
        String xmlFile = "QQOnlineService.XML";
        String soapActionString = "http://WebXml.com.cn/qqCheckOnline";

        URL url = URL(urlString);

        HttpURLConnection httpConn = (HttpURLConnection) url.openConnection;;

        File fileToSend= File(xmlFile);
        buf= [()fileToSend.length];
        FileInputStream(xmlFile).read(buf);
        httpConn.RequestProperty( "Content-Length",String.valueOf( buf.length ) );
        httpConn.RequestProperty("Content-Type","text/xml; char=utf-8");
        httpConn.RequestProperty("soapActionString",soapActionString);
        httpConn.RequestMethod( "POST" );
        httpConn.DoOutput(true);
        httpConn.DoInput(true);
        OutputStream out = httpConn.getOutputStream;
        out.write( buf );
        out.close;
       
        InputStreamReader isr = InputStreamReader(httpConn.getInputStream,"utf-8");
        BufferedReader in = BufferedReader(isr);
       
        String inputLine;
        BufferedWriter bw= BufferedWriter( OutputStreamWriter( FileOutputStream("result.xml")));
        while ((inputLine = in.readLine) != null){
            .out.prln(inputLine);
            bw.write(inputLine);
            bw.Line;
        }
        bw.close;
        in.close;
    }
}
用到 QQOnlineService.XML文件可以通过预先访问http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx得到

查询结果文件如下对其进步编程可以实现更为灵活查询功能
