本文提供了一个使用Java通过HTTP POST请求查询QQ在线状态的示例代码。该示例利用了webxml提供的Web服务接口，并详细展示了如何构造SOAP消息、设置HTTP请求头及读取响应结果。

 

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

public	class QQOperator {
	    public static void main(String[] args) throws Exception {
	        String urlString = "http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx";
	        String xmlFile = "d:/qqOnlineWebService.xml";
	        String soapActionString = "http://WebXml.com.cn/qqCheckOnline";

	        URL url = new URL(urlString);

	        HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();;
	        System.out.println("start connect..");
	        File fileToSend=new File(xmlFile);
	        byte[] buf=new byte[(int)fileToSend.length()];
	        new FileInputStream(xmlFile).read(buf);
	        httpConn.setRequestProperty( "Content-Length",String.valueOf( buf.length ) );
	        httpConn.setRequestProperty("Content-Type","text/xml; charset=utf-8");
	        httpConn.setRequestProperty("soapActionString",soapActionString);
	        httpConn.setRequestMethod( "POST" );
	        httpConn.setDoOutput(true);
	        httpConn.setDoInput(true);
	        OutputStream out = httpConn.getOutputStream();
	        System.out.println("start connect 2..");
	        out.write( buf ); 
	        out.close();
	        
	        InputStreamReader isr = new InputStreamReader(httpConn.getInputStream(),"utf-8");
	        System.out.println("start connect 3..");

	        BufferedReader in = new BufferedReader(isr);
	        
	        String inputLine;
	        BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(new FileOutputStream("d:/result.xml")));
	        while ((inputLine = in.readLine()) != null){
	            System.out.println(inputLine);
	            bw.write(inputLine);
	            bw.newLine();
	        }
	        bw.close();
	        in.close();
	    }
	}

d:/qqOnlineWebService.xml内容如下：

<?xml version="1.0" encoding="utf-8"?>

    </qqCheckOnline>
