（转）向Internet发送xml数据

Code:

1.  利用HttpURLConnection对象,我们可以向网络发送xml数据.  
2. StringBuilder xml =  new StringBuilder();  
3. xml.append("<?xml version=/"1.0/" encoding=/"utf-8/" ?>");  
4. xml.append("<M1 V=10000>");  
5. xml.append("<U I=1 D=/"N73/">中国</U>");  
6. xml.append("</M1>");  
7. byte[] xmlbyte = xml.toString().getBytes("UTF-8");  
8. URL url = new URL("http://localhost:8080/itcast/contanctmanage.do?method=readxml");  
9. HttpURLConnection conn = (HttpURLConnection) url.openConnection();  
10. conn.setConnectTimeout(6* 1000);  
11. conn.setDoOutput(true);//允许输出  
12. conn.setUseCaches(false);//不使用Cache  
13. conn.setRequestMethod("POST");          
14. conn.setRequestProperty("Connection", "Keep-Alive");//维持长连接  
15. conn.setRequestProperty("Charset", "UTF-8");  
16. conn.setRequestProperty("Content-Length", String.valueOf(xmlbyte.length));  
17. conn.setRequestProperty("Content-Type", "text/xml; charset=UTF-8");  
18. DataOutputStream outStream = new DataOutputStream(conn.getOutputStream());  
19. outStream.write(xmlbyte);//发送xml数据  
20. outStream.flush();  
21. if (conn.getResponseCode() != 200) throw new RuntimeException("请求url失败");  
22. InputStream is = conn.getInputStream();//获取返回数据  
23. String result = readAsString(is, "UTF-8");  
24. outStream.close();
