Send XML data to the Internet

Code:

1. Using the httpurlconnection object, we can send XML data to the network.
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/"> China </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); // allow output
12. Conn. setusecaches (false); // No cache is used.
13. Conn. setrequestmethod ("Post ");
14. Conn. setrequestproperty ("connection", "keep-alive"); // maintain a persistent connection
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); // send XML data
20. Outstream. Flush ();
21. If (conn. getresponsecode ()! = 200) throw new runtimeexception ("request URL failed ");
22. Inputstream is = conn. getinputstream (); // get the returned data
23. String result = readasstring (is, "UTF-8 ");
24. Outstream. Close ();
