java 代码?

1. //?Query?the?server?and?retrieve?the?response.??
2. HttpConnection?hc=?(HttpConnection)Connector.open(url);??
3. InputStream?in?=?hc.openInputStream();??
4. ??
5. //?Read?the?session?ID?from?a?cookie?in?the?response?headers.??
6. String?cookie?=?hc.getHeaderField("Set-cookie");??
7. if?(cookie?!=?null)?{??
8. ??int?semicolon?=?cookie.indexOf(';');??
9. ??mSession?=?cookie.substring(0,?semicolon);??
10. }??
11. ??
12. //?Read?the?response?from?the?server.??
13. ??
14. //?Clean?up.??
15. in.close();??
16. hc.close();??

1. //?Query?the?server?and?retrieve?the?response.??

3. if?(mSession?!=?null)??

10. ??int?semicolon?=?cookie.indexOf(';');??
11. ??mSession?=?cookie.substring(0,?semicolon);??
12. }??
13. //?Read?the?response?from?the?server.??
14. //?Clean?up.??
15. in.close();??
