Google Data API Client Libraries with proxy

问题

I use java and gdata API to manage my Calendar's data. But it works only if I have direct access to the Internet. In my case I have to use proxy. Is there any way to manage my Google calendar's data through the proxy?

I'v tried this way:

System.setProperty("http.proxyHost", "myproxy.mydomain.com");
System.setProperty("http.proxyPort", "3128");
URL feedUrl = new URL("http://www.google.com/calendar/feeds/....");
CalendarService myService = new CalendarService("exampleCo-exampleApp-1");      

String encoded = new String(Base64.encodeBase64(new String("proxy_user:proxy_password").getBytes()));
String base64encodedCredentials = "Basic " + encoded;
myService.getRequestFactory().setPrivateHeader("Proxy-Authorization", base64encodedCredentials);

//!!! Exception in this line
myService.setUserCredentials("my_google_accaunt@gmail.com", "my_google_password");

Exception:

Exception in thread "main" com.google.gdata.util.AuthenticationException: Error connecting with login URI

Without proxy everything works.

You didn't say what language you're using but instructions for Java and .Net# are at:

https://developers.google.com/gdata/articles/proxy_setup

instructions for Python can be found at:

http://code.google.com/p/gdatacopier/wiki/ProxySupport (these should work for any app using the gdata-python-client)
