[google-appengine] Using AppCfg to update the app behind an authenticated proxy

[Piwaï]

Hello !

I have been looking through the web for quite some time, tried a lot
of things and didn't find any working solution to my problem, so I
wish someone here will have a solution for me :-) !

I am trying to deploy a GAE Java app, and I am going through a
corporate proxy, which requires authentication.

The proxy config looks like this :

user : DOMAIN\username
password : pass
http proxy : proxy_http.something.com:8000
https proxy : proxy_https.something.com:8000

I read this : http://code.google.com/appengine/docs/java/tools/uploadinganapp.html#Using_an_HTTP_Proxy

=> The values for --http_proxy and --proxy_https must match
"proxy_http.something.com:8000", and does not work when matching
"http://DOMAIN\username:pass@proxy_http.something.com:8000" =>
(unknown host)

I tried to set the proxy informations by modifying appcfg.cmd and
adding some java proxy arguments :

-Dhttp.proxyHost="http://DOMAIN
\username:pass@proxy_http.something.com" -Dhttp.proxyPort=8000
-Dhttps.proxyHost="http://DOMAIN
\username:pass@proxy_https.something.com" -Dhttps.proxyPort=8000

=> still unknown host error.

I also tried this :

-Dhttp.proxyHost="proxy_http.something.com" -Dhttp.proxyPort=8000
-Dhttp.proxyUser="DOMAIN\username" -Dhttp.proxyPassword=pass
-Dhttps.proxyHost="proxy_https.something.com" -Dhttps.proxyPort=8000
-Dhttps.proxyUser="DOMAIN\username" -Dhttps.proxyPassword=pass

The host is resolved but then it tries to use the proxy and gets an
Authentication failure exception.

Then I tried to call AppCfg.main myself, and the the proxy and Proxy
auth in the JVM prior to calling it :

public class Test {

public static void main(String[] args) {

Authenticator.setDefault(new ProxyAuthenticator("DOMAIN\
\username", "pass"));

System.setProperty("http.proxyHost",
"proxy_https.something.com");
System.setProperty("http.proxyPort", "8000");
System.setProperty("https.proxyHost",
"proxy_https.something.com");
System.setProperty("https.proxyPort", "8000");

String[] appArgs = { "update", "PATH TO MY WAR FOLDER" };

AppCfg.main(appArgs);
}

static class ProxyAuthenticator extends Authenticator {

private String user, password;

public ProxyAuthenticator(String user, String password) {
this.user = user;
this.password = password;
}

@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user,
password.toCharArray());
}
}

}

However, I still get the Authentication failure exception. Here is the
stacktrace :

Seems that GAE uses a
sun.net.www.protocol.https.HttpsURLConnectionImpl, and it doesn't seem
to take the Authenticator into account.

Has anyone already achieved to upload java gae applications through an
authenticated proxy ? Any hint would be great !

Also, are the sources available ? I might soon try to retro-engineer
the com.google.appengine.tools.admin classes to understand how it
deploys the whole stuff...

Cheers,
Piwaï

For the records : I have finally been able to deploy using a trick : I
used a local unauthenticated proxy to the corporate authenticated
proxy ;-) !

I installed "Charles Proxy", run it, configured the "External Proxy
Settings" part with my Auth informations. Then I configure appcfg
script to connect to the local proxy (localhost:8888). And voila, it
works !
