[groovy-user] HTTPBuilder and basic authentication.

I am trying to make use of the Groovy HTTPBuilder to handle some REST services which require basic authentication.

I can successfully use curl --basic to get a valid response.

When I follow the documentation for Groovy HTTPBuilder, http://groovy.codehaus.org/modules/http-builder/doc/auth.html, and specify the same username/password, the request fails.

The code looks like this (just like the documentation says)

restClient = new RESTClient("http://prodinfobuild.broadinstitute.org:8085/rest/api/latest/")

restClient.auth.basic 'mhusby', 'bamboo'

def response = restClient.get(path:'project')

I am using Groovy 1.7.2, HTTPBuilder 0.5.1 (the latest).

What am I overlooking?

The log output shows:

DEBUG - Receiving response: HTTP/1.1 401 Unauthorized

DEBUG - << HTTP/1.1 401 Unauthorized

Looks right so far, but you left out the critical part of debug info in your email -- the request! Can you send the log output of the preceding request? That should help troubleshooting.

Thanks.
