Good day everyone!
I'm trying to integrate the gdata service into my app
I've followed this tutorial
https://developers.google.com/appengine/articles/gdata
the step1~3 is created by copy & paste, and a step4, which is a snippet
that I found somewhere else
> class step4(webapp.RequestHandler):
> def get(self):
> # Create a client class which will make HTTP requests with Google Docs
> server.
> client = gdata.docs.service.DocsService()
> # Authenticate using your Google Docs email address and password.
> client.ClientLogin('usern...@gmail.com', 'pass')
> # Query the server for an Atom feed containing a list of your documents.
> documents_feed = client.GetDocumentListFeed()
> # Loop through the feed and extract each document entry.
> for document_entry in documents_feed.entry:
> # Display the title of the document on the command line.
> print document_entry.title.text
the step4 worked fine locally, but I couldn't figured out what step3 is
about. so, I think maybe I'll need to upload to the server.
during the uploading, I've noticed the messages regarding to the ssl
thingy. and so I installed the pre-compiled ssl-1.15.win32-py2.5.exe that I
found on the web.
the ssl message is gone during the re-upload.
after some more digging, I had managed to pull out the feeds from the
Google services using step3.
I was happy! went to bed, woke up, had a lovely meal then booted up my
computer.
all the sudden the step4 locally, had stopped working.
the traceback looks like this

and here's the traceback from step3

they seem to be caused by the same problem.
I've Googled here and there for like 5 hours.
and heard people talking about setting the fetch()'s validate_certificate
variable to False, instead of None
> fetch(url, payload=None, method=GET, headers={}, allow_truncated=False,
> follow_redirects=True, deadline=None, validate_certificate=None)
Since I'm not using the fetch() directly and the function is in the
appengine's api.
changing the source code probably won't do anything.
is there's any workaround?
also I'm suspicious about the SSL... maybe the ssl library is what's
causing this?
