Hi all,
I've been trying to insert items in a Google Base from a web
application written for Google Apps Engine but I'm not able to, due to
problems with authentication. I'm using gdata-py-1.2.4 and GAE SDK
1.1.9.
Here is a sample code of what I do:
class MainPage(webapp.RequestHandler):
def get(self):
next_url = atom.url.Url('http', settings.HOST_NAME, path='/
doit')
client = gdata.base.service.GBaseService()
gdata.alt.appengine.run_on_appengine(client)
get_token = client.GenerateAuthSubURL(next_url,
('http://www.google.com/base/',), secure= False,
session=True)
self.response.out.write("""<html><body>
<a href="%s">Request token for the Google Base Scope</a>
</body></html>""" % get_token)
class DoIt(webapp.RequestHandler):
def get(self):
client = gdata.base.service.GBaseService()
gdata.alt.appengine.run_on_appengine(client)
auth_token = gdata.auth.extract_auth_sub_token_from_url
(self.request.uri)
session_token = client.upgrade_to_session_token(auth_token)
client.current_token = session_token
item = gdata.base.GBaseItem()
item.author.append(atom.Author(name=atom.Name(text='Mr.
Smith')))
item.title = atom.Title(text='He Jingxian\'s chicken')
item.link.append(atom.Link(rel='alternate', link_type='text/
html',href='http://www.host.com/123456jsh9'))
item.label.append(gdata.base.Label(text='kung pao chicken'))
item.item_type = gdata.base.ItemType(text='recipes')
item.AddItemAttribute(name='cooking_time', value='30 minutes')
item.AddItemAttribute(name='main_ingredient', value='chicken')
client.InsertItem(item)
application = webapp.WSGIApplication([("/",MainPage),('/doit',DoIt)])
def main():
run_wsgi_app(application)
if __name__ == '__main__':
main()
No matter what scope I specify in GenerateAuthSubURL(tried with
http://www.google.com/base http://www.google.com/base/feeds
http://www.google.com/base/feeds/items http://base.google.com/ and so
on) when i try to insert an item by GETting /doit I get the following
output in the console running the development web server:

confused :)
Thanks in Advance!
