Subject: Question about Mechanize and Google API

Hi,

I'm trying to use Mechanize to retrieve spreadsheets from Google Docs
using the Google API. So far I got the ClientLogin to work, but I
can't seem to be able to use the Auth token they give me back. This is
what I have:

require 'logger'
require 'mechanize'

agent = WWW::Mechanize.new {|a| a.log = Logger.new("test.log")}
response = agent.post("https://www.google.com/accounts/ClientLogin",
"Email" => "xxx@gmail.com", "Passwd" => "xxxxx", "service" => "wise",
"source" => "personal-test-1.0", "accountType" => "GOOGLE")
h = {}
response.body.each {|line| a = line.split("="); h[a[0]] = a[1]}
auth = h["Auth"]
agent.basic_auth("GoogleLogin", auth)
# this didn't work either
#agent.auth("GoogleLogin", auth)
page = agent.get("http://spreadsheets.google.com/feeds/spreadsheets/private/full")

The problem is, according to google I have to:
"After a successful authentication request, use the Auth value to
create an Authorization header for each request:

Authorization: GoogleLogin auth=yourAuthValue"

I've checked and the ClientLogin is working and returning me an Auth
token, but I can't get Mechanize to use it. In the Mechanize logs I
see this:

So, it seems that the credentials are not correctly set. Anybody knows
how to do this?

Thanks,

Jesus.
