Re: Transferring open-Id Info to Google apps script through CURL to run app script in the background

Stephen,

cURL acts 'like' a browser, in that it sends & receives POST & GET requests and manages the cookies associated. To accomplish what you want, you'll need to research the HTTP Headers and then set-up the curlopts to mimic the real requests. 

If you don't already have access to the header info, I suggest using LiveHTTPHeaders (a Firefox plugin) or Chrome's developer window to log requests (persistent logging is helpful) via a 'real' login. Then build step-by-step, a script to store cookies and perform the login. Those cookies are most likely needed for subsequent requests to verify access. 

In essence, you'll call curl_exec($ch) several times and will modify the behavior, for instance: POST/GET, post data, target & referrer, along with possibly capturing some values from $returndata after each. The header info log from above will help you build this list of pages to request by script.

Because a login is involved, this will likely take some time and further learning about cURL. It will likely also increase the length of your script!

This is a good board for more specific questions.
