[wp-hackers] wp_remote_get() fails but wget works?

[Kurt Payne]

I never did get this to work. :-/

This is bouncing you from the spreadsheet to the login page, then back.
 Their login page must be looking for something more than just a cookie.

I did find a few things to help get you further, though.

First, the WordPress HTTP API can handle cookies.  It just doesn't do so by
default.  The code says so:

// Cookies are not handled by the HTTP API currently. Allow for plugin
authors to handle it
// themselves... Although, it is somewhat pointless without some reference.

I have some sample code up that should work (dd32 will correct me otherwise
:-)).  It's PHP 5.3 (beware the closure)
https://gist.github.com/kurtpayne/4724289

If you remove the unlink call, you can inspect the cookie file afterwards
and verify that the proper cookies were set.

Second, google has published an article on using curl to access spreadsheet
data.  It's got some specialized authentication tokens, but it may be
appropriate to your needs:
https://developers.google.com/gdata/articles/using_cURL

Last, this plugin claims do what you're after
http://wordpress.org/extend/plugins/wpgform/

But it comes with this caveat: "Currently, this plugin only supports Google
Forms that are "Published as a web page" and therefore public. Private
Google Forms are not supported."  So it may be a known issue.

I hope this helps!
