I successfully receive an authorization token from google, but when I try to get the access token, I get an invalid_request.

Our first attempt in PHP resulted in that response, when I tried it through my HTTP client, I get the same. Finally, I tried directly with CURL and still got the same results:

curl -v -k --header "Content-Type: application/x-www-form-urlencoded" \
-F 'code=4/U2su0fwiynq4v8J8xD56ohfF0fX6.EhP0brx3cosbuJJVnL49Cc8EFE7ncQI' \
-F 'client_id=012345678901-abcdefghijklmnopqrstuvwxyz012345.apps.googleusercontent.com' \
-F 'client_secret=ABC123ABC123ABC123ABC123' \
-F 'grant_type=authorization_code' \
-F 'redirect_uri=https://app.myserver.com/googleLogin.php' \
https://accounts.google.com/o/oauth2/token

The response I receive is:

I’m not url-encoding anything before I send it, but when I do, I get the same result.

Any help is greatly appreciated!
