Below is documentation on how to access Google+ resources. It's based on the access patterns of the browser.
What you should be impressed most about this API is how large some of these
data objects are. For instance, the Item object below which represents an
item in your stream has 23 documented fields while the Google code
has room for 91 fields. Who knows what they have in store for us next.
Authentication is performed by simply POSTing your credentials to a service and tracking cookies. To kick it off, grab some cookies from:
1.1 GET http://plus.google.com
We do this just to collect some cookies and the gpcaz variable in the response URL.
1.2 GET https://www.google.com/accounts/ServiceLogin?service=oz&continue=https://plus.google.com/?gpcaz%3DXXXXXXXX<mpl=es2st&hideNewAccountLink=1&hl=en-US
We need some more cookies; specifically, GALX which gets set thanks to this call. You will need to substitute gpcaz with the one you got from 1.1.
We pass our credentials to this service to authenticate.

On a successful POST, you will get back the G+ home page. That page contains a lot of
JavaScript data in <script> tags. The next section covers some of that data.
Every Item has an ItemType which can be one of:
- Photos Photos and Profile Photos
- Buzz Text Post
