Get user profile

[SimonLab]

Google Plus API is now deprecated:

After a while trying to find the documenatation I think the new endpoint to get the user profile is:
https://www.googleapis.com/oauth2/v3/userinfo?access_token=...

You don't need to enable other API on the Google console.
I've manage to get my user info directly via the browser, however I've got some error while parsing the response with Poison (I thin the request returned an error).
I'm going to check if the request needs specific headers to work

Getting the user information:

The mix dependency wasn't up to date!

The information available are defined by the scopes which can be
profile returns family_name, given_name, name, picture, sub
email returns email, email_verified, picture, sub
openid returns picture, sub

(I've tested the returns value manually by inspecting the returned values so maybe more information can be displayed?)

see https://developers.google.com/identity/protocols/googlescopes#google_sign-in

You can combine scopes by adding space between them, for example if you want to get the profile information and the email information you can use the scope profile email.

The scope value is used to create the Google authentication url and will define which information will be accessible:

elixir-auth-google/lib/elixir_auth_google.ex

	def generate_oauth_url do
	client_id = Application.get_env(:elixir_auth_google, :google_client_id)
	scope = Application.get_env(:elixir_auth_google, :google_scope ) || "profile"
	redirect_uri = Application.get_env(:elixir_auth_google, :google_redirect_uri)
	"#{@google_auth_url}&client_id=#{client_id}&scope=#{scope}&redirect_uri=#{redirect_uri}"
