获取ruby中的oauth2 access_token所有者电子邮件地址？

Question

I am successfully using Oauth2 gem to get an access tokens from Google accounts. But I want to get the email address which produced the token (I mean if I used this account "myemail@gmail.com" to get the access_token, how can I know the email address from the token?). Or can I get the email while obtaining the token?

Answer 1

Usually you can get that email with the response for any API call. For contacts API, by example, there is an entry called author in the response: https://developers.google.com/google-apps/contacts/v3/#retrieving_all_contacts

Anyway, I'm not sure which gem you're using. You can use oauth2 , doorkeeper or cloudsponge .
