无法刷新我的access_token

Question

I've been trying for hours to get a new access token from the Google API but it kept throwing me a 400 error : bad request. Any idea ?

r = RestClient.post 'https://accounts.google.com/o/oauth2/token', :refresh_token => refresh_token, :client_id => client_id, :client_secret => client_secret, :grant_type => 'access_token'

EDIT : Do I need to force content-type ? Do you have an alternative solution to RestClient ?

Answer 1

grant_type should be " refresh_token " and not " access_token "

Try this:

RestClient.post 'https://accounts.google.com/o/oauth2/token', :refresh_token => refresh_token, :client_id => client_id, :client_secret => client_secret, :grant_type => 'refresh_token'
