问题
I'm using Google's OAuth2 API in a project, using Omniauth to enable creating the initial accounts with little effort, but in order to use the APIs I need to refresh the access_token since they're only valid for an hour, but I'm having an issue updating the expires_at value when I refresh the token.
Here's the code I'm using for requesting the token refresh:
require 'oauth2'
class Identity < ActiveRecord::Base
belongs_to :user
def refresh_access_token
case self.provider
when "google"
client = OAuth2::Client.new OAUTH_KEYS_CONFIG['google']['client_id'],
OAUTH_KEYS_CONFIG['google']['client_secret'],
{
:site => 'https://accounts.google.com',
:authorize_url => "/o/oauth2/auth",
:token_url => "/o/oauth2/token"
}
response = OAuth2::AccessToken.from_hash(client, :refresh_token => self.refresh_token).refresh!
self.update_attribute(:access_token, response.token)
self.update_attribute(:expires_at, Time.at(response.expires_at))
end
end
end
I get an undefined method 'change' for 1359936923:Fixnum error on the final update_attribute line for :expires_at (I split it from the line above to try and figure out the issue).
I've tried both the above update_attribute call, and also a simple self.expires_at = response.expires_at, with and without Time.at casting but all combinations result in the same error.
The :expires_at attribute is a Timestamp datatype. I've checked the response variable, it contains the timestamp correctly as far as I can tell:
--- !ruby/object:OAuth2::AccessToken
...
expires_in: 3600
expires_at: 1360019618
options:
:mode: :header
:header_format: Bearer %s
:param_name: bearer_token

回答1:
If you can get away with it, you can turn off time zone awareness for your attribute, expires_at.
class Identity < ActiveRecord::Base
self.skip_time_zone_conversion_for_attributes = [:expires_at]
end
We are seeing the same issue because we have a Android app sending an Epoch time back to our website. Turning off time zone conversion for that attribute got rid of the error and so far seems to have no ill effects on the data. Of course, we're storing everything in UTC and so far this seems to be the only work around.
