LWP::Authen::OAuth2::AccessToken - Access tokens for OAuth 2.
This is a base class for signing API requests with OAuth2 access tokens.
A subclass should override the
request method with something that knows how to make a request,
detect the need to try to refresh,
and attmpts to do that.
See lWP::Authen::OAuth2::AccessToken::Bearer for an example.
Subclasses of this one are not directly useful. Please see LWP::Authen::OAuth2 for the interface that you should be using.
Construct an access token from a hash reference.
The default implementation merely blesses it as an object,
create_time field to the current time.
my $access_token = $class->from_ref($data);
If you roll your own, be aware that the fields
_class get used for purposes out of this class' control. Any other fields may be used. Please die fatally if you cannot construct an object.
Construct an unblessed data structure to represent the object that can be serialized as JSON. The default implementation just creates a shallow copy and assumes there are no blessed subobjects.
Estimate the seconds until expiration. Not always correct, due to transit delays, clock skew, etc.
Boolean saying whether a refresh should be emitted now.
Returns key/value pairs for
$oauth2 (and eventually the service provider class) to use in trying to refresh.
Pass in a previous access token, copy anything needed to refresh.
Make a request. If expiration is detected, refreshing by the best available method (if any).
my $response = $access_token->request($oauth2, @request_for_lwp);
Make a request with no retry logic, and return a response, and a flag for whether it is possible the access token is expired..
my ($response, $try_refresh) = $access_token->_request($oauth2, @request_for_lwp);
THIS IS THE ONLY METHOD A SUBCLASS MUST OVERRIDE!

We should support more kinds of access tokens.
Thanks to Rent.com for their generous support in letting me develop and release this module. My thanks also to Nick Wellnhofer <email@example.com> for Net::Google::Analytics::OAuth2 which was very enlightening while I was trying to figure out the details of how to connect to Google with OAuth2.
