NAME
LWP::Authen::OAuth2::AccessToken - Access tokens for OAuth2.
VERSION
version 0.19
SYNOPSIS
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.
METHODS
from_ref
Construct an access token from a hash reference. The default implementation merely blesses it as an object, defaulting the create_time
field to the current time.
my $access_token = $class->from_ref($data);
If you roll your own, be aware that the fields refresh_token
and _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.
to_ref
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.
expires_time
Estimate expiration time. Not always correct, due to transit delays, clock skew, etc.
expires_in
Estimate the seconds until expiration. Not always correct, due to transit delays, clock skew, etc.
should_refresh
Boolean saying whether a refresh should be emitted now.
for_refresh
Returns key/value pairs for $oauth2
(and eventually the service provider class) to use in trying to refresh.
copy_refresh_from
Pass in a previous access token, copy anything needed to refresh.
request
Make a request. If expiration is detected, refreshing by the best available method (if any).
my $response = $access_token->request($oauth2, @request_for_lwp);
_request
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!
