NAME

LWP::Authen::OAuth2::AccessToken - Access tokens for OAuth2.

VERSION

version 0.18

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!
