DESCRIPTION

Provides a way to authenticate with a CAS server just as a browser would. This is useful with web scrapers needing to login to a CAS site.

ROLE REQUIRES

This is a Moose::Role and for this role to be used, the user MUST provide the following two methods:

get_cas_credentials

This is called as a method with the first argument being a string that is the URL of the service that is about to be logged in to. If no service is being logged in to, then it will be undefined. This function is expected to return a username string and a password string, both of which are optional, but MUST be returned in that order.

This is called as a method with the first argument being a string that is the username being used and the second argument being a string that is the URL of the service that is about to be logged into. This function is expected to return a string that is the ticket granting cookie for the CAS service, or nothing.

ATTRIBUTES

cas_url

This is a URI object of the base URL of the CAS site. This is typically the path before /login. A string may be supplied and will automatically be converted to a URI object.

previous_response

This holds the response object Authen::CAS::External::Response from the last executed CAS navigation.

redirect_back

This is a Boolean that determines if the "user_agent" will navigate outside of the "cas_url". The default is 0.

user_agent

This is a LWP::UserAgent that is used to navigate the CAS site. The default is LWP::UserAgent with an in-memory cookie jar and allows the POST method to be redirectable.

METHODS

clear_previous_response

This will clear the "previous_response" attribute.

get

This is an alias to the get method of the "user_agent".

has_previous_response

This will return if there is a value present in the "previous_response" attribute.

service_request_url

service_request_url(%args)

This method will return a URI object that is the URL to request for the CAS login page. All arguments are optional. The following are the possible arguments:

  • cas_url

    Added in version 0.06; be sure to require this version for this feature.

    This is the URL of the CAS deployment to use. By default this will use the "cas_url" attribute. This can be either a URI object or a string.

  • service

    This is a string of the service URL to log in to.

  • gateway

    This is a Boolean of whether or not to use gateway login mode.

  • renew

    This is a Boolean to whether or not to renew the session.
