Member Function Documentation

virtual void shibsp::AbstractHandler::checkError	(	const xmltooling::XMLObject *	response,
		const opensaml::saml2md::RoleDescriptor *	role = `nullptr`
	)		const

protectedvirtual

Examines a protocol response message for errors and raises an annotated exception if an error is found.

The base class version understands SAML 1.x and SAML 2.0 responses.

Parameters

response	a response message of some known protocol
role	issuer of message

void shibsp::AbstractHandler::fillStatus	(	opensaml::saml2p::StatusResponseType &	response,
		const XMLCh *	code,
		const XMLCh *	subcode = `nullptr`,
		const char *	msg = `nullptr`
	)		const

protected

Prepares Status information in a SAML 2.0 response.

Parameters

response	SAML 2.0 response message
code	SAML status code
subcode	optional SAML substatus code
msg	optional message to pass back

		const xmltooling::HTTPRequest &	request,
		unsigned int	type = `HANDLER_PROPERTY_ALL`
	)		const

protected

Returns a boolean-valued property.

Parameters

name	property name
request	reference to incoming request
type	bitmask of property sources to use

Reimplemented from shibsp::Handler.

virtual void shibsp::AbstractHandler::preservePostData	(	const Application &	application,
		const xmltooling::HTTPRequest &	request,

	)		const

protectedvirtual

Implements a mechanism to preserve form post data.

Parameters

request	incoming HTTP request
response	outgoing HTTP response
relayState	relay state information attached to current sequence, if any

		const xmltooling::HTTPRequest &	request,
		xmltooling::HTTPResponse &	response,
		const char *	relayState
	)		const

protectedvirtual

Implements storage service and cookie mechanism to recover PostData.

If a supported mechanism can be identified, the return value will be the recovered state information.

Parameters

application	the associated Application
request	incoming HTTP request
response	outgoing HTTP response
relayState	relay state information attached to current sequence, if any

Returns: recovered form post data associated with request as a DDF list of string members

long shibsp::AbstractHandler::sendMessage	(	const opensaml::MessageEncoder &	encoder,
		xmltooling::XMLObject *	msg,
		const char *	relayState,
		const char *	destination,
		const opensaml::saml2md::RoleDescriptor *	role,
		const Application &	application,
		xmltooling::HTTPResponse &	httpResponse,
		const char *	defaultSigningProperty
	)		const

protected

Encodes and sends SAML 2.0 message, optionally signing it in the process.

If the method returns, the message MUST NOT be freed by the caller.

Parameters

encoder	the MessageEncoder to use
msg	the message to send
relayState	any RelayState to include with the message
destination	location to send message, if not a backchannel response
role	recipient of message, if known
application	the Application sending the message
httpResponse	channel for sending message
defaultSigningProperty	the effective value of the "signing" property if unset

Returns: the result of sending the message using the encoder

virtual long shibsp::AbstractHandler::sendPostResponse	(	const Application &	application,
		xmltooling::HTTPResponse &	response,
		const char *	url,
		DDF &	postData
	)		const

protectedvirtual

Post a redirect response with post data.

Parameters

application	the associated Application
response	outgoing HTTP response
url	action url for the form
postData	list of parameters to load into the form, as DDF string members
