Member Function Documentation

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

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

std::pair<bool,bool> shibsp::AbstractHandler::getBool	(	const char *	name,
		const SPRequest &	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

Returns:

a pair consisting of a nullptr indicator and the property value iff the indicator is true

std::pair<bool,int> shibsp::AbstractHandler::getInt	(	const char *	name,
		const SPRequest &	request,
		unsigned int	type = HANDLER_PROPERTY_ALL
	)			const [protected]

Returns an integer-valued property.

Parameters:

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

Returns:

a pair consisting of a nullptr indicator and the property value iff the indicator is true

std::pair<bool,const char*> shibsp::AbstractHandler::getString	(	const char *	name,
		const SPRequest &	request,
		unsigned int	type = HANDLER_PROPERTY_ALL
	)			const [protected]

Returns a string-valued property.

Parameters:

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

Returns:

a pair consisting of a nullptr indicator and the property value iff the indicator is true

std::pair<bool,unsigned int> shibsp::AbstractHandler::getUnsignedInt	(	const char *	name,
		const SPRequest &	request,
		unsigned int	type = HANDLER_PROPERTY_ALL
	)			const [protected]

Returns an unsigned integer-valued property.

Parameters:

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

Returns:

a pair consisting of a nullptr indicator and the property value iff the indicator is true

void shibsp::AbstractHandler::log	(	SPRequest::SPLogLevel	level,
		const std::string &	msg
	)			const [protected, virtual]

Log using handler's specific logging object.

Parameters:

	level	logging level
	msg	message to log

Reimplemented from shibsp::Handler.

virtual void shibsp::AbstractHandler::preservePostData	(	const Application &	application,
		const xmltooling::HTTPRequest &	request,
		xmltooling::HTTPResponse &	response,
		const char *	relayState
	)			const [protected, virtual]

Implements a mechanism to preserve form post data.

Parameters:

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

virtual DDF shibsp::AbstractHandler::recoverPostData	(	const Application &	application,
		const xmltooling::HTTPRequest &	request,
		xmltooling::HTTPResponse &	response,
		const char *	relayState
	)			const [protected, virtual]

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,
		bool	signIfPossible = false
	)			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
	signIfPossible	true iff signing should be attempted regardless of "signing" property

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 [protected, virtual]

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
