Method Detail

getRelayState

@Nullable
 @NotEmpty
public static String getRelayState(@Nonnull
                                                        org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext)

Get the SAML protocol relay state from a message context.

Parameters:

messageContext - the message context on which to operate

Returns:

the relay state or null

setRelayState

public static void setRelayState(@Nonnull
                                 org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext,
                                 @Nullable
                                 String relayState)

Set the SAML protocol relay state on a message context.

Parameters:

messageContext - the message context on which to operate

relayState - the relay state to set

checkRelayState

public static boolean checkRelayState(@Nullable
                                      String relayState)

Checks that the relay state is 80 bytes or less if it is not null.

Parameters:

relayState - relay state to check

Returns:

true if the relay state is not empty and is less than 80 bytes

getEndpointURL

@Nonnull
public static URI getEndpointURL(@Nonnull
                                          org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext)
                                   throws BindingException

Get the response URL from the relying party endpoint. If the SAML message is a response and the relying party endpoint contains a response location then that location is returned otherwise the normal endpoint location is returned.

Parameters:

messageContext - current message context

Returns:

response URL from the relying party endpoint

Throws:

BindingException - throw if no relying party endpoint is available

setSAML1ResponseRecipient

public static void setSAML1ResponseRecipient(@Nonnull
                                             SAMLObject outboundMessage,
                                             @Nonnull @NotEmpty
                                             String endpointURL)

Sets the destination attribute on the outbound message if it is a ResponseAbstractType message.

Parameters:

outboundMessage - outbound SAML message

endpointURL - destination endpoint

setSAML2Destination

public static void setSAML2Destination(@Nonnull
                                       SAMLObject outboundMessage,
                                       @Nonnull @NotEmpty
                                       String endpointURL)

Sets the destination attribute on an outbound message if it is either a RequestAbstractType or a StatusResponseType message.

Parameters:

outboundMessage - outbound SAML message

endpointURL - destination endpoint

isMessageSigned

public static boolean isMessageSigned(@Nonnull
                                      org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext)

Determine whether the SAML message represented by the message context is digitally signed.

First the SAML protocol message is examined as to whether an XML signature is present. If not, then the presence of a binding signature is evaluated by looking at SAMLBindingContext.hasBindingSignature().

Parameters:

messageContext - current message context

Returns:

true if the message is considered to be digitally signed, false otherwise

isIntendedDestinationEndpointURIRequired

public static boolean isIntendedDestinationEndpointURIRequired(@Nonnull
                                                               org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext)

Determine whether the binding in use requires the presence within the message of information indicating the intended message destination endpoint URI.

Parameters:

messageContext - current SAML message context

Returns:

true if the intended message destination endpoint is required, false if not

getIntendedDestinationEndpointURI

@Nullable
public static String getIntendedDestinationEndpointURI(@Nonnull
                                                                 org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext)

Extract the message information which indicates to what receiver endpoint URI the SAML message was intended to be delivered.

Parameters:

messageContext - the SAML message context being processed

Returns:

the value of the intended destination endpoint URI, or null if not present or empty

Throws:

org.opensaml.messaging.MessageException - thrown if the message is not an instance of SAML message that could be processed by the decoder

getActualReceiverEndpointURI

@Nonnull
public static String getActualReceiverEndpointURI(@Nonnull
                                                           org.opensaml.messaging.context.MessageContext<SAMLObject> messageContext,

Extract the transport endpoint URI at which this message was received.

Parameters:

messageContext - current message context

request - the HttpServletRequest being evaluated

Returns:

string representing the transport endpoint URI at which the current message was received

Throws:

org.opensaml.messaging.MessageException - thrown if the endpoint can not be looked up from the message context and converted to a string representation
