constrain

public static Action constrain(Collection<? extends String> methods)

Constrains a request to the given set of methods. Always includes OPTIONS. GET implies HEAD.

When OPTIONS is not in the given set of methods, responds to the request if is the OPTIONS method and stops rules processing. OPTIONS requests are passed-on when included in the set of methods. See https://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.2

Responds with 405 Method Not Allowed if the request is not one of the given methods, OPTIONS, or an implied HEAD. See https://datatracker.ietf.org/doc/html/rfc7231#section-6.5.5.

No action is taken when the dispatcher is DispatcherType.INCLUDE, due to the servlet specification making the setting of status codes and headers impossible within includes. See RequestDispatcher.include(javax.servlet.ServletRequest, javax.servlet.ServletResponse) for more details.

TODO: Wrap request/response to convert HEAD to GET here when HEAD implied? Redundant with servlet and Spring MVC behavior, but would not hurt and assumes less about the underlying resources?

TODO: Should this only be applied on the DispatcherType.REQUEST dispatcher instead of just skipping DispatcherType.REQUEST? Should this throw an exception instead of silently taking no action on skipped dispatchers?

Returns:

Action.Result.TERMINATE if has responded to OPTIONS or with 405 status. Action.Result.CONTINUE if the request method is one of the given methods.
