method :: forall h (ts :: [Type]). (Get h Method, ArrowChoice h, ArrowError RouteMismatch h) => StdMethod -> Middleware h ts (Method ': ts) Source #
Check whether the request has a specified HTTP method.
Example usage:
method @GET handler
If the request does not have the specified method, another handler will be tried.
It is also idiomatic to use the template haskell quasiquoter
match or route in
cases where both an HTTP method and a path need to be matched.
