Specs

known_method?(Plug.Conn.t()) :: true | false

Check of the HTTP method in the request is one we know about.

This is different from allowed_methods/1 in that this function checks to see if the given HTTP method is an HTTP method at all. You probably want to override allowed_methods/1 and not this one, unless you're extending HTTP with more verbs.

If this function returns false, then the plug will return a 501 Unknown Method response.

By default, allows the methods returned by known_methods/1.
