Swagger: support for optional routes

问题

I have a route with an optional parameter:

    [Route("{categoryId?}")]
    public HttpResponseMessage Get(int? categoryId=null)

However, when I don't provide a value for categoryId the call includes {categoryId?} in the request itself...

http://myhost/api/%7BcategoryId%7D

Swagger has no support for optional path parameters. If you wish to document it this way, you'd have to create two separate paths - one without the path parameter and one with.
