Path parameters can't be empty.

[Timmmm]

If you have a parameter with type path that you leave blank, swagger-ui won't let you submit the request even if the parameter is optional.

For example I have a URI like this: http://foo.com/search/{query} and I might want search for everything using a blank query like this: http://foo.com/search/ but currently swagger won't let me submit that request (clicking the "Try it out!" button does nothing).

with swagger, path params are always required, or it changes the overall route syntax. I think that would be quite difficult to change

[Timmmm]

I don't follow, isn't it just a textual search & replace?

You can certainly hack around in the swagger-ui, but in general, swagger wants path parameters to be required. For instance:

/foo/{bar}/search
/foo/search

If {bar} is omitted, the container would receive /foo//search which is interpreted as /foo/search in many server frameworks. To avoid the pitfalls of that, swagger says path parameters are required.

Hi, this is a duplicate of #380

Closing this one as there's more information in #380.
