Paths ending with an extension aren't matched

[dunglas]

When using the router, the following definition is matched properly (the corresponding route is found):

paths:
  '/books/{id}':
    parameters:
      - schema:
          type: integer
        name: id
        in: path
        required: true
    get:
      # ...

But this doesn't:

paths:
    parameters:
      - schema:
          type: integer
        name: id
        in: path
        required: true
  '/books/{id}.json':
    get:
      # ...

Looks like the path (.json) like got carried around by mistake?
Looking at

kin-openapi/openapi3/server.go

Lines 23 to 35 in 41b6ab9

	func (servers Servers) MatchURL(parsedURL *url.URL) (*Server, []string, string) {
	rawURL := parsedURL.String()
	if i := strings.IndexByte(rawURL, '?'); i >= 0 {
	rawURL = rawURL[:i]
	}
	for _, server := range servers {
	pathParams, remaining, ok := server.MatchRawURL(rawURL)
	if ok {
	return server, pathParams, remaining
	}
	}
	return nil, nil, ""
	}

I don't see what the issue would be.
Can you present a valid spec maybe along with the code you're using?
