Always passes the request on to its inner route (i.e. does nothing with the request or the response).

Consumes a leading slash and extracts the next path segment, unmarshalling it and passing the result to the inner function, expecting the full path to have been consumed then.

Applies the given PathMatcher0 to the remaining unmatched path after consuming a leading slash. The matcher has to match the remaining path completely. If matched the value extracted by the PathMatcher0 is extracted on the directive level.

Rejects the request if the unmatchedPath of the akka.http.javadsl.server.RequestContext is non-empty, or said differently: only passes on the request to its inner route if the request path has been matched completely.

Only passes on the request to its inner route if the request path has been matched completely or only consists of exactly one remaining slash.

Note that trailing slash and non-trailing slash URLs are not the same, although they often serve the same content. It is recommended to serve only one URL version and make the other redirect to it using #redirectToTrailingSlashIfMissing or #redirectToNoTrailingSlashIfPresent directive.

For example:

def route = {
  // redirect '/users/' to '/users', '/users/:userId/' to '/users/:userId'
  redirectToNoTrailingSlashIfPresent(Found) {
    pathPrefix("users") {
      concat(
        pathEnd {
          // user list ...
        },
        path(UUID) { userId =>
          // user profile ...
        }
      )
    }
  }
}
