pathSuffix

Description

Matches and consumes a suffix of the unmatched path of the RequestContext against the given PathMatcher, potentially extracts one or more values (depending on the type of the argument).

This directive filters incoming requests based on the part of their URI that hasn't been matched yet by other potentially existing path matching directives on higher levels of the routing structure. Its one parameter is usually an expression evaluating to a PathMatcher instance (see also: The PathMatcher DSL).

As opposed to pathPrefix this directive matches and consumes the unmatched path from the right, i.e. the end.

Depending on the type of its PathMatcher argument the pathPrefix directive extracts zero or more values from the URI. If the match fails the request is rejected with an empty rejection set.

Example

final Route route = 
    route(
        pathPrefix("start", () -> 
            route(
                pathSuffix("end", () -> completeWithUnmatchedPath.get()),
                pathSuffix(segment("foo").slash("bar").concat("baz"), () -> 
                    completeWithUnmatchedPath.get())
            )
        )
    );
// tests:
testRoute(route).run(HttpRequest.GET("/start/middle/end")).assertEntity("/middle/");
testRoute(route).run(HttpRequest.GET("/start/something/barbaz/foo")).assertEntity("/something/");
