requestEntityEmpty
Description
A filter that checks if the request entity is empty and only then passes processing to the inner route. Otherwise, the request is rejected.
See also requestEntityPresent for the opposite effect.
Example
final Route route = requestEntityEmpty(() ->
complete("request entity empty")
).orElse(requestEntityPresent(() ->
complete("request entity present")
));
// tests:
testRoute(route).run(HttpRequest.POST("/"))
.assertEntity("request entity empty");
testRoute(route).run(HttpRequest.POST("/").withEntity("foo"))
.assertEntity("request entity present");
