Response<T> is an optional wrapper
for the return type of route handlers. Use it when you want to control additional parameters of the
service reply like setting a different status code or adding headers.
Examples:
Response<String> handle(RequestContext requestContext) {
String s = stringResponse();
return Response.forPayload(s)
.withHeader("X-Payload-Length", String.valueOf(s.length()));
}Response<String> handle(RequestContext requestContext) {
String arg = requestContext.request().getParameter("arg");
if (arg == null || arg.isEmpty()) {
return Response.forStatus(
Status.BAD_REQUEST.withReasonPhrase("Mandatory query parameter 'arg' is missing"));
}
return Response.forPayload("Your " + arg + " is valid");
}
