Re: [undertow-dev] Force a HttpHandler to accept POST only

What do you want to happen if it is not a post request?
I was thinking about a 404 error, but indeed, 405 is more relevant.
The simplest way is just:
if(!exchange.getRequestMethod().equals(Methods.POST)) {
exchange.setResponseCode(405);
exchange.endExchange();
return;
}
This way suits me, thank you.
How can I retrieve the POST parameters ? I only can access the GET ones with
getQueryParameters().
For now you need to use io.undertow.server.handlers.form.FormDataParser (see
io.undertow.server.handlers.form.FormDataParserTestCase for an example).
I am not super happy with this API so it will probably change soon.
If you want to pick a handler to invoke based on the method you can use:
Handlers.predicate(Predicates.method(Methods.POST), postHandler,
nonPostHandler);
Do you think it’s a good idea to create a handler for any 404 error page and
use it here ?
If so, is it possible to set it as the default handler for all 404 errors ?
(I can do the check manually but I’m wondering if it is supported by
default)
io.undertow.server.handlers.ResponseCodeHandler#HANDLE_404
This is a handler that sets a 404 response code and ends.
If you want to generate a default error page for 404 responses have a look at
io.undertow.server.handlers.error.SimpleErrorPageHandler for an example of how to do this.
