5:32 p.m.
I can't figure out how to get the content of post data
My server start
Undertow.builder()
.addHttpListener(8080, "0.0.0.0")
.setHandler(Handlers.routing().post("/bid", new BidHandler()))
.build()
.start();
And the handler class
public final class BidHandler implements HttpHandler {
@Override
public void handleRequest(final HttpServerExchange exchange) throws
Exception {
........
}
}
If I make a curl request like so
curl -H "Content-Type: application/json" -X POST -i -d '{"some":
"value"}'
http://127.0.0.1:8080/bid
It gets to the handler, but I can't figure out to access the post data from
the request
Thanks

If you just want access to the raw data you have a 2 options:
HttpServerExchange.getRequestChannel()
HttpServerExchange.getInputStream() (exchange should have startBlocking called, and you
need to dispatch to a worker thread so as not to block an IO thread)
If you want access to parsed form/multipart data then you can use
io.undertow.server.handlers.form.EagerFormParsingHandler, and the use
exchange.gutAttachment(FormDataParser.FORM_DATA) to get access to the parsed data.

Thanks, I ended up figuring out how to do the second method you listed. Is
there any advantage to one verse the other?

By second method do you mean the input stream or the parsers?
If you just want form data just use the built in parsers, if you need access to the raw
bytes then you need the input stream or the channel. The channel lets you use non-blocking
IO which can perform better, however it is a bit harder to use that the input stream as
you need to register callbacks.

I ended up dispatching to a worker thread and using input stream. I do need
access to the raw post data. Do you have an example of how to use channel
so I could try it for comparison sake?

io.undertow.util.StringReadChannelListener is probably the simples example.
Basically the idea is you keep calling read() until it returns 0 (or -1
if the stream is done), then when it returns 0 you call
channel.getReadSetter().set(myReadListener)
channel.resumeReads()
your listener will be notified when more data is available and you can
attempt to read again.
We have been talking about adding some kind of simpler async reader API,
however we are not sure yet exactly what form this will take.
