You can use the Receiver API, specifically for that purpose.
On the exchange, call: getRequestReceiver();
You will get a receiver object:
https://github.com/undertow-io/undertow/blob/master/core/src/main/java/io...
On the receiver you can call: receiveFullString, you have to pass it a
callback that will be called when the whole body has been read.
Please share your results when you test this further!
Cheers,
Antoine

reading request body in undertow ?
