How to add content to an empty message body

Hi,

We have developed a way for Rest calls sent using WebClient to be transparently sent either to a real backend or to our stubbing system. We have implemented this via an interceptor which intercepts the outgoing request and changes the url if certain headers (to indicate stubbing should be used) are present.

The stubbing system only supports POST at the moment and basically just matches the content of the POST body to determine the response to send back. So I am trying to work around this by converting a GET to a POST and placing the URL into the POST body as something to match against. Bizarre I know :-)

I have managed to change the HTTP request method ok, and can get access to the uri string but I just can't work out how to set the message content (which will be empty) to be the uri string.

This is what I have so far...

if (HttpMethod.GET.equalsIgnoreCase((String) message.get(Message.HTTP_REQUEST_METHOD))) {

// turn the GET into a POST
message.put(Message.HTTP_REQUEST_METHOD, HttpMethod.POST);

// and put the URL (minus the base path) into the POST body
String uri = (String) message.get(Message.REQUEST_URI);

OutputStream os = message.getContent(OutputStream.class);
CachedOutputStream cs = new CachedOutputStream();
try {
cs.write(uri.getBytes());

message.setContent(OutputStream.class, cs);
} catch (IOException ioe) {
ioe.printStackTrace();
}

Note my interceptor runs at SETUP phase and I am using CXF 2.7.12

Any help much appreciated!

Many thanks
Mandy
