Yup, you can't, this is how webapps work in general, sorry. But you can
create a filter to get what you want, read on.
The problem is that if it's a POST request, someone (webapp container,
request object) has already digested the whole body of the request and
convert it into properties of the form. So someone else has already
gone through and gobbled up all of the data (simple unbuffered stream),
so you can't get a look at it. This is the most efficient way, and most
people don't complain.
That's exactly how I understand the thing. And you also exactly
understand my needs! :-) Thanks.
Now, the only way to do what you're trying to achieve is to essentially
copy the data before it's taken away. If I remember correctly the
process of converting the body into properties is kicked off on the
first getProperty command. So you have to create a Filter that replaces
the request object, with one that buffers or copies the request body,
while still making it available through normal api calls. Then I would
probably put that byte[] into a request attribute (
request.setAttribute, or override request.getAttribute ), and that's how
you would get access to it.
Very well understand that. But no idea where to begin...
Is that filter a Tapestry Service thing? Or a Tomcat thing?
byte[] body = (byte[]) ...getRequest().getAttribute( "rawbody" );
cool? que sera, sera.
Yes, very!
So you have to create a request object that on construction absorbs the
body into a byte[], re-exposing it through a ByteArrayInputStream, and
putting it into a request.Attribute. Again, this won't be the most
efficient way of doing things, so just map the filter against the urls
that actually need the support. :)
OK, nice. That's exactly what I need. But if you could provide some more
help on how to do it, where to begin, which object to create, where to
put it, ...
Thanks a lot.
