Possible to POST using a HTML Generator?
Hi guys,
I wonder if anyone could help me: (pretty please? ;))
I'm trying to get hold of the results of a POST request made to a remote
server - does anyone know if this is possible using the HTML generator? The
reason I need to use this generator (I think) is that the results of the
request will probably be HTML rather than XML, and I get the impression that
this is the only generator that will handle regular HTML (using JTidy)?
After substantial wanderings through the cocoon folklore, I hear that the
Web Service Proxy Generator might do want I need, except that: 1) it
requires well formed XML to come back which I don't have, and 2) it requires
cocoon version 1.2 at least, and I'm unfortunatly not in a position to
upgrade yet.
What I'd ideally like to do is pass on any post parameters that cocoon gets,
and forward them to the remote server before formatting the results of the
post and passing them back to the user.
Could anyone give me any hint at all as to what direction I should research
in? Is this even =possible= using cocoon?
Any ideas at all would be very gratefully recieved!
Thanks,
Nick

Correcting myself: of course it can be done. It can't be done by
configuring the current set of components available. A new component,
or additional capability added to an existing component is needed.

Argh. Now it's my turn to miss the details! Yes, I was combining these
in my pea brain. I don't know how the Source handles the http:// -
maybe that's the place to deal with the post.
Sounds like bottom line is - it can't be done at present. (unless he
doesn't really need POST but can substitute GET).

Then I did not remember correctly (or it has changed in the meantime). I
thought there was a "we do not handle GET exception" anywhere.

The WSProxy and the HttpProxy both use commons-httpclient, but I believe
that "down below", the HTMLGenerator seems to use a Source. I'm not
sure how this is handled under the hood of source though, it could just
be java.net.URL, or something.

This is wrong -- they can use either GET or POST, configured via parameter.

Oh no, I missed "results of a POST request". I combined POST and HTML
and XML and thought file upload. Sorry for that.

HTMLGenerator? Why it should use httpclient? The proxy generators, yes.
We have an example accessing remote server with HTMLGenerator in the
Cocoon samples (the page switched from Yahoo News to Google SciFi not so
long ago).
<map:generate type="html" src="http://www.remoteserver.com"/>
But this will not result in a POST AFAIK, but a GET request, while the
proxy generators only handle POST.

The WebServiceProxyGenerator and the HttpProxyGenerator both are
configurable for POST, but they require XML back from the remote
service. Perhaps we should think about refactoring a proxy so it
requires XML or not (ran through tidy). There's definately some
similarity between these components.

I don't see anything related to file uploads below. I thought he just
wanted to proxy a normal form post. Am I missing it?
As the HTML generator uses the httpclient package I think it could be
modified to do this, but I don't know for sure.

Should be possible if an action handles the file upload, stores the file
on the server, returns the position on the server to the sitemap. The
HTMLGenerator (yes it's the only possibility of pushing HTML through the
pipeline) reads it from there and the rest goes on as normally.
Is this correct, Mr. File Upload Geoff? ;-)
