processing POST help - direction needed
Hi Folks,
I am stuck at how to handle post of a file. For example i want to upload a file, do some processing like check for virus (during POST), then hand it back to normal POST operation.
Is it possible to achieve this using POST.esp and how?
Your input will be greatly appreciated.
Regards
Jithesh

Not that I'm aware of.
One thing I noticed, with the example I gave you, there are some limits with
request.getParameter() [1] (Servlet API) so you may want to use
slingRequest.getRequestParameter() [2] (Sling API) instead. That will give
you .getSize() and .getInputStream().

A quick follow up question, i was browsing documentation and i think there is
no configurable parameter at present to set the max file size that can be
uploaded. I hope i am right, unless i missed something. If such a thing was
there that could have helped me as well :)

The 3rd example of a POST.jsp gets you 90% of the way there, but I don't see
how you're going to completely avoid java.
How do you plan on performing this virus scan?
Assuming you have some java based virus scan api, you can take the POST.jsp
they give you and replace this line:
contentNode.setProperty("jcr:data", new
ByteArrayInputStream(request.getParameter("myfile").getBytes()));
with something like:
byte[] bytes = request.getParameter("myfile").getBytes();
if(bytes.length > 1024*1024*2 ) {
//larger than 2MB so throw exception or something
}
if(AntivirusUtility.isDirty(bytes)){
//infected so throw exception
}
contentNode.setProperty("jcr:data", new ByteArrayInputStream(bytes));
...

Thank you very much for the quick response Mark. I did have a look at that
link, but did not get an answer to what i was looking for. Let me elaborate.
Let me put it in simple terms (without getting into my need complexity :)),
What i need is
I have an HTML form to upload files.
I can hand it over to sling to do the post after file is selected,
but before that i want to check if the file has virus,
or is within the permitted file size & type (this i can do with javascript,
but if there is a user who uses curl to upload, need to trap that)
After i trap and validate the file is fine for upload, i need to hand it over
to sling to finish the POST operation
I hope this gives an idea of the scenario. I am not a JAVA person, so trying
to see if i can accomplish this with something like POST.esp :).

Not sure about "hand it back to normal POST operation" but this[1] may get
you what you need.

Hi Folks,
I am stuck at how to handle post of a file. For example i want to upload a
file, do some processing like check for virus (during POST), then hand it
back to normal POST operation.
Is it possible to achieve this using POST.esp and how?
Your input will be greatly appreciated.

Hmm since i am not a Java person and pretty new into programming, want to see if i can circumvent my issue using .esp.

How about using a filter for this extra processing?
Alternatively, you could use a PostProcessor. At that point, the file
node/properties have been created in the Session, but the Session has
not been saved, so you can abort at that point.
