I am trying to script the downloading of European patents from the
European Patent Office's server. They provide a sample URL to use
for that purpose, but instead of the patent, I instantly get a zero
size file. I've tried it with and without URLencode. However,
scriptiing with revGoURL works fine with the same URL to open the
patent in my browser. Any ideas? The script I am using goes like
this:
on mouseup
put
"https://publications.european-patent-office.org/PublicationServer/getpdf.jsp?cc=EP&pn=1502503&ki=A1";
into theURL
put URL theURL into URL "binfile:1502503.pdf"
end mouseup
Could it be that Rev is allergic to JavaServer Pages? I hope not.
Thanks for any help that you might be able to give.

This is a plea, not just to Bruce, but to all of you who do things
like this, most of whom should know better.
When you deal with URLs, especially internet URLs, things sometimes
go wrong. Often these things are outside of your control, such as
the network being busy, being given the wrong URL by your boss, your
ISP's data center being struck by an asteroid, or a dud hard drive.
It's important that you check that things happen as expected. So
every time you make a url request, always (i.e. always) check "the
result".
In the example above, there are two url requests in the same line.
So should you check the result twice? I'd say "yes". Something like
this:
put URL theURL into theData
put the result into theRes
if theRes <> empty then
answer theRes ## or whatever you need to do
else
put theData into URL "binfile:1502503.pdf"
put the result into theRes
if theRes is not empty then
answer theRes ## or whatever you need to do
else
##carry on
end if
end if

Apart from that, I think Ken's pointer to
"libURLSetSSLVerification" will probably work. This will mean that
you won't be able to authenticate the remote server. Perhaps OK for
the patent office, but probably not a good idea for doing bank
transactions. The alternative is to set the sslCertificates property
to an appropriate certificates file.

Thanks, Dave, for the mauling. It was well deserved. However, I have
been trying to get this to work over a period of several weeks. This
was not a "try once and cry for help." This has been a long, drawn
out bit of frustration. A couple of times I did throw "the result"
into the script, but it was very un-enlightening. I also alternated
using "revGoURL" with the same URL, and bingo, the patent showed up
in Netscape. So there were no issues with the EPO server at the
times I was trying.
With that introduction, the "Result #1" (see below) shows the single
word "error". Not very enlightening! I am using the following
handler, if anyone wishes to try it:
on mouseUp
libUrlSetSSLVerification false
put
"https://publications.european-patent-office.org/PublicationServer/getpdf.jsp?cc=EP&pn=1502502&ki=A1";
into theURL
put URL theURL into holdData
put the result into theRes
if theRes <> empty then
answer "Result #1: " & theRes
else
put holdData into URL "binfile:1502503.pdf"
put the result into theRes2
if theRes2 <> empty then
answer "Result #2: " & theRes2
end if
end if
end mouseUp
Again, if you substitute "revgourl theURL" in the appropriate place,
you will have the patent showing up in your browser in no time
(figuratively speaking, of course). Any hints for this problem would
be appreciated!
Regards,
Bruce Pokras
