It's the silly season, so here goes...
Unlike more or less everyone else on this list (I suspect) I am not
used to mixing Rev and the Internet. I've been looking at the RunRev
tutorial material about this sort of thing, and some of it I
understand pretty easily - for example the stack for retrieving
weather data from the BBC web site. This essentially calculates image
names on the basis of a convention used by the BBC for the time,
region or whatever and then downloads them. Fine. Now what about the
kind of site that invites you to put in some reference (say it's a
catalogue reference or a post code or some key or other), after which
you activate some kind of server-side code execution by clicking a
button, pressing return or whatever; this then generates a result,
let's say an image of a particular product in the catalogue, which is
visible via the user's browser; this resultant image is not available
via a URL until explicitly retrieved or constructed for the user's
benefit, for example it might be extracted from a database, so the BBC
Weather example doesn't apply.
Now, what if I want to use a Rev program to simulate the user
interaction to a site like that - so that my Rev program inserts the
product code, presses return, waits for the image to be generated, and
then downloads it (not a screen grab, since the image might have a
higher resolution than the browser can display)? What I need is a way
of interacting with the web page(s) involved (or really the underlying
html), almost by simulating key strokes. I suppose I want to treat the
html as a kind of API for the facilities of the site.
Is this possible, and is it possible without using an external
browser? I feel it ought to be, but I just don't know where to start.
Can anyone explain what kind of route I should follow?
TIA
Graham
