Remote Directory listingby johnfl68 (Beadle)
|on Jul 07, 2012 at 20:57 UTC||Need Help??|
johnfl68 has asked for the
wisdom of the Perl Monks concerning the following question:
I have been looking for examples to retrieve a list of image files from a remote directory (http - standard apache index) to load into an array so I can get the 10 most recent and copy them to my server (via getstore). There are typically only 20-40 images in this directory at any given time that are being rotated out. There are other things that I am doing after that with imagemagick, but I have that handled.
I have found a few examples, but they require robot or scraping modules, I am on a shared server and I am trying to do this with the modules that are installed. I am not really scraping, as I am only hitting the one remote server, and have permission to do so.
I am usually good at getting things to work if I have good examples to go by, but I've been searching for a week now and not having much luck. Worse case, the files follow a certain format, with a date and time in the file name (they are just not sequential). I could always do a loop starting from "now" and do a getstore for every possible name until I retrieve 10 existing files, but I would think there has to be some way to get a list of files in a remote directory without getting too carried away.
Thank you for the help!
