Re^2: CGI Input with Escaped Characters

That looks correct, and may work, but I try to keep the Perl code so that it'll work from command line too for troubleshooting. When I output the $ENV{} from command line, it doesn't show to that as an available key. Would that only work from a web posting action? Thanks!

You can pass CGI parameters on the command, using `data=foo api_key=1234`. See the DEBUGGING section of CGI. But I doubt that CGI will shoehorn that back into `%ENV`. You could set the environment variable on the command line also `$ env QUERY_STRING=data=foo&api_key=laurel%26hardy script.cgi` [download] or you could check inside your script if it is run from the commandline: `if (-t STDIN) { # command line. for params, substitute special chars (e.g. & => %2 +6) # (there must be a module out there which does that for you) } else { # via webserver }` [download] perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]
