URL Escaping

on Dec 28, 2000 at 03:25 UTC ( #48552=perlquestion: print w/replies, xml ) Need Help??

electronicMacks has asked for the wisdom of the Perl Monks concerning the following question:

Fellow monks:

Iím writing a script that (among other things) converts strings to URL encoded format. Iíve been using uri_escape from URI::Escape which works great for some characters (like spaces) but does not, by default, escape characters such as & and ; although it is possile to turn on each of these characters individualy, I can't shake the feeling that there must be a better way...

So, my question is, can anyone recommend a good module that will encode all non alphanumeric characters? How about all but : and /

A humble monk,
electronicMacks

    The function uri_escape takes an optional second argument that's a list of all characters that you want to encode. The following should work for you:
    #!/usr/bin/perl -w use strict; use URI::Escape; my $cgi_chars = '\x00-\x29\x2b\x2c\x2f\x3a-\x40\x5b-\x5e\x60\x7b-\xff +'; my $bad_chars = '^%$&='; print uri_escape( $bad_chars, $cgi_chars );

    Cheers,
    Ovid

    How about CGI::escape()? It translates everything except [a-zA-Z0-9_.-]. If it doesn't do what you want, you can always grab the four or five line definition out of CGI.pm and customize it for your needs.

    It's not supposed to escape those because those are legal characters in a URL. (Didn't we do this one already?)

    There's nothing wrong with a URL of

    http://www.stonehenge.comm/cgi/foobar/fred&barney
    That doesn't mean that fred or barney are query parameters. The ampersand is only of some significance after the question mark.

    If you want to build a query string from pieces, use the proper part of URI... the parts with the word query in them.

    Stop trying to use the wrong tool for the wrong job in the wrong way.
