Bug #75120 for CGI: '+' converted to space in POST/GET

Subject:

'+' converted to space in POST/GET

For a simple program like this (named cgi.pl): #!/usr/bin/perl -w use strict; use CGI; my $cgi = new CGI; print $cgi->param('a'); All plus characters are converted to spaces: ./cgi.pl 'a=1+2' 1 2 Same happens if I try it with a POST or GET request. The 9 year old bug returned: https://rt.cpan.org/Public/Bug/Display.html?id=1933 (perl v5.12.4 built for i486-linux-gnu-thread-multi-64int) Tried in CGI v3.43 and v3.49

This is spec-compliant. You'll find that even more modern tools do this: # Also translates plus to space use Plack::Request; my $r = Plack::Request->new({ QUERY_STRING => 'a=1+2' }); print $r->param('a'); There was a discussion about this in the PHP bug tracker: https://bugs.php.net/bug.php?id=39078&edit=1 You'll see that ultimately points back to a spec: http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1 On these docs on About.com, you'll also laid out in a table that "Plus indicates a space": http://webdesign.about.com/od/forms/a/url_encoding.htm You used a reserved character improperly and should encode it to achieve your expected result.
