Perl CGI 元标签

Question

根据 http://perldoc.perl.org/CGI.html制作meta标签，举例如下:

print start_html(-head=>meta({-http_equiv => 'Content-Type',-content => 'text/html'}))

但是使用下面的代码:

#!/usr/bin/perl
use strict;
use warnings;
use CGI;

my $cgi = new CGI;
$cgi->autoEscape(undef);
$cgi->html({-head=>meta({-http_equiv => 'Content-Type',-content => 'text/html',-charset=>'utf-8'}),-title=>'Test'},$cgi->p('test'));

我收到以下错误:

$ perl test.cgi Undefined subroutine &main::meta called at test.cgi line 8.

我正在尝试生成以下标签:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

meta sub 在您使用 CGI; 时不会自动导入。试试看

use CGI "meta";

(或 ":all")。
