使用Perl代码
#!/usr/bin/perl
use strict;
use warnings;
use CGI ":all";
use Encode;
my $cgi = new CGI;
$cgi->charset('utf-8');
print $cgi->header(-type => 'text/html',
-charset => 'utf-8');
print $cgi->start_html(-title => 'Test',
-head => meta({-http_equiv => 'Content-Type',
-content => 'text/html; charset=utf-8'}));
my $text = 'test'; # for now
Encode::from_to($text, 'latin1', 'utf8');
print $cgi->p($text);
print $cgi->end_html;
我得到以下输出:
Content-Type: text/html; charset=utf-8
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US">
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head>
<body>
<p>test</p>
</body>
我不知道为什么
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
在输出中,我不知道如何摆脱它。
我们将不胜感激。

使用最新版本的CGI.pm(我目前安装了3.52),您不需要手动构建<meta>
元素。您只需在调用header
方法时提供字符集。这个计划:
#!/usr/bin/perl
use strict;
use warnings;
use CGI ":all";
use Encode;
my $cgi = CGI->new;
binmode STDOUT, ':utf8';
print $cgi->header(-type => 'text/html',
-charset => 'utf-8');
print $cgi->start_html(-title => 'Test');
my $text = "\x{201c}test\x{201d}"; # for now
print $cgi->p($text);
print $cgi->end_html;
给了我这个输出:
Content-Type: text/html; charset=utf-8
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US">
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<p> test </p>
</body>
</html>

向-encoding
添加start_html
参数,不要手动构建元素。 (尽管CGI文档建议你做什么)。
print $cgi->start_html(-title => "Test", -encoding => "utf-8")
