blocks|key|5024275|text|最简单的选择是配置您的web服务器以支持CGI，然后编写遵循CGI协议的Perl+(+CGI+module对此很有帮助)。如果愿意，您可以将服务器配置为执行任何扩展名为.pl的文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5024276|更复杂，但更灵活的是PSGI/Plack。这是一组中间件，您可以通过各种方式(例如FastCGI或mod_perl)连接到web服务器以获得更好的性能。这也提供了一些很好的调试选项。有一个你可能会发现有用的advent+calendar+style+guide。|5024277|entityMap|0|LINK|mutability|MUTABLE|url|https://metacpan.org/module/CGI|1|http://plackperl.org/|2|http://advent.plackperl.org/2009/12/day-1-getting-plack.html^0|17|A|0|0|A|A|1|2V|R|2|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]|$A|Z|B|10|1|11]]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

The simplest option is to configure your web server to support CGI and then write your Perl to follow the CGI protocol (the <a href="https://metacpan.org/module/CGI" rel="nofollow">CGI module</a> is helpful for this). You can configure servers to execute any file with a .pl extension if you wish.

Slightly more complicated, but more flexible, is <a href="http://plackperl.org/" rel="nofollow">PSGI/Plack</a>. This is a set of middleware that you can hook up to a web server in a variety of ways (e.g. FastCGI or mod_perl) for better performance. This also gives some nice debugging options. There is an <a href="http://advent.plackperl.org/2009/12/day-1-getting-plack.html" rel="nofollow">advent calendar style guide</a> that you might find useful.

blocks|key|5024286|text|从幼稚的角度来看，您的web服务器似乎没有正确配置；它应该解释文件，而不是分发文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5024287|出于好奇心，既然你懂PHP，为什么还要用Perl做web东西呢？我想我不久前读过一篇文章，说PHP在显示网页时比Perl更快。|5024288|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

From a naive approach, it sounds like your web server isn't configured properly; it should be interpreting the file, not handing it out.

Out of curiosity, why are you using Perl for web stuff if you know PHP? I thought I read an article a while back stating that PHP was faster than Perl when used for displaying webpages.

print+"</html>";|code-block|syntax|javascript|5024344|然后看看“CGI”，"REQUEST_METHOD“和"QUERY_STRING”这样的变量，你就可以知道CGI模块在后台做了什么。|5024345|重要的是要知道您的脚本必须位于为运行cgi脚本而设置的目录中，如下所示：|5024346|ScriptAlias+/cgi_bin/+/var/cgi_bin/+++++++++++++++++++++++++++++++++++++++++++++

If you want to start with Perl5 web development it is usefull to start with CGI, but that
is not necesity.

There is <a href="http://perldoc.perl.org/CGI.html" rel="nofollow">CGI</a> module. You could look at how HTTP works
and how Apache or whatever server you use calls your CGI program. Good start is using this
script:

<pre><code>#!/usr/bin/env perl 

use strict; 
use warnings; 

print "Content-type: text/html\n\n"; 
print "&lt;html&gt;"; 
print "&lt;body&gt;"; 
print "&lt;table&gt;"; 
for my $var_name (keys %ENV) { 
 print "&lt;tr&gt;"; 
 print "&lt;td&gt;$var_name&lt;/td&gt;"; 
 print "&lt;td&gt;$ENV{$var_name}&lt;/td&gt;", "\n"; 
 print "&lt;/tr&gt;" 
} 
print "&lt;/table&gt;"; 
print "&lt;/body&gt;"; 
print "&lt;/html&gt;";
</code></pre>

Then looking at variables like "REQUEST_URI", "REQUEST_METHOD" and "QUERY_STRING", you can
get idea what CGI module is doing in background.

It's important to know that your script must be at directory that is set up to run cgi
scripts, like:

<pre><code>ScriptAlias /cgi_bin/ /var/cgi_bin/ 

&lt;Directory /var/cgi_bin/&gt; 
 Options +ExecCGI 
 AddHandler cgi-script .cgi .pl 
&lt;/Directory&gt;
</code></pre>

And file have to be executable by any user that runs your server (eg. Apache2), and readable.

Also after this you can look at modern toolkits like <a href="http://www.catalystframework.org/" rel="nofollow">Catalyst</a> &amp; <a href="http://mojolicious.org/" rel="nofollow">Mojolicious</a>. I recomend
you mojolicious. Also there is web framework called <a href="http://perldancer.org/" rel="nofollow">Dancer</a>.

About frameworks, Catalyst is long time here and it works, but it kind of took some kraft with it. This is tried to be fixed with new frameworks like mojolicious. Mojolicious don't
have almost no external CPAN dependencies.

blocks|key|5024390|text|XoR已经提到过了，但我想重申：Mojolicious！它有一个模板引擎，允许您在HTML中混合使用Perl代码，但是您可以在应用程序内部完成大部分繁重的工作。Mojolicious还包括(几个)内置web服务器(一个用于测试，一个用于生产)，这些服务器比Apache更容易使用。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5024391|易于安装:只需使用cpan+(或其他)安装Mojolicious即可。|style|CODE|5024392|写一个基本的脚本：(一个简单的Hello+World+)：|5024393|#!/usr/bin/env+perl

XoR has already mentioned it, but I want to reiterate: <a href="http://mojolicio.us" rel="nofollow">Mojolicious</a>! It has a templating engine that lets you intermix Perl code in the HTML, however you can do most of the heavy lifting inside the application itself. Mojolicious also includes (several) built-in web servers (one for testing, one for production), which are far easier to use than Apache.

Easy to install: just install <code>Mojolicious</code> using <code>cpan</code> (or other).

Write a basic script: ( a simple Hello World ):

<pre><code>#!/usr/bin/env perl

use strict;
use warnings;

use Mojolicious::Lite;

get '/(:name)' =&gt; {name =&gt; 'World'} =&gt; sub {
 my $self = shift;
 $self-&gt;render('index');
};

app-&gt;start;

&lt;body&gt;
 Hello &lt;%= $name %&gt;
&lt;/body&gt;
&lt;/html&gt;

And run: <code>morbo myapp.pl</code>

I'm new to Perl programming. How can I use it instead of PHP? In Xampp or PHP we have "htdocs" to store our .php files but how could I save my .pl file? 

When I try to open a .pl through localhost the whole file was downloadable, unlike in php when we open a .php, the php code is executed.

How can I write server side code in Perl for the WWW?

我是Perl编程的新手。我怎样才能用它代替PHP？在Xampp或PHP中，我们有"htdocs“来存储我们的.php文件，但是我如何保存我的.pl文件呢？当我试图通过本地主机打开一个.pl时，整个文件都是可以下载的，不像在php中我们打开一个.php时，php代码是被执行的。
