问题描述

我在PERL中工作，并且我有一个html结果页，可以完美显示。我想添加一个按钮，使此html页面成为可下载到您计算机上的pdf。以下是生成html页面的代码。在CGI代码中生成了fileFH。

I am working in PERL and I have an html results page that displays perfectly. I want to add a button that makes this html page a pdf that downloads onto your machine. Below is the code that generates the html page. fileFH is generated in the CGI code.

sub searchResults {
my $data = shift;
my $file = "$OUTFILES/$data.html";

open(my $fileFH, '<', $file) or return "Can not find file\n";

print $cgi->header();

while (<$fileFH>) {
    print qq($_);
}
close($fileFH);
}

推荐答案

如果您愿意接受外部程序/转换的依赖性我强烈建议 http://wkhtmltopdf.org/

If you are open to an external program/dependency for the conversion I highly recommend http://wkhtmltopdf.org/

流量：

1. 按钮单击


2. wkhtmltopdf提供了目标URL


3. 发送给用户的输出

您可能还希望缓存输出以减少数量

You may want to cache the output as well to reduce the number of conversions.

编辑
Perl也已经具有包装器。

EDIT Perl already has a wrapper too.
