如何在Perl中链接文本？ [英] How do I linkify text in Perl?

问题描述

我有一些我希望链接的文本，我可以合理地使用正则表达式（搜索http / https或www），但我担心XSS并发症。在Perl中执行此操作的安全方法是什么？

I have some text I want to linkify, which I can reasonably do with a regex (search for http/https or www) but I'm worried about XSS complications. What's a safe way to do this in Perl?

推荐答案

XSS并发症的具体含义是什么？您是否只关注JavaScript或使用 http://example.com/形式的网址命令？type = delete; who = sam 等也关注你？

Exactly what do you mean by XSS complications? Are you only concerned with JavaScript or do URLs of the form http://example.com/command?type=delete;who=sam etc concern you as well?

至于链接URL，总会有边缘情况，但 Text :: Markdown 在各种输入上工作得很好。可以使用网址方法来预处理链接。

As for linkifying URLs, there will always be edge cases, but Text::Markdown worked pretty well on a variety of inputs when I tried it. You can use the urls method to preprocess the links.

请参阅也正则表达式::普通 。
