问题描述

我希望能够检测不和谐用户何时发送 URL 链接，无论是视频、网站还是不和谐邀请，并保存链接，是否有任何预先存在的库?

I want to be able to detect when a discord user sends a URL link, whether it be a video, website, or discord invite, and to save the link, are there any pre-existing libraries?

推荐答案

Regex 是我最喜欢的解决方案.

Regex is my favourite solution for this.

    def _match_url(url):
        regex = re.compile(
            "(([w]+:)?//)?(([dw]|%[a-fA-fd]{2,2})+(:([dw]|%[a-fA-fd]{2,2})+)?@)?([dw][-dw]{0,253}[dw].)+[w]{2,63}(:[d]+)?(/([-+_~.dw]|%[a-fA-fd]{2,2})*)*(?(&?([-+_~.dw]|%[a-fA-fd]{2,2})=?)*)?(#([-+_~.dw]|%[a-fA-fd]{2,2})*)?"
        )
        if regex.match(url):
            return True
        else:
            return False
