Django also has a solution that doesn't just use regex. It is django.utils.html.urlize(). I found this to be very helpful, especially if you happen to be using django.
Django 也有一个不仅仅使用正则表达式的解决方案。它是django.utils.html.urlize()。我发现这非常有帮助，尤其是当您碰巧使用 django 时。
You can also extract the codeto use in your own project.
您还可以提取代码以在您自己的项目中使用。
