Django URL 模式语法 - 原始字符串

Question

What is the difference between:

path('index/', views...

And

path(r'^index/$', views...

I use the first example but I see everyone using the raw string syntax in examples I look up. Are there any differences between the way Django handles the two examples?

Answer 1

The path method is the full match method , so when your path will be exactly as described, you will have the possibility to handle the request with the view that you've described.

The re_path allows you more control with regular expressions. Let's extend your example r"^index/?$" , here "?" sign allows the user to use the trailing slash "/" at the end of the URL or not use.

You can play with regexp here: https://regex101.com

The Django documentation about re_path is here: https://docs.djangoproject.com/en/dev/topics/http/urls/#using-regular-expressions

The business needs could be very complex and maybe you won't be able to make a match for a needed URL format with just the path features, but in 99% this option will be enough.
