django 中的 url.py，^ 有什么作用? [英] url.py in django, what does ^ do?

问题描述

所以我刚开始学习 django，我目前正在处理 urls.py 文件.我想知道是否有人可以向我解释网址开头的^"是什么?如果我说的没有意义，我也发布了一些代码.

So ive just started learning django and im currently messing around with the urls.py file. I was wondering if someone could explain to me what the "^" at the start of the url does? I posted some code too if what I said doesnt make sense.

url(r'^$', post_timeline),

推荐答案

在 urls.py,

^ means the start of the URL string and $ is the end of the URL.

例如:

from django.conf.urls import url, patterns

urlpatterns = [
    url(r'^some_base_path/', include('your_app.urls', namespace='your_app')),
]

在你的应用的 urls.py 中:

And in urls.py of your app :

urlpatterns = patterns(
    url(r'^some_url$', your_app.some_view),

)

在第二个 URL 中，r'^some_url$' 表示从 some_url 开始，$ 表示该 URL 到此结束.不能再添加其他 URL 字符串.

Here in the second URL, r'^some_url$' means start at some_url and $ means that the URL ends here.NO further URL string can be added to it.
