django中的url模式正则表达式

Question

This is aa basic question but I'm having trouble finding the answer in in docs:

Lets say I have a url like:

http://example.com/part1/part2

and I have:

urlpatterns = patterns('',
    # Examples:
    url(r'^$', 'xxx', name='yyy'),

)

What part of the url string above is attempted to be matched by the regex between ^ and $ ?

I've read through numerous sources and docs including:

• https://docs.djangoproject.com/en/1.6/intro/tutorial03/
• https://docs.djangoproject.com/en/1.6/ref/urlresolvers/#module-django.core.urlresolvers
• http://www.djangobook.com/en/2.0/chapter03.html .

Answer 1

This is stated in the documentation clearly:

The URLconf searches against the requested URL, as a normal Python string. This does not include GET or POST parameters, or the domain name.

For example, in a request to http://www.example.com/myapp/ , the URLconf will look for myapp/.

In a request to http://www.example.com/myapp/?page=3 , the URLconf will look for myapp/.

The URLconf doesn't look at the request method. In other words, all request methods – POST, GET, HEAD, etc. – will be routed to the same function for the same URL.

In your case, part1/part2 string would be searched against.
