在這里，兩個(gè)URL表達(dá)式都指向了同一個(gè)視圖 views.page ，但是第一個(gè)表達(dá)式?jīng)]有傳遞任何參數(shù)。 如果匹配到了第一個(gè)樣式， page() 函數(shù)將會(huì)對(duì)參數(shù) num 使用默認(rèn)值 "1" ，如果第二個(gè)表達(dá)式匹配成功， page() 函數(shù)將使用正則表達(dá)式傳遞過(guò)來(lái)的num的值。（注：我們已經(jīng)注意到設(shè)置默認(rèn)參數(shù)值是字符串 `` ‘1’`` ，不是整數(shù)`` 1`` 。為了保持一致，因?yàn)椴蹲浇o`` num`` 的值總是字符串。每個(gè)被捕獲的參數(shù)將被作為純Python字符串來(lái)發(fā)送。

5、包含其他urls

from django.conf.urls.defaults import *

urlpatterns = patterns('',
    (r'^weblog/', include('mysite.blog.urls')), #注意這里不使用$來(lái)匹配結(jié)束，因?yàn)槁窂胶竺娴膮?shù)可能會(huì)被包含urls中的patterns匹配
    (r'^photos/', include('mysite.photos.urls')),
    (r'^about/$', 'mysite.views.about'),
)

urlpatterns = patterns('',
    (r'^(?P<username>\w+)/blog/', include('foo.urls.blog')),
)

urlpatterns = patterns('',
    (r'^blog/', include('inner'), {'blogid': 3}),
)
