利用Django开发网站，可以设计出非常优美的url规则，如果url的匹配规则（包含正则表达式）组织得比较好，view的结构就会比较清晰，比较容易维护。
最简单的形式
<code>
from django.conf.urls import patterns, url
urlpatterns = patterns('',
url(r'^articles/2003/$', 'news.views.special_case_2003'),
url(r'^articles/(\d{4})/$', 'news.views.year_archive'),
url(r'^articles/(\d{4})/(\d{2})/$', 'news.views.month_archive'),
url(r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'news.views.article_detail'),
)</code>
其中，正则表达式中组匹配出来的结果可以作为positional parameters传递给view.
如果url是www.yourdomain/articles/2005/，则会匹配第二条规则，执行news.views.year_archive('2005').
注意点
域名部分会被过滤掉
articles的前面不需要添加/，因为前序url的末尾一定会有/
任何组匹配的变量，都会议字符串的形式传递给view, 虽然通过(\d{4})匹配出了2005，但2005任然会被当做字符串传递给year_archive
利用named group来传递参数
可以通过以下形式为特定的组指定一个名称.
urlpatterns = patterns('',
url(r'^articles/2003/$', 'news.views.special_case_2003'),
url(r'^articles/("htmlcode">
# URLconf
from django.conf.urls import patterns, url
urlpatterns = patterns('',
url(r'^blog/$', 'blog.views.page'),
url(r'^blog/page("1"):
# Output the appropriate page of blog entries, according to num.
指定view前缀(提取公因式)
patterns函数的第一个参数即是view的前缀
from django.conf.urls import patterns, url
urlpatterns = patterns('news.views',
url(r'^articles/(\d{4})/$', 'year_archive'),
url(r'^articles/(\d{4})/(\d{2})/$', 'month_archive'),
url(r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'article_detail'),
)
指定多个view前缀
urlpatterns = patterns('myapp.views',
url(r'^$', 'app_index'),
url(r'^("htmlcode">
from django.conf.urls import include, patterns, url
urlpatterns = patterns('',
# ... snip ...
url(r'^comments/', include('django.contrib.comments.urls')),
url(r'^community/', include('django_website.aggregator.urls')),
url(r'^contact/', include('django_website.contact.urls')),
# ... snip ...
)
当然也可以直接include其它patterns
from django.conf.urls import include, patterns, url
extra_patterns = patterns('',
url(r'^reports/("htmlcode">
from django.conf.urls import patterns, url
urlpatterns = patterns('blog.views',
url(r'^blog/("htmlcode">
from django.conf.urls import patterns, url
from mysite.views import archive, about, contact
urlpatterns = patterns('',
url(r'^archive/$', archive),
url(r'^about/$', about),
url(r'^contact/$', contact),
)
