urls.py:URL dispatcher (routing configuration file)
URL configuration (URLconf) is like the directory of the website supported by Django . Its essence is a mapping table between a URL pattern and the viewfunction to be called for that URL pattern. In this way, you tell Django to call this code for this URL and call that code for that URL. The loading of the url starts from the configuration file.
Two forms of urlpatterns
If there is no prefix, use the list (recommended method)
URL pattern
urlpatterns = [ url(正则表达式, view函数, 参数, 别名, 前缀), ]
Parameter description:
- ##Regular expression: Regular expression
- view function: a callable
object, usually a view function or a string specifying the view function path
- Parameters: optional default parameters (dictionary form) to be passed to the view function
- Alias: an optional name parameter
- Prefix: Path prefix
URL parser
Usually a URL parser corresponds to a URL configuration module, which can contain multiple URL patterns. Multiple other URL splitters can also be included. Through this inclusion structure design, Django's hierarchical analysis of UR is realized.The URL decomposer is the key to Django's decoupling of apps and projects. The URL configuration module, usually operated by the
include method, will eventually be dieted into a URL decomposer.
Examples of common URL writing methods regex
url(r'test/\d{2}/$', views.test) # test/66
url(r'test/(?P<id>\d{2})/$', views.test)
url(r'test2/(?P<id>\d{2})/(?P<key>\w+) /$', views.test)Thank you for reading, I hope it can help everyone, thank you for your support of this site!
