url分发

第一步 主文件夹urls

"""mysite01 URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.11/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url,include
from django.contrib import admin
from blog import views

urlpatterns = [


    url(r'admin/', admin.site.urls),三角是上标，pycharm里没有
    url(r'show_time/', views.show_time),
    url(r'blog/', include('blog.urls')),多了一个路由http;//..../blog/register
这样访问了

]

2 blog应用里新建一个urls 分发

from django.conf.urls import url, include

from blog import views

urlpatterns = [

    url(r'article/(\d{4})$', views.article_year),  # $代表以某4位数结尾，如2001，只以他结尾
    # 无命名分组形式访问
    # \d一个占位符，占4个如2004，
    # r代表正则
    url(r'article/(?P<year>\d{4})/(?P<month>\d{2})', views.article_year_month),
    # 命名分组，就是加上?P<>这种固定格式，且尖括号里内容为函数参数名
    url(r'register', views.register, name="reg"),  # 别名reg,以后用它就行
]
