Urls解耦合：将存放在主文件夹中的urls.py文件中的路径进行分块（移动至相应的应用文件夹中）
"""myWebSite URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.1/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
原urls.py文件：
from django.contrib import admin
from django.urls import path,include
from django.conf.urls import url
from blog import views
urlpatterns = [
path('admin/', admin.site.urls),
path('show_time/', views.show_time),
#根据该文件上方的注释文档完成归类
url(r'blog/', include('blog.urls')),
# 下面url被解耦合，将含有srticle的部分重新定位于相应的应用(blog)下
# url(r'article/2004$', views.article_year),
# url(r'article/(?P<year>\d{4})/(?P<month>\d{2})', views.article_year_month),
#前端使用的别名
url(r"register",views.register,name="reg"),
]blog文件夹下新建urls.py文件：
from blog import views
from django.conf.urls import url
urlpatterns = [
url(r'article/2004$', views.article_year),
url(r'article/(?P<year>\d{4})/(?P<month>\d{2})', views.article_year_month),
]访问路径时需要添加应用/应用文件夹的名称（Django默认开8000端口）：
http://localhost:8000/blog/article/2019/06
