路由控制器：
from django.urls import path # 字符串路由
from django.urls import re_path # 正则路由，会把url地址看成一个正则模式与客户端的请求url地址进行正则匹配
# path和re_path 使用参数一致.仅仅在url参数和接收参数时写法不一样
基本使用：
from django.contrib import admin
from django.urls import path,re_path
from app01 import views
urlpatterns = [
path('admin/', admin.site.urls),
path(r'^articles/2003/$', views.special_case_2003),
re_path(r'^articles/([0-9]{4})/$', views.year_archive),
re_path(r'^articles/([0-9]{4})/([0-9]{2})/$', views.month_archive),
## 有名分组，根据名称进行分组，后面方便传参
re_path(r'^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/$', views.month_archive2),
]
路由分发：
- 使用路由分发（include），让每个app目录都单独拥有自己的 urls
全局urls配置
from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('app01/',include("app01.urls"))
]
app01.urls配置
from django.urls import path
from app01 import views
urlpatterns = [
path('',views.index)
]
views.index配置
from django.shortcuts import render
def index(request):
return render(request,"index.html")
index.html配置
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h3>hello index.........</h3>
</body>
</html>
执行结果：
路由转发器：
- 内置的url转换器并不能满足我们的需求，因此django给我们提供了一个接口可以让我们自己定义自己的url转换器
全局urls配置
from django.contrib import admin
from django.urls import path,register_converter,include
from app01.views import index
class Mobile(object):
regex="1[3-9]\d{9}"
def to_python(self,values):
return values
register_converter(Mobile, "mo")
urlpatterns = [
path("index/<mo:m>",index)
]
app01.views函数index配置
from django.shortcuts import HttpResponse
def index(request,m):
print(":::",type(m))
return HttpResponse(f"hi,{m}用户")
执行结果：
反向解析：
app07/urls.py配置文件
from django.urls import path
from app07.views import order,index
urlpatterns = [
path('index/', index, name="ind"),
path('order/', order, name="ord")
]
模板反向解析：
app07/views.py配置文件
from django.shortcuts import render
def order(request):
return render(request,"order.html")
def index(request):
return render(request,"index.html")
