urls.py-路由

• URL和函数对应关系

from django.conf.urls import url
from django.contrib import admin
from django.shortcuts import HttpResponse,render

def index(request):    #接受参数
    return HttpResponse("欢迎光临")

def home(request):     #接受参数
    return render(request,'home.html')  #访问home目录，跳转到路径

def login(request):    #接受参数
    return render(request,'login.html')  #访问home目录，跳转到路径

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^index/', index),
    url(r'^home/', home),
    url(r'^login/', login),
]
