cookie实现访问index无法访问必须从login走，返回固定的session值,

一个浏览器登陆之后会保存用户名密码，可以直接访问index,换个浏览器访问index就无法访问

urls

from django.conf.urls import url
from django.contrib import admin
from app import views

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

views

from django.shortcuts import render,redirect

# Create your views here.
def login(req):
    print("COOKIES",req.COOKIES)
    if req.method=="POST":
        name=req.POST.get("user")
        pwd=req.POST.get("pwd")
        if name=="tom"and pwd==123:
            ret=redirect("index.html")
            ret.set_cookie("username","name")
            return ret
    return render(req,"login.html")

def index(req):
    if req.COOKIES.get("username",None)=="name":

        name="tom"
        return render(req,"index.html",locals())
    else:
         return redirect("login.html")
