django之基于cookie和装饰器实现用户认证

示例1

 # Create your views here.
 user = "a"
 pwd = "a"
 def login(request):
     if request.method =="GET":
         return render(request,"login.html")
     elif request.method == "POST":
         u = request.POST.get("user")
         p = request.POST.get("password")
         print(u)
         print(p)
         if u ==user and p ==pwd:
             res = redirect("/index")
             res.set_cookie('user',u,max_age=5)   #设置cookie，关闭浏览器cookie失效。max_age=5表示5秒后cookie失效，需要重新登录
             return res
         else:
             return  render(request,"login.html")
 def index(request):
     v = request.COOKIES.get("user")
     if v:
         return render(request,"index.html",{"current_user":v})
     else:
         return redirect("/login")
