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")
