我的代码：

from django.contrib.auth import authenticate, login
from django.shortcuts import render


def login(request):
   if request.method == "POST":
       user_name = request.POST.get("username", "")
       pass_word = request.POST.get("password", "")
       user = authenticate(user_name, pass_word)
       if user is not None:
           login(request, user)
           return render(request, "index.html")
   elif request.method == "GET":
       return render(request, "login.html", {})
