我正在尝试在 Django 中构建一个登录表单，当用户点击登录时，我希望发送用户名和密码以检查它是哪种类型的用户，因为我的系统有 3 种不同类型的用户。
以下是代码：
views.py
from django.shortcuts import render
from django.views.decorators.csrf import csrf_exempt, csrf_protect
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.models import User
def index(request):
return render(request, "login.html")
@csrf_protect
def auth_login(request):
print("Hello !")
username = request.POST['username']
password = request.POST['password']
user = authenticate(request, username=username, password=password)
group = User.objects.get(username=username).groups.values()[0]['name']
print(username)
print(user)
print(password)
return render(request, "add_form.html")
@csrf_protect
def logout(request):
logout(request)
登录.html - (我有一个简单的引导登录表单(

我在论坛上提到了不同的答案，我也尝试过这个点击这里
但它不会进入函数并在终端上打印第一个语句。 我无法调试它，也无法理解这里的问题。
提前谢谢。
编辑：粘贴整个HTML文件供您尝试以及Django控制台
您可能需要在文件urls.py中更改它：
url(r'^', views.index, name='Home'),
自
path(r'^', views.index, name='Home'),
来自有关url功能的官方文档
此函数是django.urls.re_path((的别名。它可能会在将来的版本中被弃用。
您的url函数匹配任何字符串，因此所有请求都将发送到views.py文件中的index函数。
