login.html

from django.db import models
from django.contrib.auth.models import User

class Account(models.Model):
    """
    堡垒机账户
    1.扩展
    2.继承
    """
    user = models.OneToOneField(User, models.CASCADE)
    name = models.CharField(max_length=64)

models.py

LOGIN_URL = '/login/'

settings.py

from django.shortcuts import render,redirect,HttpResponse
from django.contrib.auth import authenticate,login,logout
from django.contrib.auth.decorators import login_required

# @login_required(login_url='/login/')  # 单独添加login页面的url
# 或在settings.py设置全局LOGIN_URL = '/login/'
@login_required
def index(request):
    return HttpResponse("成功登录index页面！")
    return render(request,"index.html")

def acc_login(request):
    error = ''
    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")
        user = authenticate(username=username,password=password)  # 认证
        if user:
            login(request,user)  # 登录
            return redirect(request.GET.get('next') or "/index/")  # 若有next字段，则跳转到该url，否则index页面
        else:
            error = "Wrong username or password"

    return render(request,"login.html",{"error":error})

@login_required
def acc_logout(request):
    logout(request)  # 登出
    return redirect("/login/")

views.py

结果：

单独登录login页面

直接访问index页面，views里的login_required装饰器会跳转到login页面，同时会带有?next=/index/字段的url

此处需在login函数里配置

return redirect(request.GET.get('next') or "/index/")

成功登录
