django自带的登录验证功能

django自带的验证机制

from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login, logout  #登入和登出

from django.contrib.auth.decorators import login_required  # 验证用户是否登录

def acc_login(request):

if request.method == "POST":
username = request.POST.get("username")
password = request.POST.get("password")

user = authenticate(username=username,password=password)  # 类型为<class 'django.contrib.auth.models.User'>

# print(type(models.Customer.objects.get(name="赵凡")))
# print(user,type(user))
if user:

login(request,user)  # 验证成功之后登录
return  redirect('/crm')

return render(request, "login.html")

def acc_logout(request):

logout(request)  # 登出

return redirect("/login")

必须登录之后才能访问页面

from django.contrib.auth.decorators import login_required

@login_required  # 加上这个装饰器就是限制必须登录才能执行这个函数
def dashboard(request):
print(request.user)

return render(request, "crm1/dashboard.html")

如果加了@login_required,页面跳转会有问题,解决方法如下

/login/

LOGIN_URL = "/login/"
