django 【认证】

一、验证

 　　1.views.py

from django.contrib.auth.decorators import login_required
from django.contrib.auth import authenticate,login,logout


@login_required
def index(request):
    return render(request,"index.html")


def account_logout(request):
    logout(request)
    return redirect("/")

def account_login(request):

    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")
        user = authenticate(username=username,password=password)
        if user:
            print('user login scuess',user)
            login(request,user)
            return  redirect(request.GET.get('next') or '/')  # bug,
    return render(request,'login.html')

　　2.settings.py

LOGIN_URL = "/account/login/"


或者写在views.py
@login_required(LOGIN_URL = "/account/login/")
def index(request):
    return render(request,"index.html")
