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")
