    print(request.GET)

    print(request.GET.get("name"))
    print(request.POST)
    print(request.path)
    print(request.get_full_path)

    return   HttpResponse("INDEX")


def login(request):

    if request.method =="POST":
        user = request.POST.get("user")
        pwd = request.POST.get("pwd")

        if user == "alex" and pwd =="123":
            return  redirect("/index/")
