使用电子邮件注册，Django 2.0 [英] Registration using e-mail, Django 2.0

问题描述

我只是一个初学者，所以在制作第一个项目时遇到了一些问题。我在视图中有代码：

I'm just a beginner, so i got some questions making my first project. I've got code in views:

def signup(request):
if request.method == 'POST':
    form = SignupForm(request.POST)
    if form.is_valid():
        user = form.save(commit=False)
        user.is_active = False
        user.save()
        current_site = get_current_site(request)
        mail_subject = 'Активация'
        message = render_to_string('acc_active_email.html', {
            'user': user,
            'domain': current_site.domain,
            'uid':urlsafe_base64_encode(force_bytes(user.pk)),
            'token':account_activation_token.make_token(user),
        })
        print(message) # здесь я смотрю какое сообщение отправляю

        to_email = form.cleaned_data.get('email')
        email = EmailMessage(
                    mail_subject, message, to=[to_email]
        )
        email.send()
        return HttpResponse('Пожалуйста, подтвердите адрес электронной почты')
else:
    form = SignupForm()
return render(request, 'signup.html', {'form': form})


def activate(request, uidb64, token):
    try:
        uid = force_text(urlsafe_base64_decode(uidb64))
        user = User.objects.get(pk=uid)
    except(TypeError, ValueError, OverflowError, User.DoesNotExist):
        user = None
    if user is not None and account_activation_token.check_token(user, token):
        user.is_active = True
        user.save()
        login(request, user)
        # return redirect('home')
        return HttpResponse('Thank you for your email confirmation. Now you can login your account.')
    else:
        return HttpResponse('Activation link is invalid!')

此代码来自网址：

from . import views
from django.urls import path

urlpatterns = [
    path('', views.signup, name='signup'),
    path('activate/?P<uidb64>[0-9A-Za-z_\-]+/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',
        views.activate, name='activate'),
]

问题是我总是在电子邮件中收到无效的URL。
我认为这与新的路径功能有关，可以使用的是

The problem is that i always get invalid URL in my email. I think it is about new 'path' function, which may be used is

<int:uidb64>

但不是很确定。
感谢您的帮助！

but not really sure. Thank for your help!

推荐答案

您不能使用 [0- 9A-Za-z_：//-] + ，当您使用 path（） 。如果要使用正则表达式，请使用 re_path （与旧版Django中的 url（）相同）。

You can't use regexes like [0-9A-Za-z_\-]+ when you use path(). If you want to use regexes, then use re_path (which works the same as url() from older versions of Django).

使用 path（）时，可以使用内置的路径转换器。您不能使用< int：uidb64> ，因为uidb可以包含 A-Za-z ，连字符，和下划线，而不仅仅是数字。

When you use path(), you can use one of the built-in path converters. You can't use <int:uidb64>, because uidb can contain A-Za-z, hyphens, and underscores, not just digits.

对于您的 uidb64 和令牌，我认为 slug 是Django中最适合的路径转换器。

For your uidb64 and token, I think slug is the most suitable of the path converters included in Django.

path('activate/<slug:uidb64>/<slug:token>/', views.activate, name='activate'),

这将匹配您的正则表达式不允许的子段和令牌，但是只要您 check_token 方法为这些无效值返回 False ，并且不会引发错误。

This will match slugs and tokens which your regex wouldn't allow, but this isn't a problem as long as your check_token method returns False for these invalid values and does not raise an error.
