我正在尝试通过电子邮件激活用户，电子邮件可以正常工作，编码也可以正常工作，我使用了Django1.11的一种方法，这个方法之前成功地运行过。
在Django1.11中，以下内容成功解码为28，其中uidb64 = b'Mjg'
force_text(urlsafe_base64_decode(uidb64))
在 Django 2（版本号为 2.0.0 final）中，上述代码的解码功能不可用并会导致错误。
django.utils.encoding.DjangoUnicodeDecodeError: 'utf-8' codec can't decode byte 0xc8 in position 1: invalid continuation byte. You passed in b'l\xc8\xe0' (<class 'bytes'>)
我也发表一下我的看法，以防万一。
from django.utils.encoding import force_bytes, force_text
from django.utils.http import urlsafe_base64_encode, urlsafe_base64_decode
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()
# auth_login(request, user)
message = render_to_string('user_activate_email.html', {
'user': user,
'domain': Site.objects.get_current().domain,
'uidb64': urlsafe_base64_encode(force_bytes(user.pk)),
'token': account_activation_token.make_token(user),
})
mail_subject = 'Activate your blog account.'
to_email = form.cleaned_data.get('email')
email = EmailMessage(mail_subject, message, to=[to_email])
email.send()
messages.info(
request, 'Activation link has been sent to your email!')
# return redirect('home')
return render(request, 'index.html')
else:
form = SignUpForm()
return render(request, 'user_action.html', {'form': form})
def activate(request, uidb64, token):
try:
import pdb;
pdb.set_trace()
uid = urlsafe_base64_decode(uidb64).decode()
user = User.objects.get(pk=uid)
except(TypeError, ValueError, OverflowError):
user = None
if user is not None and account_activation_token.check_token(user, token):
user.refresh_from_db()
user.is_active = True
user.save()
auth_login(request, user)
messages.info(request, 'Your account has been activated successfully!')
return redirect('events:home')
else:
messages.info(
request, 'Activation link is invalid or has been activated')
return redirect('events:home')
PS：在我与CBV合作之前，这只是一次试验。
