message = render_to_string('acc_active_email.html', {'用户':用户，域":current_site.domain，'uid': urlsafe_base64_encode(force_bytes(user.pk)).decode(),'token': account_activation_token.make_token(user),})请参阅Django 2.0 发行说明 了解更多信息.在 Django 2.2+ 中，urlsafe_base64_encode 返回一个字符串，所以不需要解码.message = render_to_string('acc_active_email.html', {'用户':用户，域":current_site.domain，'uid': urlsafe_base64_encode(force_bytes(user.pk)),'token': account_activation_token.make_token(user),})使用 force_text 应该可以编写与 Django from django.utils.encoding import force_textmessage = render_to_string('acc_active_email.html', {'用户':用户，域":current_site.domain，'uid': force_text(urlsafe_base64_encode(force_bytes(user.pk))),'token': account_activation_token.make_token(user),})一旦您放弃对 Django 的支持，您就可以放弃 force_text 并使用第二个代码片段2.2.I can't understand why my code doesn't work. Before it worked, but now, when I run the server and test, the code does not work.When the user is registering, I send him activation email, like this:def send_activation_email(serializer, request, user): current_site = get_current_site(request) 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), }) mail_subject = 'Activate your blog account.' to_email = serializer.data['email'] email = EmailMessage(mail_subject, message, to=[to_email]) email.send()acc_active_email.html{% autoescape off %}Hi {{ user.username }},Please click on the link to confirm your registration,http://{{ domain }}{% url 'activate' uidb64=uid token=token %}{% endautoescape %}and my url file.. url(r'^activate/(?P<uidb64>[0-9A-Za-z_-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', views.activate_account, name='activate'),..but I have this error:Exception Type: NoReverseMatchException Value:Reverse for 'activate' with keyword arguments '{'uidb64': b'NDM', 'token': '4qz-8f770502bd8b02786da9'}' not found. 1 pattern(s) tried: ['activate/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$']highlights this line http://{{ domain }}{% url 'activate' uidb64=uid token=token %} 解决方案 In Django 2.0 and 2.1 you should call decode() after base64 encoding the uid, to convert it to a string:message = render_to_string('acc_active_email.html', { 'user': user, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)).decode(), 'token': account_activation_token.make_token(user),})See the note in the Django 2.0 release notes for more info.In Django 2.2+, urlsafe_base64_encode returns a string, so there is no need to decode.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),})It should be possible to write code that is compatible with Django <= 1.11, 2.0-2.1, and 2.2+, by using force_text. Note the following is untested.from django.utils.encoding import force_textmessage = render_to_string('acc_active_email.html', { 'user': user, 'domain': current_site.domain, 'uid': force_text(urlsafe_base64_encode(force_bytes(user.pk))), 'token': account_activation_token.make_token(user),})You can drop the force_text and use the second code snippet once you drop support for Django < 2.2. 这篇关于NoReverseMatch 与关键字参数 uidb64 与 Django 2.0的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
