当我尝试注册用户时，/ accounts / register /中的ConnectionRefusedError

如何解决当我尝试注册用户时，/ accounts / register /中的ConnectionRefusedError

伙计们。当尝试在我的网站上重新注册用户时，我遇到此错误。我是初学者。我也没有收到激活邮件。请参见下面的代码。你有遇到这样的问题吗？我该如何解决？我尝试使用不同的方法，但无济于事。

在我的Utility.py文件中

from django.template.loader import render_to_string
from django.core.signing import Signer
from bboard.settings import ALLOWED_HOSTS


signer = Signer()

def send_activation_notification(user):
    if ALLOWED_HOSTS:
        host = 'http://' + ALLOWED_HOSTS[0]
    else:
        host = 'http://localhost:8000'
    context = {'user':user,'host':host,'sign':signer.sign(user.username)}
    subject = render_to_string('email/activation_letter_subject.txt',context)
    body_text = render_to_string('email/activation_letter_body.txt',context)
    user.email_user(subject,body_text)

在views.py

中

    def user_activate(request,sign):
    try:
        username = signer.unsign(sign)
    except BadSignature:
        return render(request,'main/bad_signature.html')
    user = get_object_or_404(AdvUser,username=username)
    if user.is_activated:
        template = 'main/user_is_activated.html'
    else:
        template = 'main/activation_done.html'
        user.is_active = True
        user.is_activated = True
        user.save()
    return render(request,template)

在settings.py

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_PORT = 25
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_USE_TLS = False
DEFAULT_FROM_EMAIL = 'webmaster@localhost'

ALLOWED_HOSTS = [
    '127.0.0.1',]

如果我需要提供其他任何东西，请告诉我。

我看到此错误

解决方法

检查本地主机上端口25上是否运行SMTP。如果没有，则需要使用有效的SMTP设置。

首先要进行调试的是将电子邮件后端切换到控制台：https://docs.djangoproject.com/en/3.1/topics/email/#console-backend
