使用 Django 通过 gmail 发送电子邮件时出现 ConnectionRefusedError

Question

我正在尝试通过我的 Gmail 帐户为我的 Django 应用程序发送电子邮件。我在 settings.py 文件中使用以下配置。

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST_USER = 'username@gmail.com'
EMAIL_HOST = 'smtp.gmail.com' # tried smtp-relay.gmail.com also
EMAIL_PORT = '587'
EMAIL_USE_TLS = True
EMAIL_HOST_PASSWORD = 'Gmail password / app password' 

这方面的导入声明：

from django.core.mail import send_mail, EmailMessage
from django.conf import settings

以下是我的观点功能：

    message = EmailMessage(subject=email_subject, body=email_message, from_email=settings.EMAIL_HOST_USER,  to=[email, 'username@gmail.com'])
    message.send(fail_silently=False)

我也试过这个：

send_mail(email_subject, email_message , settings.EMAIL_HOST_USER, [email, 'username@gmail.com'] , fail_silently=False, )

非常感谢任何帮助。请注意，我已经尝试过：

1. 在 Gmail 中启用不太安全的应用按钮
2. 然后，我禁用了安全性较低的应用，启用了 2 因素身份验证并使用 Google 的应用密码选项。

这是完整的回溯：

Answer 1

应该是

EMAIL_PORT = 587

但不是

EMAIL_PORT = '587'

端口号是整数而不是字符串。
