python – Django send_mail返回SMTPConnectError

我的settings.py文件：

ALLOWED_HOSTS = []
DEFAULT_FROM_EMAIL = 'mygmailid'
SERVER_EMAIL = 'mygmailid'
EMAIL_USE_TLS = True
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'mygmailid'
EMAIL_HOST_PASSWORD = 'myPassword'
EMAIL_PORT = 587

我的views.py文件：

from django.http import HttpResponse
from django.core.mail import send_mail
from smtplib import SMTPConnectError
#rest of the code in between
....
try:
   send_mail('testmail','test content',settings.EMAIL_HOST_USER,['arkaghosh024@gmail.com',fail_silently=False])
except SMTPConnectError as e:
   return HttpResponse(e)

追溯：

Traceback (most recent call last):

raise SMTPConnectError(code,msg)
smtplib.SMTPConnectError: (-1,b")

当我将EMAIL_BACKEND更改为：

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

它工作正常.此外,当我使用虚拟后端时,它不会显示错误.

我尝试过使用SSL代替TLS,允许gmail中安全性较低的应用程序,关闭防火墙,还尝试了其他与通过django发送电子邮件相关的stackoverflow帖子,但没有任何效果.我不知道错误是什么.请帮我.提前致谢.
