Python Django send_mail返回SMTPConnectError

我正在尝试使用Django send_email、smtp和gmail发送电子邮件。但是，代码返回SMTPConnectError（-1，b”）

My 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

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)

My views.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

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)

回溯：

Traceback (most recent call last):
File "<console>", line 1, in <module>

self.connection = connection_class(self.host, self.port, **connection_params
)
File "C:\Python34\lib\smtplib.py", line 244, in __init__
raise SMTPConnectError(code, msg)
smtplib.SMTPConnectError: (-1, b")

它工作正常。而且，当我使用虚拟后端时，它不会显示错误

我尝试过使用SSL而不是TLS，允许gmail中的应用程序不太安全，关闭了防火墙，还尝试过其他与通过django发送电子邮件相关的stackoverflow帖子，但都没有效果。我不知道错误是什么。请帮助我。提前感谢。

gmail帐户需要此：

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'your-username@gmail.com'
EMAIL_HOST_PASSWORD = 'your-password'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

然后通过以下方式测试其工作：

python manage.py shell

from django.core.mail import send_mail
send_mail('testEmail', 'hi', 'Youremail@email.com', ['Emailtest@email.com'])

如果您没有使用gmail帐户，但仍然遇到问题，那么只需尝试将EMAIL\u HOST\u用户和EMAIL\u HOST\u密码添加到您的帐户中即可。如果仍然存在问题，可能是您的网络阻止了您。操作系统或路由器上的防火墙。

您可能需要解锁Captcha以使Django能够为您发送电子邮件：非常有效。谢谢。不需要专业人士问题。祝你好运！（：谢谢你的回答。我已经尝试了所有这些。问题现在已经解决。它与我们学院的网络有关。我没有发布解决方案，因为这是一个非常学院特有的问题。
