Django- [Errno 111] 使用 smtp 时连接被拒绝

【中文标题】Django- [Errno 111] 使用 smtp 时连接被拒绝

【英文标题】：Django- [Errno 111] Connection refused when using smtp

【问题描述】：

我正在开发一个 Django 应用程序，该应用程序具有向用户发送电子邮件的功能。在一个测试用例中，我有一个联系表单，它使用 smtp 通过 gmail 将表单数据作为电子邮件的一部分提交。我禁用了验证码，正如我在this video playlist 中被告知的那样，我一直在关注教程，但是当我单击提交按钮时，出于某种原因，我得到了 [Errno 111]。在看到this 和another SO post 之后，我了解到我需要在实时服务器（而不仅仅是本地主机）上运行该站点才能发送电子邮件。但是，当我在服务器上尝试此操作时，我遇到了与以前相同的错误。我很确定我遵循了所有正确的步骤，那么可能是什么问题？

这是错误回溯：

【问题讨论】：

toemail = ', '.join(to_email) 并将字符串传递给 send_mail

【参考方案1】：

在设置文件中更改此项

EMAIL_HOSTS = 'smtp.gmail.com'
EMAIL_HOSTS_USER = "[e-mail]"

到

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = "[e-mail]"

【讨论】：

谢谢，这似乎解决了一个错误，但现在我遇到了一个类型错误。我用回溯日志编辑了帖子。你知道发生了什么吗？

你能发表你对 /contact/ 的看法吗

我已经添加了答案。试试看。

【参考方案2】：

在您的代码中；

to_email = [from_email, '[e-mail]'] 

是一个列表，您再次在列表中传递 to_email 参数。

改变这个；

send_mail(subject, contact_message, from_email, [to_email], fail_silently = True )

到

send_mail(subject, contact_message, from_email, to_email, fail_silently = True )

【讨论】：

感谢您的新答案。不过，现在似乎存在某种身份验证错误。我刚刚用新的回溯日志更新了帖子。我将 fail_silently 设置为 False，所以我不确定这是否会导致问题。

这似乎是一个单独的问题，所以我再问一个问题，谢谢。
