"[Errno 8] nodename nor servname provided, or not known"使用 django-ses 时

Question

我正在尝试将django-ses插入我的项目中。我按照本教程中列出的说明进行操作： https://kholinlabs.com/the-easiest-way-to-send-emails-with-django

尽管我相信我已经密切关注这些内容，但在发送测试电子邮件时，我收到此错误：

File "/usr/local/Cellar/python/3.6.5_1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/socket.py", line 745, in getaddrinfo
for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known

我已经成功注册了SES并验证了我用来发送的电子邮件。

从 python 控制台或应用发送时会发生此错误。

这些是我的相关设置：

EMAIL_BACKEND = 'django_ses.SESBackend'
AWS_SES_REGION_NAME = 'eu-west-2'
AWS_SES_REGION_ENDPOINT = 'email.eu-west-2.amazonaws.com'
AWS_SES_ACCESS_KEY_ID = '{secret key}'
AWS_SES_SECRET_ACCESS_KEY = '{secret access key}'
AWS_SES_AUTO_THROTTLE = 0.5 

我该如何解决这个问题？

用于发送 emaik 的命令

from django.core.mail import send_mail
send_mail(
'Subject here',
'Here is the message.',
'[e-mail]',
['[e-mail]'],
fail_silently=False,
)

全栈跟踪

Answer 1

socket.gaierror： [errno 8] nodename 或 servname 提供，或未知

这是因为您的应用程序无法访问您的邮件服务器，有一些原因可能会导致此问题，未正确配置 SES、电子邮件服务器端点错误、凭据错误。

因此，您可以按照以下步骤进行计算。

1. 配置您的 SES(验证您的电子邮件/域(并获取 SMTP 凭据。因此，在此步骤中，您已经获得了：

Server Name: email-smtp.<region>.amazonaws.com (e.g: email-smtp.us-west-2.amazonaws.com)
Authentication: Your SMTP credentials.

2. 通过发送测试电子邮件验证您的 SES 配置，请按照以下步骤验证您的 SES 是否已正确配置。

3. 为您的应用程序设置 SES。例如：

AWS_SES_REGION_NAME = 'us-west-2'
AWS_SES_REGION_ENDPOINT = 'email-smtp.us-west-2.amazonaws.com'
AWS_SES_ACCESS_KEY_ID = '{secret key}'
AWS_SES_SECRET_ACCESS_KEY = '{secret access key}'

4. 测试在应用程序上发送电子邮件

---

当您按照上述步骤操作但仍无法发送电子邮件时，您可能需要仔细检查一些内容：

• 您的AWS_SES_ACCESS_KEY_ID和AWS_SES_SECRET_ACCESS_KEY应由您用于执行步骤 2 的 IAM 用户生成。

• AWS_SES_REGION_ENDPOINT是以下 3 个可用终端节点之一，与你选择设置 SES 的区域匹配：

美国东部(弗吉尼亚北部(：email-smtp.us-east-1.amazonaws.com

美国西部(俄勒冈(：email-smtp.us-west-2.amazonaws.com

欧洲(爱尔兰(：email-smtp.eu-west-1.amazonaws.com

希望这有帮助！

Answer 2

我做了相反的事情

sudo scutil --set 主机名 1.0.0.127

然后

须藤纳米/etc/主机

并添加

1.0.0.127

127.0.0.1

欺骗系统返回 127.0.0.1
