django - Cookiecutter - Django：Anymail [SES] boto3 区域错误

Question

我正在尝试将 Cookiecutter Django 项目部署到 AWS(EC2)。拥有此凭证的 AWS 用户拥有完整的 S3、SES 和 SNS 策略。EC2 服务器还具有具有完整 SES/S3 策略的角色。

在 envs 的生产文件中，我有这样设置的密钥。

DJANGO_AWS_ACCESS_KEY_ID=xxxxxxxxx
DJANGO_AWS_SECRET_ACCESS_KEY=xxxxxxxxxx
DJANGO_AWS_STORAGE_BUCKET_NAME=xxxxxxxxxx

在我的设置中

AWS_S3_REGION_NAME = env("DJANGO_AWS_S3_REGION_NAME", default=None)
AWS_ACCESS_KEY_ID = env("DJANGO_AWS_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = env("DJANGO_AWS_SECRET_ACCESS_KEY")
AWS_STORAGE_BUCKET_NAME = env("DJANGO_AWS_STORAGE_BUCKET_NAME")
EMAIL_BACKEND = "anymail.backends.amazon_ses.EmailBackend"
ANYMAIL = {}

一切都很好，直到项目尝试使用 SES 发送电子邮件并崩溃并出现以下错误。

到目前为止，我已经尝试过：

将 DJANGO_AWS_S3_REGION_NAME 添加到环境中的生产文件中 - 没有结果
使用 aws cli 在 aws config 中添加区域 - 无结果
使用凭据和区域覆盖 ANYMAIL ={} 中的设置 - 没有结果
制作一个空白项目，只需添加 aws 凭据而不更改其他任何内容 - 没有结果
在另一个项目上手动创建具有相同凭据的 boto3.session.client 并发送邮件 - 它可以工作

这是错误。'NoneType' 对象的第二部分没有属性 'send_raw_email' 在此之后重复了很多。

我会很感激任何意见。我没主意了。谢谢！

您可能已经知道，问题在于 boto3 不知道您要在哪个 AWS 区域运行：

botocore.exceptions.NoRegionError: You must specify a region.

区域名称来自 boto3 配置。来自Anymail 的 SES 文档：

您必须确保为 boto3 配置了具有必要 IAM 权限的 AWS 凭证。做这件事有很多种方法; 有关选项，请参阅Boto 文档中的凭据。通常，适用于 EC2 实例、标准 Boto 环境变量或共享 AWS 凭证文件的 IAM 角色将是合适的。对于更复杂的情况，使用 Anymail 的AMAZON_SES_CLIENT_PARAMS设置来自定义 Boto 会话。

似乎您可能会尝试混合使用一些“几种方式”来提供 boto3 凭据，这可能会导致混淆。

请注意，您的AWS_*Django 设置不起作用。boto3 不知道 Django 设置。Anymail 的 SES 设置文档描述了 Anymail 将传递给 boto3 的 Django 设置。（而且AWS_S3_REGION_NAME无论如何都不会相关，因为 S3 与 SES 的服务不同。我猜这些AWS_*Django 设置可能适用于其他一些应用程序，也许是 django-storages。）

如果您想在 settings.py 中专门为 Anymail 提供 AWS 凭证，您可以使用 Anymail 的AMAZON_SES_CLIENT_PARAMS设置来实现。例如：

# (Be sure to add DJANGO_AWS_REGION_NAME to your env to use this example)
ANYMAIL = {
    "AMAZON_SES_CLIENT_PARAMS": {
        "aws_access_key_id": env("DJANGO_AWS_ACCESS_KEY_ID"),
        "aws_secret_access_key": env("DJANGO_AWS_SECRET_ACCESS_KEY"),
        "region_name": env("DJANGO_AWS_REGION_NAME"),
    },
}
