AWS S3存储桶Django 3.0用户配置文件图像上传访问错误

Question

INTRO

我按照建议遵循this指南，这里是guide's GitHub repo。
我也创建了一个AmazonS3FullAccess
我正在使用指南的第三个示例“ 混合公共资产和私有资产”，其中包含静态，媒体公共，媒体，私有版本。
如果用户登录（本地开发环境），他将从网站上载文件，但是他不能仅从AWS S3管理网站从网站上访问它们。
当前，由于指南中的内容，我正在阻止所有公共访问（AWS S3管理面板设置）
我已将这些行从this other guide添加到我的CORS配置编辑器中>

<?xml version="1.0" encoding="UTF-8"?>

打开了对我来说更本地的中央EU服务器。没有用，我遇到了同样的错误。

到目前为止我尝试过的事情

在一段时间之间，它创建了AWS链接，并且还将文件添加到了本地“ media”文件夹。但是由于我已经删除了“媒体文件夹”，并且它仅创建URL链接，并且实际上将它们上传到S3存储桶
我在aws论坛上找到了相同的question，但尚未得到答案
访问权限Django + AWS S3 Bucket: Authenticated Access to S3 Bucket（我不知道此答案https://stackoverflow.com/a/21614550/10270590）
“使用AWS4-HMAC-SHA256”
- 将S3主机的区域指定为正确的用法https://github.com/aws/aws-sdk-js/issues/829
- 查找您所在地区的网站-https://docs.aws.amazon.com/general/latest/gr/rande.html
- 我也收到建议，“大多数新区域仅支持AWS4-HMAC-SHA256-如果您的代码不支持此身份验证方案，并且仅创建了“ v2签名”
- 我在使用测试机的欧盟-我在美国建立了S3存储桶

这是我已添加到设置based on中的确切代码，以及原始指南的代码。当我切换图像时，它可以工作，但是当我离开配置文件设置并返回时，图像消失并给出原始错误）：

AWS_S3_HOST = "s3.eu-central-1.amazonaws.com"
S3_USE_SIGV4 = True
AWS_S3_REGION_NAME = "eu-central-1"
