如何在Django中配置AWS4 S3授权? [英] How to configure AWS4 S3 Authorization in Django?

问题描述

我为Frankfurt区域配置了S3存储桶.尽管我基于Django的服务能够将文件写入存储桶，但是每当它尝试读取文件时，都会出现InvalidRequest错误，提示升级授权机制:

I configurred S3 bucket for Frankfurt region. Though my Django-based service is able to write files to the bucket, whenever it tried to read them there's InvalidRequest error telling to upgrate authorization mechanizm:

<Error>
  <Code>InvalidRequest</Code>
  <Message>
    The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.
  </Message>
  <RequestId>17E9629D33BF1E24</RequestId>
  <HostId>
    ...
  </HostId>
</Error>

此错误的原因是在我不正确的存储后端实现中造成的，还是由存储桶不支持较早的AWS3授权方法引起的?

Is the cause for this error burried in my incorrect implementation of storage backend or is this caused by bucket not supporting older AWS3 method of authorization?

推荐答案

由于您提到了S3Boto3Storage后端，因此我假设您使用的是django-storages，而不是编写自己的实现.有一个设置可以让您指定要使用的签名版本，AWS_S3_SIGNATURE_VERSION = 's3v4'您可以在此处

Since you mentioned the S3Boto3Storage backend, I'm assuming you're using django-storages rather than writing your own implementation. There's a setting that lets you specify which signature version to use, AWS_S3_SIGNATURE_VERSION = 's3v4' you can find the full list of settings for S3 here https://django-storages.readthedocs.io/en/latest/backends/amazon-S3.html#settings
