某些 API 无法通过 IBM 云存储对象 S3 API 访问

Question

我指的是以下网址上的信息。https://ibm-public-cos.github.io/crs-docs/about-compatibility-api#operations-on-buckets如上述 URL 所述，有 3 个与 IBM 云存储对象相关的对象 API 可供访问。但是，IBM CSO API 的某些 API 无法访问，例如 PUT Bucket ACL 和 GET Bucket ACL，并在使用 POSTMAN 访问它们时收到 403 错误消息。我需要有关如何访问这些 API 的信息？请提供与此相关的任何信息。任何帮助将不胜感激。

截至今天，IBM COS 支持 GET/PUT 存储桶 ACL。 如果您使用的是 Postman，下面是这些 Postman 转储的示例(显然您需要计算 Authorization 标头并使用您自己的所有信息，这只是一个教育示例(：

根据您对"云存储对象 API"的引用，我可以猜测您可能正在使用 IBM COS 的本地安装。请给我发一封电子邮件 nicholas.lange[at]ibm.com 以便我们讨论您正在寻找什么。
