我可以将哪些变量类型添加到 s3 对象的元数据中？
What variable types can I add to an s3 objects' metadata?
我可以将哪些常见类型添加到 S3 对象的元数据中？整数、浮点数、海峡、布尔等...?
所以我假设，根据 this 它们必须是字符串类型
You can assign user-defined metadata to an object. User-defined
metadata must begin with the prefix "x-amz-meta-", otherwise Amazon S3
will not set the key value pair as you define it. You define custom
metadata by adding a name that you choose to the x-amz-meta- key. This
creates a custom key. For example, if you add the custom name
alt-name, the metadata key would be x-amz-meta-alt-name.
参见 User-Defined Object Metadata 的文档：
Each key-value pair must conform to US-ASCII when you are using REST and to UTF-8 when you are using SOAP or browser-based uploads via POST.
我假设您使用的是 REST。
