更改S3存储桶策略中特定文件扩展名的内容类型 [英] Change content-type in S3 bucket policy for a specific file extension

问题描述

当前，当我将属性列表文件(plist扩展名)放入S3存储桶时，由于某种原因，它将Content-type设置为application/octet-stream.当我在Objective-C(iOS)中下载它时会导致问题.

Currently when I place a property list file (plist extension) to a S3 bucket, it sets the Content-type to application/octet-stream for some reason. It causes issues when I download it in Objective-C (iOS).

如何更改存储桶策略，以使其自动将内容类型"设置为文本/纯文本"

How can change the bucket policy so it automatically sets the Content-type to text/plain

推荐答案

您不能.默认的内容类型是"application/octet-stream".

You cannot. The default content-type is "application/octet-stream".

您唯一的选择是在上传时设置内容类型，或者在上传完成后对其进行更新.

The only option you have is setting the content-type at the time of upload or updating it once the upload is complete.
