如何使用带有S3和Cloudfront分发的Write-S3Object设置缓存控制？

Question

我一直这样做,但现在它似乎不再起作用(2015年8月):

Write-S3Object -BucketName "example-bucket" 
   -KeyPrefix "app/admin/partials" 
   -Folder 'app/admin/partials' -SearchPattern '*.html' 
   -HeaderCollection @{"Cache-Control" = "public,max-age=120"}

最近发生了什么变化？当我在S3中检查时,没有设置头信息.

您需要在查询中使用-Metadata-HeaderCollection @{"Cache-Control" = "public,max-age=120"}参数，更改参数才能-Metadata @{"Cache-Control" = "public,max-age=120"}正常工作，并且可以在 AWS Web 控制台中看到。

这是工作片段

 Write-S3Object -BucketName myBucket -file "test.json" -Metadata
 @{"Cache-Control" = "public,max-age=120"}

这是使用以下版本的 Powershell 运行的。
