推荐答案

要上传，您可以使用 #withCannedAcl 方法之前使文件公开> PutObjectRequest ：

To make the file public before uploading you can use the #withCannedAcl method of PutObjectRequest:

myAmazonS3Client.putObject(new PutObjectRequest('some-grails-bucket',  'somePath/someKey.jpg', new    File('/Users/ben/Desktop/photo.jpg')).withCannedAcl(CannedAccessControlList.PublicRead))
