如何在上传到Amazon S3时设置权限？

Question

我想为我上传到S3的文件设置权限＆＃34;阅读＆＃34;对于所有用户，但找不到使用AWSS3PutObjectRequest grantRead AWSS3Permission AWSS3PermissionRead的方法。

有任何建议如何解决问题？

这是我的代码：

let uploadRequest = AWSS3TransferManagerUploadRequest()
uploadRequest.body = NSURL(fileURLWithPath: filePath)
uploadRequest.key = fileName
uploadRequest.bucket = S3BucketName
uploadRequest.grantFullControl = "All users" // I think here's an error
self.upload(uploadRequest)

当我注释掉uploadRequest.grantFullControl = "All users"行时，文件会被上传，但所有用户的权限都设置为无。我认为问题出在上面代码的倒数第二行。如果没有注释掉该行，我会收到此错误：

upload（）失败：[错误域= com.amazonaws.AWSS3ErrorDomain代码= 0＆＃34;操作无法完成。 （com.amazonaws.AWSS3ErrorDomain错误0。）＆＃34; UserInfo = 0x191a5bc0 {HostId = xxx + xxxxxxx / 14 =，ArgumentValue =所有用户，消息=无法识别参数格式，ArgumentName = x-amz-grant-full-control，Code = InvalidArgument，RequestId = xxxx}]

编辑：上面的代码实际上尝试授予完全控制权限，但核心问题是相同的。我还添加了一张显示上传文件权限的图片：

我找到了解决方案：

let uploadRequest = AWSS3TransferManagerUploadRequest()
uploadRequest.body = NSURL(fileURLWithPath: filePath)
uploadRequest.key = fileName
uploadRequest.bucket = S3BucketName
uploadRequest.ACL = AWSS3ObjectCannedACL.PublicRead  // there was the error
self.upload(uploadRequest)
