swift - 上传到Amazon S3时如何设置权限？

Question

我想将我上传到 S3 的文件设置为所有用户“读取”的权限，但找不到使用 AWSS3PutObjectRequest grantRead 的方法 AWSS3Permission AWSS3PermissionRead。

有什么建议可以解决这个问题吗？

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，文件被上传，但所有用户的权限设置为“无”。我认为问题出在上面代码的倒数第二行。当该行未注释掉时，我收到此错误:

上传()失败:[错误域=com.amazonaws.AWSS3ErrorDomain代码=0“操作无法完成。(com.amazonaws.AWSS3ErrorDomain错误0。)”UserInfo=0x191a5bc0 {HostId=xxx +xxxxxxx/14=, ArgumentValue=所有用户, Message=参数格式无法识别, 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像:

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)
