Properties

NameTypeDescription
Public Property AccessControlList Amazon.S3.Model.S3AccessControlList

Custom ACLs to be applied to the bucket or object.

Public Property BucketName System.String

The bucket name that contains the object to which you want to attach the ACL.

When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this operation with an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide.

Public Property CannedACL Amazon.S3.S3CannedACL

The canned ACL to apply to the bucket.

Public Property ExpectedBucketOwner System.String

The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

Public Property Key System.String

The key of an S3 object. If not specified, the ACLs are applied to the bucket.

When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this operation with an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide.

When using this API with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When using this operation using S3 on Outposts through the AWS SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using S3 on Outposts in the Amazon Simple Storage Service Developer Guide.

Public Property VersionId System.String

If set and an object key has been specified, the ACLs are applied to the specific version of the object. This property is ignored if the ACL is to be set on a Bucket.

Examples

This example shows how to set a canned ACL on an object, first to PublicRead, then back to Private.

PutACL sample 1


// Create a client
AmazonS3Client client = new AmazonS3Client();

// Set Canned ACL (PublicRead) for an existing item
client.PutACL(new PutACLRequest
{
    BucketName = "SampleBucket",
    Key = "Item1",
    CannedACL = S3CannedACL.PublicRead
});

// Set Canned ACL (PublicRead) for an existing item
// (This reverts ACL back to default for object)
client.PutACL(new PutACLRequest
{
    BucketName = "SampleBucket",
    Key = "Item1",
    CannedACL = S3CannedACL.Private
});

                

This example shows how to get and set ACLs on an object.

GetACL\PutACL samples


// Create a client
AmazonS3Client client = new AmazonS3Client();

// Retrieve ACL for object
S3AccessControlList acl = client.GetACL(new GetACLRequest
{
    BucketName = "SampleBucket",
    Key = "Item1",
}).AccessControlList;

// Retrieve owner
Owner owner = acl.Owner;


// Describe grant
S3Grant grant = new S3Grant
{
    Grantee = new S3Grantee { EmailAddress = "sample@example.com" },
    Permission = S3Permission.WRITE_ACP
};

// Create new ACL
S3AccessControlList newAcl = new S3AccessControlList
{
    Grants = new List<S3Grant> { grant },
    Owner = owner
};

// Set new ACL
PutACLResponse response = client.PutACL(new PutACLRequest
{
    BucketName = "SampleBucket",
    Key = "Item1",
    AccessControlList = acl
});
