Returns the policy of a specified bucket.
Directory buckets - For directory buckets, you must make requests for this
API operation to the Regional endpoint. These endpoints support path-style requests
in the format https://s3express-control.region-code.amazonaws.com/bucket-name
. Virtual-hosted-style requests aren't supported. For more information about endpoints
in Availability Zones, see Regional
and Zonal endpoints for directory buckets in Availability Zones in the Amazon
S3 User Guide. For more information about endpoints in Local Zones, see Available
Local Zone for directory buckets in the Amazon S3 User Guide.
If you are using an identity other than the root user of the Amazon Web Services account
that owns the bucket, the calling identity must both have the GetBucketPolicy
permissions on the specified bucket and belong to the bucket owner's account in order
to use this operation.
If you don't have GetBucketPolicy
permissions, Amazon S3 returns a 403 Access
Denied
error. If you have the correct permissions, but you're not using an identity
that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not
Allowed
error.
To ensure that bucket owners don't inadvertently lock themselves out of their own
buckets, the root principal in a bucket owner's Amazon Web Services account can perform
the GetBucketPolicy
, PutBucketPolicy
, and DeleteBucketPolicy
API actions, even if their bucket policy explicitly denies the root principal's access.
Bucket owner root principals can only be blocked from performing these API actions
by VPC endpoint policies and Amazon Web Services Organizations policies.
General purpose bucket permissions - The s3:GetBucketPolicy
permission
is required in a policy. For more information about general purpose buckets bucket
policies, see Using
Bucket Policies and User Policies in the Amazon S3 User Guide.
Directory bucket permissions - To grant access to this API operation, you
must have the s3express:GetBucketPolicy
permission in an IAM identity-based
policy instead of a bucket policy. Cross-account access to this API operation isn't
supported. This operation can only be performed by the Amazon Web Services account
that owns the resource. For more information about directory bucket policies and permissions,
see Amazon
Web Services Identity and Access Management (IAM) for S3 Express One Zone in the
Amazon S3 User Guide.
General purpose buckets example bucket policies - See Bucket policy examples in the Amazon S3 User Guide.
Directory bucket example bucket policies - See Example bucket policies for S3 Express One Zone in the Amazon S3 User Guide.
Directory buckets - The HTTP Host header syntax is s3express-control.region-code.amazonaws.com
.

public virtual Task<GetBucketPolicyResponse> GetBucketPolicyAsync( String bucketName, CancellationToken cancellationToken )
The bucket name to get the bucket policy for. Directory buckets - When you use this operation with a directory bucket, you must use path-style requests in the format https://s3express-control.region-code.amazonaws.com/bucket-name. Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must also follow the format bucket-base-name--zone-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User GuideAccess points - When you use this API operation with an access point, provide the alias of the access point in place of the bucket name. Object Lambda access points - When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes. Access points and Object Lambda access points are not supported by directory buckets.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
