Applies an Amazon S3 bucket policy to an Amazon S3 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 PutBucketPolicy
permissions on the specified bucket and belong to the bucket owner's account in order
to use this operation.
If you don't have PutBucketPolicy 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:PutBucketPolicy 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:PutBucketPolicy 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.

public abstract PutBucketPolicyResponse PutBucketPolicy( String bucketName, String policy )
The name of the bucket. 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 Guide
The bucket policy as a JSON document. For directory buckets, the only IAM action supported in the bucket policy is s3express:CreateSession.
