get_bucket_cors ¶

get_bucket_cors(
    bucket: BucketName,
    *,
    config_overrides: Optional[S3ClientConfig] = None,
    expected_bucket_owner: Optional[AccountId] = None,
) -> GetBucketCorsOutput

This operation is not supported for directory buckets.

Returns the Cross-Origin Resource Sharing (CORS) configuration information set for the bucket.

To use this operation, you must have permission to perform the s3:GetBucketCORS action. By default, the bucket owner has this permission and can grant it to others.

When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.

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.

For more information about CORS, see Enabling Cross-Origin Resource Sharing.

The following operations are related to GetBucketCors:

You must URL encode any signed header values that contain spaces. For example, if your header value is my file.txt, containing two spaces after my, you must URL encode this value to my%20%20file.txt.

Parameters:

bucket (BucketName) –

The bucket name for which to get the cors configuration.

When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.

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.
expected_bucket_owner (Optional[AccountId], default: None ) –

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Raises:

UnknownServiceError –

The service returned an error code this client does not model.

Examples:

To get cors configuration set on a bucket The following example returns cross-origin resource sharing (CORS) configuration set on a bucket.

>>> client.get_bucket_cors(bucket='examplebucket')
