AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.
            Using the GetBucketLocation operation is no longer a best practice. To return
            the Region that a bucket resides in, we recommend that you use the HeadBucket
            operation instead. For backward compatibility, Amazon S3 continues to support the
            GetBucketLocation operation.
            
            Returns the Region the bucket resides in. You set the bucket's Region using the LocationConstraint
            request parameter in a CreateBucket request. For more information, see CreateBucket.
            
            In a bucket's home Region, calls to the GetBucketLocation operation are governed
            by the bucket's policy. In other Regions, the bucket policy doesn't apply, which means
            that cross-account access won't be authorized. However, calls to the HeadBucket
            operation always return the bucket’s location through an HTTP response header, whether
            access to the bucket is authorized or not. Therefore, we recommend using the HeadBucket
            operation for bucket Region discovery and to avoid using the GetBucketLocation
            operation.
            
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.
            
This operation is not supported for directory buckets.
            The following operations are related to GetBucketLocation:
            
            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.
