Deleting the Custom Domain Name of a Bucket (SDK for Java)

Function

If encryption is applied to a bucket, objects uploaded to it will be encrypted based on the specified configuration before being stored in OBS. When you download these objects, OBS decrypts them first before returning them to you.

This API deletes the encryption configuration of a bucket.

Restrictions

To use this API, you must be the bucket owner or have the required permission (obs:bucket:PutEncryptionConfiguration in IAM or PutEncryptionConfiguration in a bucket policy).

Method

ObsClient.deleteBucketCustomDomain(DeleteBucketCustomDomainRequest request)

Request Parameters

**Table 1** DeleteBucketCustomDomainRequest
Parameter	Type	Mandatory (Yes/No)	Description
bucketName	str	Yes	Explanation: Bucket name. Restrictions: A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets with the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request. Value range: None Default value: None

Responses

**Table 2** Common response headers
Parameter	Type	Description
statusCode	int	Explanation: HTTP status code. Value range: A status code is a group of digits that can be 2xx (indicating successes) or 4xx or 5xx (indicating errors). It indicates the status of a response. Default value: None
responseHeaders	Map<String, Object>	Explanation: HTTP response header list, composed of tuples. In a tuple, the String key indicates the name of the header, and the Object value indicates the value of the header. Default value: None
