Obtaining a Bucket Storage Quota (SDK for Java)

Function

This API returns the storage quota (upper limit of the storage capacity) of a bucket. If the quota is 0, there is no upper limit on the bucket capacity.

Restrictions

A bucket quota must be a non-negative integer in bytes.
A frozen bucket owner (due to account in arrears) is not allowed to query the bucket storage quota.
To obtain the storage quota of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketQuota in IAM or GetBucketQuota in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.

Method

obsClient.getBucketQuota(String bucketName)

Request Parameters

**Table 1** List of request parameters
Parameter	Type	Mandatory (Yes/No)	Description
bucketName	String	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 of 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. Default value: None

Responses

**Table 2** BucketQuota
Parameter	Type	Mandatory (Yes/No)	Description
bucketQuota	long	Yes	Explanation: Bucket quota. Value range: A non-negative integer, in bytes. Default value: 0, indicating that there is no limit on the bucket quota.

Code Examples

This example returns the quota of bucket exampleBucket.
