Obtaining Storage Information About a Bucket

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

The storage information about a bucket includes the used capacity of and the number of objects in the bucket.

You can call ObsClient.getBucketStorageInfo to obtain the bucket storage information.

This example returns the storage information of bucket bucketname.

The example code is as follows:

// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
String endPoint = "https://your-endpoint";
// Create an instance of ObsClient.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

BucketStorageInfo storageInfo = obsClient.getBucketStorageInfo("bucketname");
Log.i("GetBucketStorageInfo", "\t" + storageInfo.getObjectNumber());
Log.i("GetBucketStorageInfo", "\t" + storageInfo.getSize());
