Obtaining Bucket Metadata

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 .

You can call ObsClient.getBucketMetadata to obtain the metadata of a bucket. Sample 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/eu/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);

BucketMetadataInfoRequest request = new BucketMetadataInfoRequest("bucketname");
request.setOrigin("http://www.a.com");
//Obtain bucket metadata.
BucketMetadataInfoResult result = obsClient.getBucketMetadata(request);
Log.i("GetBucketMetadata", "\t:" + result.getDefaultStorageClass());
Log.i("GetBucketMetadata", "\t:" + result.getAllowOrigin());
Log.i("GetBucketMetadata", "\t:" + result.getMaxAge());
Log.i("GetBucketMetadata", "\t:" + result.getAllowHeaders());
Log.i("GetBucketMetadata", "\t:" + result.getAllowMethods());
Log.i("GetBucketMetadata", "\t:" + result.getExposeHeaders());

For details about values of methods, such as BucketMetadataInfoResult.getAllowMethods, see the CORS configurations of the bucket.
