A bucket is a container used to store objects in Object Storage Service (OSS). This topic describes how to query information about a bucket.

Sample code

The following code provides an example on how to query the information about a bucket:

GetBucketInfoRequest request = new GetBucketInfoRequest("bucketName");

// Query the information about the bucket. 
OSSAsyncTask task = oss.asyncGetBucketInfo(request, new OSSCompletedCallback<GetBucketInfoRequest, GetBucketInfoResult>() {
    public void onSuccess(GetBucketInfoRequest request, GetBucketInfoResult result) {
        OSSLog.logInfo("code: " + result.getStatusCode());

    public void onFailure(GetBucketInfoRequest request, ClientException clientException, ServiceException serviceException) {
        // Handle request exceptions. 
        if (clientException != null) {
            // Handle client exceptions, such as network exceptions. 
        if (serviceException != null) {
            // Handle service exceptions. 
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
