Object Storage Service:Delete a bucket

Prerequisites

• All objects in the bucket are deleted.
  • For more information about how to manually delete objects, see Delete objects.
  • To delete a large number of objects, we recommend that you configure lifecycle rules to batch delete the objects. For more information, see Configure lifecycle rules.
  Important

  If versioning is enabled for the bucket that you want to delete, make sure that all versions of objects in the bucket are deleted. For more information about how to delete all versions of objects in a bucket, see Configure versioning.

• Parts that are uploaded by multipart upload or resumable upload tasks in the bucket are deleted. For more information about how to delete parts in a bucket, see Manage parts.
• All LiveChannels in the bucket are deleted. For more information about how to delete LiveChannels, see DeleteLiveChannel.

Usage notes

• In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS by using other Alibaba Cloud services in the same region as OSS, use an internal endpoint For more information about the regions and endpoints supported by OSS, see Regions and endpoints.
• In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or STS, see Create an OSSClient instance.
• The oss:DeleteBucket permission is required to delete a bucket. For more information, see Attach a custom policy to a RAM user.

Sample code

The following sample code provides an example on how to delete a bucket named examplebucket:

import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;

public class Demo {

    public static void main(String[] args) throws Exception {
        // In this example, the endpoint of the China (Hangzhou) region is used. Specify your actual endpoint. 
        String endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
        // The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in OSS is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. 
        String accessKeyId = "yourAccessKeyId";
        String accessKeySecret = "yourAccessKeySecret";
        // Specify the name of the bucket. Example: examplebucket. 
        String bucketName = "examplebucket";

        // Create an OSSClient instance. 
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

        try {
            // Delete the bucket. 
            ossClient.deleteBucket(bucketName);
        } catch (OSSException oe) {
            System.out.println("Caught an OSSException, which means your request made it to OSS, "
                    + "but was rejected with an error response for some reason.");
            System.out.println("Error Message:" + oe.getErrorMessage());
            System.out.println("Error Code:" + oe.getErrorCode());
            System.out.println("Request ID:" + oe.getRequestId());
            System.out.println("Host ID:" + oe.getHostId());
        } catch (ClientException ce) {
            System.out.println("Caught an ClientException, which means the client encountered "
                    + "a serious internal problem while trying to communicate with OSS, "
                    + "such as not being able to access the network.");
            System.out.println("Error Message:" + ce.getMessage());
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }
    }
}
