TOS supports the renaming of individual objects within a bucket. To use the object renaming feature, you must first enable the bucket's renaming function.
Enable bucket renaming rules
You can enable the bucket renaming feature through the PutBucketRename interface of the TOS Java SDK.
Category
- The renameEnable parameter can only be set to true.
- Enabling the rename function is not supported for multi-version buckets.
Sample Code
The following code demonstrates how to enable the bucket renaming feature.
import com.volcengine.tos.TOSV2;
import com.volcengine.tos.TOSV2ClientBuilder;
import com.volcengine.tos.TosClientException;
import com.volcengine.tos.TosServerException;
import com.volcengine.tos.model.bucket.PutBucketRenameInput;
import com.volcengine.tos.model.bucket.PutBucketRenameOutput;
public class PutBucketRenameExample {
public static void main(String[] args) {
String endpoint = "your endpoint";
String region = "your region";
String accessKey = System.getenv("TOS_ACCESS_KEY");
String secretKey = System.getenv("TOS_SECRET_KEY");
String bucketName = "bucket-example";
TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);
try{
boolean renameEnable = true;
PutBucketRenameInput input = new PutBucketRenameInput().setBucket(bucketName).setRenameEnable(renameEnable);
PutBucketRenameOutput output = tos.putBucketRename(input);
System.out.println("putBucketRename succeed");
} catch (TosClientException e) {
System.out.println("putBucketRename failed");
System.out.println("Message: " + e.getMessage());
if (e.getCause() != null) {
e.getCause().printStackTrace();
}
} catch (TosServerException e) {
System.out.println("putBucketRename failed");
System.out.println("StatusCode: " + e.getStatusCode());
System.out.println("Code: " + e.getCode());
System.out.println("Message: " + e.getMessage());
System.out.println("RequestID: " + e.getRequestID());
} catch (Throwable t) {
System.out.println("putBucketRename failed");
System.out.println("unexpected exception, message: " + t.getMessage());
}
}
}
Retrieve the bucket renaming rules.
You can query whether a bucket is in the rename enabled state via the TOS Java SDK GetBucketRename API.
Category
Get whether the bucket is in the renaming enabled state; by default, you must be the bucket owner.
Sample Code
The following code demonstrates how to query the renaming status of a bucket.
import com.volcengine.tos.TOSV2;
import com.volcengine.tos.TOSV2ClientBuilder;
import com.volcengine.tos.TosClientException;
import com.volcengine.tos.TosServerException;
import com.volcengine.tos.model.bucket.GetBucketRenameInput;
import com.volcengine.tos.model.bucket.GetBucketRenameOutput;
public class GetBucketRenameExample {
public static void main(String[] args) {
String endpoint = "your endpoint";
String region = "your region";
String accessKey = System.getenv("TOS_ACCESS_KEY");
String secretKey = System.getenv("TOS_SECRET_KEY");
String bucketName = "bucket-example";
TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);
try{
GetBucketRenameInput input = new GetBucketRenameInput().setBucket(bucketName);
GetBucketRenameOutput output = tos.getBucketRename(input);
System.out.println("getBucketRename succeed, bucket rename enable? " + output.isRenameEnable());
} catch (TosClientException e) {
System.out.println("getBucketRename failed");
System.out.println("Message: " + e.getMessage());
if (e.getCause() != null) {
e.getCause().printStackTrace();
}
} catch (TosServerException e) {
System.out.println("getBucketRename failed");
System.out.println("StatusCode: " + e.getStatusCode());
System.out.println("Code: " + e.getCode());
System.out.println("Message: " + e.getMessage());
System.out.println("RequestID: " + e.getRequestID());
} catch (Throwable t) {
System.out.println("getBucketPolicy failed");
System.out.println("unexpected exception, message: " + t.getMessage());
}
}
}
Disable bucket renaming rules
You can disable the bucket rename status via the TOS Java SDK DeleteBucketRename interface. Once disabled, renaming operations cannot be performed.
Category
To disable the renaming status of a bucket, you must be the bucket owner by default.
Sample Code
The following code demonstrates how to disable the renaming state of a bucket.
import com.volcengine.tos.TOSV2;
import com.volcengine.tos.TOSV2ClientBuilder;
import com.volcengine.tos.TosClientException;
import com.volcengine.tos.TosServerException;
import com.volcengine.tos.model.bucket.DeleteBucketRenameInput;
import com.volcengine.tos.model.bucket.DeleteBucketRenameOutput;
public class DeleteBucketRenameExample {
public static void main(String[] args) {
String endpoint = "your endpoint";
String region = "your region";
String accessKey = System.getenv("TOS_ACCESS_KEY");
String secretKey = System.getenv("TOS_SECRET_KEY");
String bucketName = "bucket-example";
TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);
try{
DeleteBucketRenameInput input = new DeleteBucketRenameInput().setBucket(bucketName);
DeleteBucketRenameOutput output = tos.deleteBucketRename(input);
System.out.println("deleteBucketRename succeed, " + output);
} catch (TosClientException e) {
System.out.println("deleteBucketRename failed");
System.out.println("Message: " + e.getMessage());
if (e.getCause() != null) {
e.getCause().printStackTrace();
}
} catch (TosServerException e) {
System.out.println("deleteBucketRename failed");
System.out.println("StatusCode: " + e.getStatusCode());
System.out.println("Code: " + e.getCode());
System.out.println("Message: " + e.getMessage());
System.out.println("RequestID: " + e.getRequestID());
} catch (Throwable t) {
System.out.println("deleteBucketPolicy failed");
System.out.println("unexpected exception, message: " + t.getMessage());
}
}
}
