This document describes how to rename objects using the TOS Java SDK.
Category
- Starting from version 2.6.0, the TOS Java SDK supports object renaming.
- Before using the renaming function, you must first enable the renaming function.
- RenameObject only supports renaming objects uploaded after it is enabled. Objects uploaded before this feature is enabled are not supported.
- Concurrent renaming is not supported for the same object.
- All information contained in the metadata of the renamed object is identical to that of the source object.
- Only single-object renaming is supported; batch renaming is not available.
- Multi-version objects do not support renaming.
- A 400 error will occur if the objectKey remains the same during renaming; for example, renaming objectA to objectA.
- If the objectKey to be renamed already exists, it will be overwritten by default. For example, if there are two objects, objectA and objectB, and objectA is renamed to objectB, the data of objectB will be overwritten. For more information, see Using RenameObject.
Sample Code
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.object.RenameObjectInput;
import com.volcengine.tos.model.object.RenameObjectOutput;
public class RenameObjectExample {
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";
String objectKey = "example_dir/example_object.txt";
String renamedObjectKey = "example_dir/example_object_rename.txt";
TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);
try{
RenameObjectInput input = new RenameObjectInput().setBucket(bucketName).setKey(objectKey)
.setNewKey(renamedObjectKey);
RenameObjectOutput output = tos.renameObject(input);
System.out.println(output.getRequestInfo().getRequestId());
System.out.println("renameObject succeed.");
} catch (TosClientException e) {
System.out.println("renameObject failed");
System.out.println("Message: " + e.getMessage());
if (e.getCause() != null) {
e.getCause().printStackTrace();
}
} catch (TosServerException e) {
System.out.println("renameObject failed");
System.out.println("StatusCode: " + e.getStatusCode());
System.out.println("RequestID: " + e.getRequestID());
} catch (Throwable t) {
System.out.println("renameObject failed");
System.out.println("unexpected exception, message: " + t.getMessage());
}
}
}
