If you need to rename a file within a Bucket, you can use the CopyObject interface to copy the source object to the target object, and then use the DeleteObject interface to delete the source object.
Renaming an Individual Object
The following code is used to rename the object src-object in the bucket to dest-object.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos_harmonyos_sdk';
const client = new TosClient({
accessKeyId: "Provide your ak",
accessKeySecret: "Provide your sk",
securityToken: 'Provide your securityToken',
region: "Provide your region",
endpoint: "Provide your endpoint",
});
function handleError(error) {
if (error instanceof TosClientError) {
console.log('Client Err Msg:', error.message);
console.log('Client Err Stack:', error.stack);
} else if (error instanceof TosServerError) {
console.log('Request ID:', error.requestId);
console.log('Response Status Code:', error.statusCode);
console.log('Response Header:', error.headers);
console.log('Response Err Code:', error.code);
console.log('Response Err Msg:', error.message);
} else {
console.log('unexpected exception, message: ', error);
}
}
const bucketName = 'harmonyos-sdk-test-bucket';
async function main() {
try {
const srcObjectKey = 'src-object';
const dstObjectKey = 'dest-object';
const res = await client.copyObject({
Bucket: bucketName,
Key: dstObjectKey,
SrcBucket: bucketName,
SrcKey: srcObjectKey,
});
console.log('copyObject Request ID:', res.RequestId);
const res2 = await client.deleteObject({
Bucket: bucketName,
Key: srcObjectKey,
});
console.log('deleteObject Request ID:', res2.RequestId);
} catch (error) {
handleError(error);
}
}
main();
Rename Directory
The following code is used to rename the directory exampledir1/ to exampledir2/ within the specified storage bucket.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos_harmonyos_sdk';
const client = new TosClient({
accessKeyId: "Provide your ak",
accessKeySecret: "Provide your sk",
securityToken: 'Provide your securityToken',
region: "Provide your region",
endpoint: "Provide your endpoint",
});
async function main() {
try {
const srcDir = 'exampledir1/';
const dstDir = 'exampledir2/';
let continuationToken = '';
while (true) {
const res = await client.listObjectsType2({
Bucket: bucketName,
MaxKeys: 1000,
ContinuationToken: continuationToken,
Prefix: srcDir,
});
for (const obj of res.Contents) {
const res2 = await client.copyObject({
Bucket: bucketName,
Key: obj.Key.replace(srcDir, dstDir),
SrcBucket: bucketName,
SrcKey: obj.Key,
});
console.log('copyObject %s Request ID:', obj.Key, res2.RequestId);
const res3 = await client.deleteObject({
Bucket: bucketName,
Key: obj.Key,
});
console.log('deleteObject %s Request ID:', obj.Key, res3.RequestId);
}
if (!res.IsTruncated) {
break;
}
continuationToken = res.NextContinuationToken ?? '';
}
} catch (error) {
handleError(error);
}
}
main();
