This article introduces code examples for common object deletion scenarios.
Delete Directory
The following code is used to delete objects in the specified directory exampledir/.
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 dir = 'exampledir/';
let continuationToken = '';
while (true) {
const res = await client.listObjectsType2({
Bucket: bucketName,
MaxKeys: 1000,
ContinuationToken: continuationToken,
Prefix: dir,
});
for (const obj of res.Contents) {
const res2 = await client.deleteObject({
Bucket: bucketName,
Key: obj.Key,
});
console.log('deleteObject %s Request ID:', obj.Key, res2.RequestId);
}
if (!res.IsTruncated) {
break;
}
continuationToken = res.NextContinuationToken ?? '';
}
} catch (error) {
handleError(error);
}
}
main();
Empty Bucket
The following code is used to clear the entire bucket, including deleting all objects and all unmerged objects.
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);
}
}
async function main() {
try {
let continuationToken = '';
while (true) {
const res = await client.listObjectsType2({
Bucket: bucketName,
MaxKeys: 1000,
ContinuationToken: continuationToken,
});
for (const obj of res.Contents) {
const res2 = await client.deleteObject({
Bucket: bucketName,
Key: obj.Key,
});
console.log('deleteObject %s Request ID:', obj.Key, res2.RequestId);
}
if (!res.IsTruncated) {
break;
}
continuationToken = res.NextContinuationToken ?? '';
}
let keyMarker2 = '';
let uploadIdMarker = '';
while (true) {
const res = await client.listMultipartUploads({
Bucket: bucketName,
MaxUploads: 1000,
KeyMarker: keyMarker2,
UploadIdMarker: uploadIdMarker,
});
for (const upload of res.Uploads) {
const res2 = await client.abortMultipartUpload({
Bucket: bucketName,
Key: upload.Key,
UploadID: upload.UploadId,
});
console.log('abortMultipartUpload uploadId: %s, requestId: %s', upload.UploadId, res2.RequestId);
}
if (!res.IsTruncated) {
break;
}
keyMarker2 = res.NextKeyMarker ?? '';
uploadIdMarker = res.NextUploadIdMarker ?? '';
}
} catch (error) {
handleError(error);
}
}
main();
Emptying a versioning-enabled bucket
The following code provides an example for clearing an entire bucket with versioning enabled, including deleting all versions of objects, all versions of delete markers, and all incomplete multipart uploads.
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);
}
}
async function main() {
try {
const bucketName = 'harmonyos-sdk-test-bucket';
let keyMarker = '';
let versionIdMarker = '';
while (true) {
const res = await client.listObjectVersions({
MaxKeys: 1000,
Bucket: bucketName,
KeyMarker: keyMarker,
VersionIDMarker: versionIdMarker,
});
for (const object of res.Versions) {
const res2 = await client.deleteObject({
Bucket: bucketName,
Key: object.Key,
VersionID: object.VersionId,
});
console.log('deleteObject %s Request ID:', object.Key, res2.RequestId);
}
for (const markers of res.DeleteMarkers) {
const res2 = await client.deleteObject({
Bucket: bucketName,
Key: markers.Key,
VersionID: markers.VersionId,
});
console.log('deleteObject DeleteMarker %s Request ID:', markers.Key, res2.RequestId);
}
if (!res.IsTruncated) {
break;
}
keyMarker = res.NextKeyMarker ?? '';
versionIdMarker = res.NextVersionIdMarker ?? '';
}
let keyMarker2 = '';
let uploadIdMarker = '';
while (true) {
const res = await client.listMultipartUploads({
Bucket: bucketName,
MaxUploads: 1000,
KeyMarker: keyMarker2,
UploadIdMarker: uploadIdMarker,
});
for (const upload of res.Uploads) {
const res2 = await client.abortMultipartUpload({
Bucket: bucketName,
Key: upload.Key,
UploadID: upload.UploadId,
});
console.log('abortMultipartUpload uploadId: %s, requestId: %s', upload.UploadId, res2.RequestId);
}
if (!res.IsTruncated) {
break;
}
keyMarker = res.NextKeyMarker ?? '';
uploadIdMarker = res.NextUploadIdMarker ?? '';
}
} catch (error) {
handleError(error);
}
}
main();
