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-sdk';
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
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 = 'node-sdk-test-bucket';
async function main() {
try {
const dir = 'exampledir/';
for (let truncated = true, continuationToken = ''; truncated; ) {
const { data } = await client.listObjectsType2({
bucket: bucketName,
maxKeys: 1000,
continuationToken: continuationToken,
prefix: dir,
});
for (const obj of data.Contents) {
const { requestId } = await client.deleteObject({
bucket: bucketName,
key: obj.Key,
});
console.log('deleteObject %s Request ID:', obj.Key, requestId);
}
truncated = data.IsTruncated;
continuationToken = data.NextContinuationToken;
}
} catch (error) {
handleError(error);
}
}
main();
Empty Bucket
The following code is used to empty the entire bucket, including deleting all objects and all unmerged objects.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
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 = 'node-sdk-test-bucket';
for (let isTruncated = true, continuationToken = ''; isTruncated; ) {
const { data } = await client.listObjectsType2({
maxKeys: 1000,
bucket: bucketName,
continuationToken,
});
for (const object of data.Contents) {
const { requestId } = await client.deleteObject({
bucket: bucketName,
key: object.Key,
});
console.log('deleteObject %s Request ID:', object.Key, requestId);
}
isTruncated = data.IsTruncated;
continuationToken = data.NextContinuationToken;
}
for (let isTruncated = true, keyMarker = '', uploadIdMarker = ''; isTruncated; ) {
const { data } = await client.listMultipartUploads({
bucket: bucketName,
maxUploads: 1000,
keyMarker,
uploadIdMarker,
});
for (const upload of data.Uploads) {
const { requestId } = await client.abortMultipartUpload({
bucket: bucketName,
key: upload.Key,
uploadId: upload.UploadId,
});
console.log('abortMultipartUpload uploadId: %s, requestId: %s', upload.UploadId, requestId);
}
isTruncated = data.IsTruncated;
keyMarker = data.NextKeyMarker;
uploadIdMarker = data.NextUploadIdMarker;
}
} catch (error) {
handleError(error);
}
}
main();
Emptying a versioned bucket
The following is example code for clearing an entire multi-version enabled bucket, including deleting all versions of objects, deleting all versions of delete markers, and deleting all unmerged objects.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
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 = 'node-sdk-test-bucket';
for (let isTruncated = true, keyMarker = '', versionIdMarker = ''; isTruncated; ) {
const { data } = await client.listObjectVersions({
maxKeys: 1000,
bucket: bucketName,
keyMarker,
versionIdMarker,
});
for (const object of data.Versions) {
const { requestId } = await client.deleteObject({
bucket: bucketName,
key: object.Key,
versionId: object.VersionId,
});
console.log('deleteObject %s Request ID:', object.Key, requestId);
}
for (const markers of data.DeleteMarkers) {
const { requestId } = await client.deleteObject({
bucket: bucketName,
key: markers.Key,
versionId: markers.VersionId,
});
console.log('deleteObject DeleteMarker %s Request ID:', markers.Key, requestId);
}
isTruncated = data.IsTruncated;
keyMarker = data.NextKeyMarker;
versionIdMarker = data.NextVersionIdMarker;
}
for (let isTruncated = true, keyMarker = '', uploadIdMarker = ''; isTruncated; ) {
const { data } = await client.listMultipartUploads({
bucket: bucketName,
maxUploads: 1000,
keyMarker,
uploadIdMarker,
});
for (const upload of data.Uploads) {
const { requestId } = await client.abortMultipartUpload({
bucket: bucketName,
key: upload.Key,
uploadId: upload.UploadId,
});
console.log('abortMultipartUpload uploadId: %s, requestId: %s', upload.UploadId, requestId);
}
isTruncated = data.IsTruncated;
keyMarker = data.NextKeyMarker;
uploadIdMarker = data.NextUploadIdMarker;
}
} catch (error) {
handleError(error);
}
}
main();
