When an object is no longer in use, you can delete it to reduce costs. Currently, the TOS Harmony SDK supports deleting individual objects and multiple specified objects within a bucket. For buckets with versioning enabled, you can specify and delete any version data of an object.
Precautions
- Before deleting an object, you must have the tos:DeleteObject permission. For specific instructions, refer to the Permission Configuration Guide.
- For buckets with versioning enabled, you must have the tos:DeleteObjectVersion permission before deleting a specified version of an object. For detailed instructions, please refer to the Permission Configuration Guide.
Sample Code
Delete Specified 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 Name:', error.name);
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 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 = 'harmony-sdk-test-bucket';
const objectKey = '*** Provide your object key ***';
const res = await client.deleteObject({
Bucket: bucketName,
Key: objectKey,
});
console.log('deleteObject Request ID:', res.RequestId);
} catch (error) {
handleError(error);
}
}
main();
Delete the Specified Version of the 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 Name:', error.name);
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 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 = 'harmony-sdk-test-bucket';
const objectKey = '*** Provide your object key ***';
const versionId = `*** Provide objectKey's version id ***`;
const res = await client.deleteObject({
Bucket: bucketName,
Key: objectKey,
VersionID: versionId
});
console.log('deleteObject Request ID:', res.RequestId);
} catch (error) {
handleError(error);
}
}
main();
Batch Deletion of Specified Objects
warning
In a bucket with versioning enabled, when the DeleteMultiObjects API is called to delete objects in bulk, if the versionId is not specified in the Delete request, a delete marker will be inserted. If versionId is specified, the designated version of the object will be permanently deleted.
The response mode supported by batch object deletion can be configured via quiet:
- When quiet is set to false, the response will include the deletion result regardless of whether the object was successfully deleted.
- When quiet is set to true, only the results of objects that failed to be deleted are returned in the response; objects not included in the response are considered successfully deleted.
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) {

console.log('Client Err Name:', error.name);
console.log('Client Err Msg:', error.message);
console.log('Client Err Stack:', error.stack);

console.log('Response Status Code:', error.statusCode);
console.log('Response Header:', error.headers);

} else {

}
}
async function main() {
try {
const bucketName = 'node-sdk-test-bucket';
const objectKey1 = '*** Provide your object key ***';
const objectKey2 = '*** Provide your object key ***';
const res = await client.deleteMultiObjects({
Bucket: bucketName,
Objects: [new ObjectTobeDeleted(objectKey1), new ObjectTobeDeleted(objectKey2)],
