This interface is used to enumerate the unmerged objects in the bucket, that is, to enumerate the shard upload task.
Precautions
Before listing the shard upload tasks, you need to have the tos: ListBucketMultipartUploadspermission. For details, see Overview.
Parameter description
parameter | describe |
parameter | describe |
delimiter | Characters to group object names. |
encodingType | Encodes the returned content and specifies the type of encoding. The value selection description is as follows:
|
maxUploads | Returns the maximum number of shard upload tasks. The default value is 1000. Value: (0, 1000] |
prefix | Used to specify the prefix name of the enumerated returned object. |
keyMarker | List the starting position of the shard upload task. Sets to return a list of objects sorted alphabetically from the value. Usually the nextMarkervalue returned by the last request. |
uploadIDMarker | Used with keyMarker, set to return a sharded upload task list sorted by dictionary from this value. Gets the nextVersionIdMarkerfrom the last enumeration. |
Sample code
Simple list
The following code enumerates up to 10 unmerged shard upload tasks in the specified bucket.
// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
// Create a client.
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
region: "Provide your region", // Fill in the region where the Bucket is located. For example, if it is in China North 2 (Beijing), fill in "Provide your region" as cn-beijing.
endpoint: "Provide your endpoint", // Enter the domain address.
});
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 {
// Get up to 10 unfinished tasks from the bucket.
const { data } = await client.listMultipartUploads({
bucket: bucketName,
maxKeys: 1000,
});
console.log('Uploads.length:', data.Uploads.length);
for (const upload of data.Uploads) {
console.log('Object Key:', upload.Key);
console.log('UploadID:', upload.UploadId);
console.log('Owner:', upload.Owner);
console.log('StorageClass:', upload.StorageClass);
}
} catch (error) {
handleError(error);
}
}
main();
List all unmerged sharding tasks with the specified prefix
The following code enumerates all unmerged shard upload tasks under the specified bucket prefix.
// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
// Create a client.
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
region: "Provide your region", // Fill in the region where the Bucket is located. For example, if it is in China North 2 (Beijing), fill in "Provide your region" as cn-beijing.
endpoint: "Provide your endpoint", // Enter the domain address.
});
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 {
// List all multi-version objects with the specified prefix.
const prefix = '*** Provide your object key prefix ***';
for (let truncated = true, keyMarker = '', uploadIdMarker = ''; truncated; ) {
const { data } = await client.listMultipartUploads({
bucket: bucketName,
maxUploads: 1000,
prefix,
keyMarker,
uploadIdMarker,
});
console.log('Uploads.length:', data.Uploads.length);
for (const upload of data.Uploads) {
console.log('Object Key:', upload.Key);
console.log('UploadID:', upload.UploadId);
console.log('Owner:', upload.Owner);
console.log('StorageClass:', upload.StorageClass);
}

keyMarker = data.NextKeyMarker;
uploadIdMarker = data.NextUploadIdMarker;
}
} catch (error) {
handleError(error);
}
}
main();
List all shard upload tasks
The following code enumerates all shard upload tasks for which buckets are not merged.
// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';
// Create a client.
const client = new TosClient({
accessKeyId: process.env['TOS_ACCESS_KEY'],
accessKeySecret: process.env['TOS_SECRET_KEY'],
region: "Provide your region", // Fill in the region where the Bucket is located. For example, if it is in China North 2 (Beijing), fill in "Provide your region" as cn-beijing.
endpoint: "Provide your endpoint", // Enter the domain address.
});
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 {
// List all multi-version objects.
for (let truncated = true, keyMarker = '', uploadIdMarker = ''; truncated; ) {
const { data } = await client.listMultipartUploads({
bucket: bucketName,
maxUploads: 1000,
keyMarker,
uploadIdMarker,
});
console.log('Uploads.length:', data.Uploads.length);

}
} catch (error) {
handleError(error);
}
}
