Prerequisites

Before you begin, make sure that you have:

• Installed the ali-oss package (npm install ali-oss)

• Set the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables

Delete object tags

Method signature

client.deleteObjectTagging(objectName[, options]) → result

Example

const OSS = require('ali-oss');

const client = new OSS({
  // Set region to the region where the bucket is located.
  // For example, if the bucket is in the China (Hangzhou) region, set region to oss-cn-hangzhou.
  region: '<your-region>',
  // Load credentials from environment variables.
  accessKeyId: process.env.OSS_ACCESS_KEY_ID,
  accessKeySecret: process.env.OSS_ACCESS_KEY_SECRET,
  authorizationV4: true,
  bucket: 'examplebucket',
});

async function deleteObjectTagging(objectName) {
  try {
    const result = await client.deleteObjectTagging(objectName);
    console.log(result);
  } catch (e) {
    console.log(e);
  }
}

// Specify the full path of the object, excluding the bucket name.
// For example: exampledir/exampleobject.txt
deleteObjectTagging('exampledir/exampleobject.txt');

Delete tags from a specific version of an object

When versioning is enabled, pass the version ID to target a specific version.

// Reuse the client initialized above.

async function deleteObjectTaggingByVersion(objectName, versionId) {
  try {
    const result = await client.deleteObjectTagging(objectName, { versionId });
    console.log(result);
  } catch (e) {
    console.log(e);
  }
}

deleteObjectTaggingByVersion(
  'exampledir/exampleobject.txt',
  'CAEQIRiBgMDqvPqA3BciIDJhMjE4MWZkN2ViYTRmYzJhZjkxMzk2YWM2NjJk****'
);
