Object Storage Service:Delete object tags

Usage notes

• In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS by using other Alibaba Cloud services in the same region as OSS, use an internal endpoint For more information about the regions and endpoints supported by OSS, see Regions and endpoints.
• In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or STS, see Initialization.
• To delete the tags of an object, you must have the oss:DeleteObjectTagging permission. For more information, see Attach a custom policy to a RAM user.

Delete the tags of an object

If versioning is not enabled for the bucket that stores the object whose tags you want to delete, you can delete the tags of the object based on your requirements. If versioning is enabled for the bucket that stores the object whose tags you want to delete, OSS deletes the tags of the current version of the object by default.

The following code provides an example on how to delete the tags of the exampleobject.txt object in the exampledir directory of the examplebucket bucket:

# -*- coding: utf-8 -*-

import oss2
from oss2.models import Tagging, TaggingRule

# The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in OSS is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. 
auth = oss2.Auth('yourAccessKeyId', 'yourAccessKeySecret')
# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. 
# Specify the name of the bucket. Example: examplebucket. 
bucket = oss2.Bucket(auth, 'yourEndpoint', 'examplebucket')
# Specify the full path of the object. The full path of the object cannot contain the bucket name. Example: exampledir/exampleobject.txt. 
object_name = 'exampledir/exampleobject.txt'

# Delete the tags of the object. 
result = bucket.delete_object_tagging(object_name)
print('http response status: ', result.status)

Delete the tags of a specific version of an object

If versioning is enabled for the bucket that stores the object whose tags you want to delete, you can delete the tags of a specified version of the object by specifying the version ID of the object.

The following code provides an example on how to delete the tags of a specified version of the exampleobject.txt object in the exampledir directory of the examplebucket bucket:

# -*- coding: utf-8 -*-

import oss2
from oss2.models import Tagging

# The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in OSS is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. 
auth = oss2.Auth('yourAccessKeyId', 'yourAccessKeySecret')
# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. 
# Specify the name of the bucket. Example: examplebucket. 
bucket = oss2.Bucket(auth, 'yourEndpoint', 'examplebucket')
# Specify the full path of the object. The full path of the object cannot contain the bucket name. Example: exampledir/exampleobject.txt. 
object_name = 'exampledir/exampleobject.txt'
# Specify the version ID of the object. 
version_id = 'CAEQMxiBgICAof2D0BYiIDJhMGE3N2M1YTI1NDQzOGY5NTkyNTI3MGYyMzJm****'

params = dict()
params['versionId'] = version_id
bucket.delete_object_tagging(object_name, params=params)
