[英]How to add new tags to an AWS S3 Bucket using Boto3 if the existing tags on the bucket contains 'aws:' prefixes?
[英]How to add tags to an S3 Bucket without deleting the existing tags using boto3?
我正在使用這個功能:
s3 = boto3.resource('s3')
bucket_tagging = s3.BucketTagging(bucket)
Set_Tag = bucket_tagging.put(Tagging={'TagSet':[{'Key':'Owner', 'Value': owner}]})
它正在刪除現有標簽,我只能看到一個標簽。
我會使用以下
s3 = boto3.resource('s3')
bucket_tagging = s3.BucketTagging('bucket_name')
tags = bucket_tagging.tag_set
tags.append({'Key':'Owner', 'Value': owner})
Set_Tag = bucket_tagging.put(Tagging={'TagSet':tags})
這將獲取現有標簽,添加一個新標簽,然后將它們全部放回原處。
我遇到了同樣的問題並用我自己的方法解決了它:
import boto3
def set_object_keys(bucket, key, update=True, **new_tags):
"""
Add/Update/Overwrite tags to AWS S3 Object
:param bucket_key: Name of the S3 Bucket
:param update: If True: appends new tags else overwrites all tags with **kwargs
:param new_tags: A dictionary of key:value pairs
:return: True if successful
"""
# I prefer to have this var outside of the method. Added for completeness
client = boto3.client('s3')
old_tags = {}
if update:
old = client.get_object_tagging(
Bucket=bucket,
Key=key,
)
old_tags = {i['Key']: i['Value'] for i in old['TagSet']}
new_tags = {**old_tags, **new_tags}
response = client.put_object_tagging(
Bucket=bucket,
Key=key,
Tagging={
'TagSet': [{'Key': str(k), 'Value': str(v)} for k, v in new_tags.items()]
}
)
return response['ResponseMetadata']['HTTPStatusCode'] == 200
然后在函數調用中添加標簽:
set_object_keys(....., name="My Name", colour="purple")
這將添加新標簽並更新現有標簽
import boto3
session = boto3.session.Session(profile_name='default')
client = session.client('s3', 'ap-southeast-2')
def set_bucket_tags(bucket, update=True, **new_tags):
old_tags = {}
if update:
try:
old = client.get_bucket_tagging(Bucket=bucket)
old_tags = {i['Key']: i['Value'] for i in old['TagSet']}
except Exception as e:
print(e)
print("There was no tag")
new_tags = {**old_tags, **new_tags}
response = client.put_bucket_tagging(
Bucket=bucket,
Tagging={
'TagSet': [{'Key': str(k), 'Value': str(v)} for k, v in new_tags.items()]
}
)
print(response)
set_bucket_tags("selim.online", True, key1="value1", key2="value2", key3="value3")
