在 AWS S3 存储桶中获取文件的标签

Question

I have a bucket in AWS S3. Lets call it MY_BUCKET.

I would like to iterate the files in this bucket (with Python) and get the tags keys and values.

How do I do it?

Answer 1

Code to get tags :

s3_resource = boto3.resource('s3')
client = boto3.client('s3')
bucket = s3_resource.Bucket("MY_BUCKET")

for name in bucket.objects.all() :
    response = client.get_object_tagging (
        Bucket = bucket.name,
        Key = name.key
)
print(name.key, response["TagSet"], sep = "\t")

First, it retrieves all objects of the bucket using bucket.objects.all() and for each object, call get_object_tagging which returns dictionary which contains Tagset of the object.

Thanks, Hope it helps !!

Answer 2

Your code would:

• Use list_objects_v2() to obtain a list of the objects in the bucket
• For each object, call head_object() , which returns metadata
• Parse metadata for the tags

The above functions use the client method of calling S3. You could probably do it with the resource method too if that is your preference.
