Function

This API is used to add tags to, update tags of, or delete tags from an image in a batch.

Constraints

Each tag consists of a key and a value. The key contains at most 36 characters, and the value contains at most 43 characters. The key cannot be left blank or an empty character string. The value cannot be left blank but can be an empty character string.
An image can have a maximum of 10 tags.
The keys of multiple tags in the request body must be unique.
This API is an idempotent one.
If a tag to be added has the same key as an existing tag, but the tag values are different, this tag will be added and overwrite the existing one. If a tag to be added has the same key and value as an existing tag, this tag will not be added.

If the specified tag does not exist, the deletion is considered successful by default.

The rules for key and value verification during batch tag deletion are as follows:
The system does not check characters of keys and values. A key cannot be left blank or be an empty string. Values are optional for keys. If a tag to be deleted does not exist, the system considers that it has been deleted. No error will be reported. The system will check key and value lengths. A key can contain a maximum of 127 characters, and a value can contain a maximum of 255 characters.
