How can I get the username of the current commit through the API?

Problem to solve

This username is not a setting in git config
So this commit API does not meet the requirements
commits_resault
I don't want this. instead of username in git

Further details

Previously we used commit statuses API to get the real username, but sometimes this interface can't get the data (the return content is [])

The normal return value should look like this: commits_statuses_resault
