[Cloud functions] How to get the UserID of the user that is triggering a write in the database

[Joe Roy]

I have a cloud function that triggers on write of a particular location in the database. I'm trying to retrieve the UserID of the user that triggered the write. Is this possible? I'd rather avoid having the user write his user ID inside the message he is writing if possible.
