问题
Just checking to see if anyone knows if this is possible yet. I would like to use a wildcard subdomain with firebase hosting and use functions to parse the subdomain.
回答1:
No, Firebase Hosting does not presently support wildcard subdomains. It's something that we'd like to do in the future, but there are no timelines or concrete plans to share at this time.
