Different undocumented blog identifier format #126

Open mdashlw opened 5 months ago

mdashlw commented 5 months ago

Blog https://www.tumblr.com/rarijackdaily has name of rarijackdaily, uuid of t:r41U3WbkgPsyci1uQtKqfw, and a different identifier of z-9h8LWr1Kv4VZVwZ_KZkw await tumblr.apiFetch('/v2/blog/(blogIdentifier)/posts/114205831908/permalink') supports all three. However, I could not find any information on the format of z-9h8LWr1Kv4VZVwZ_KZkw. I found it on https://rarijackdaily.tumblr.com/post/114205831908/spring-3/embed

Ooh, neat! I'd heard whispers of another blog identifier but my understanding is that it's intentionally not documented or used when possible (probably for reasons like "doesn't stay the same if you change your blog name," if I had to guess).

Yes, there is a third unique public blog identifier, which is still around for some legacy purposes. It's not as reliable or used as widely as the proper blog UUID (the one prefixed with t:), so we don't document it, because we don't recommend relying on it.

I see. Also, what is the format of blog uuids? As far as I can tell, it's not a real uuid

well, it's a "real" UUID in the sense that it's universally unique on Tumblr. it's not a UUID by any of the other standard variants, no. we opted to do something much shorter than the typical UUID v4, for example, because we just didn't need it to be that big.
