Multiple handles for Activity Intents
-
Hi @benpate@mastodon.social I've got a question about Activity Intents!
I'm implementing it now (as you noticed) and have run into an interesting issue. The wording of 3b86 suggests that the intents are distinct between users. That is, the end user inputs their handle, the handle is queried via webfinger, and supported Intents are returned.
However, the intents themselves don't really distinguish between users.
So I could have a
localStoragesession with multiple handles registered (e.g.julian@activitypub.space,nodebb@fosstodon.org), etc. β this works fine.But if I had two handles with the same domain,
alice@example.socialandbob@example.social, then my intents can't be targeted, can they... I just fire off the request (or rather, I have the end user's browser navigate) to the intent URL and whatever account is logged in will be the actor.Did I miss something, or was there a way to distinguish actors in Activity Intents?
P.S. I find it highly amusing that you had to click through to activitypub.space to read my whole post, but because I don't support Activity Intents yet, you can't reply properly <img class="not-responsive emoji" src="https://activitypub.space/assets/plugins/nodebb-plugin-emoji/emoji/android/1f923.png?v=8bcefe1b72a" title="

That makes sense. Iβve been building out contexts for conversations, so itβs top of mind for me. But it makes sense that audience and inReplyTo might be enough. If the context is missing, Iβd probably just fill in the context from the parent anyway.

@julian I can do that. Both terms *are* in the Activity Vocabulary, so we're well within the spec to include them here. But yeah, it would be good to include a note that points to the FEPs where they're really defined.
Ok. More to do...

@julian You can certainly use the intent buttons on Bandwagon and the Qwertylicious demo site. They're actually two different implementations, so it might be valid to try both of them.
I'm pretty sure that @pfefferle has implemented some buttons in the WordPress plugin - Matthias, do you have a demo site we can test with?
And, I know Mastodon's Activity Intent work has landed, but I'm not familiar enough with their buttons to say which is being powered by Activity Intents, or how.
