Need help implementing ActivityPub - getting inconsistent results across platforms (blenderdumbass.org)

submitted 1 week ago by [email protected] to c/[email protected]

19 comments fedilink hide all child comments

My friend is working on adding ActivityPub support to his blog platform (BDServer) so people can follow/comment from Mastodon, Lemmy, etc.

Current status: Lemmy and Misskey can find and follow his account (@[email protected]), but Mastodon can't find it at all, even though he sees proper ActivityPub requests hitting his server.

The technical details are pretty gnarly - RSA signature verification, HTTP header recreation, multi-threading issues. He wrote up the full journey here: Please Help Me With Activity Pub

If anyone has ActivityPub experience or wants to take a look at the code (Python), we have a Matrix room for BDServer development. Any insights on why different platforms behave differently would be super helpful.

Did something change since this was posted?
I can look it up properly on mastodon.
You have to be signed in to fetch accounts on mastodon, is that the problem?

Are you using any framework to build the site? There's a few libraries for activitypub.

Seems like somebody mentioned the account on the fediverse that started a chain reaction of various instances requesting a bunch of stuff. Which made it to Mastodon.social too. It still doesn't work though.

The server is written in python and the idea is to make it deploy-able without needing to install anything extra. So I'm trying to implement my own activity pub.

For what it's worth your blog does show up fine in NodeBB as well. Perhaps you are missing the @context property and so Mastodon is refusing to parse it?

It's for django, but take a look into my ActivityPub Toolkit. It is designed to be compliant with ActivityPub and not with any particular implementation, so it should be easy for you to adapt to your own needs.

This doesn't have any link to code. And all the other buttons say that the docs are not implemented yet.

The menu has a link to the repository.

Running curl https://blenderdumbass.org/activitypub/account/blenderdumbass -H "Accept: application/activity+json" twice in a row outputs some bunkerweb anti-spam stuff.

[–] [email protected] 2 points 1 week ago (1 children)

Disabled bunker for now.

[–] [email protected] 1 points 1 week ago (1 children)

Also: bunker blocks me 100% of the time on individual articles.

[–] [email protected] 2 points 1 week ago

Should not too I removed all blocks.

[–] [email protected] 2 points 1 week ago (1 children)

try spoofing a user-agent or torifying it maybe

[–] [email protected] 2 points 1 week ago

While I'm sure that would let me see the article, mastodon probably wouldn't handle it well.

I would say for now the most issue is about acually pulling posts.
