[ActivityPub](https://www.w3.org/TR/activitypub/) is the backbone
|
||||
of the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).
|
||||
Implementing this protocol will allow one to interact with users on
|
||||
[Mastodon](https://joinmastodon.org/),
|
||||
[Pixelfed](https://pixelfed.org/),
|
||||
[Friendica](https://friendi.ca/),
|
||||
and [others](http://fediverse.party/).
|
||||
Unfortuately for a static website, this protocol uses a
|
||||
publish-subscribe pattern. A service would need to be written
|
||||
in order to handle subscribers, pushing messages of published items,
|
||||
as well as receiving mentions.
|
||||
At the current state of my website, I am uninterested in creating
|
||||
such a service. However, I do wish to document the parts
|
||||
of the ActivityPub protocol I was able to implement so far
|
||||
using only a static website.
|
||||
This post extends off of
|
||||
[Eugen Rochko's work](https://blog.joinmastodon.org/2018/06/how-to-implement-a-basic-activitypub-server/)
|
||||
which I encourage you to check out.
|
||||
|
||||
## Webfinger
|
||||
|
||||
When someone looks up a handle on Mastodon, it performs a Webfinger
|
||||
lookup. For example if I am looking up the user `brozek@brandonrozek.com`,
|
||||
then the service will perform a GET request at
|
||||
`https://brandonrozek.com/.well-known/webfinger?resource=acct:brozek@brandonrozek.com`.
|
||||
|
||||
A webfinger request should return the handle of the user (the `subject`) as well as
|
||||
a link to its `actor`.
|
||||
|
||||
```json
|
||||
{
|
||||
"subject": "acct:brozek@brandonrozek.com",
|
||||
|
||||
"links": [
|
||||
{
|
||||
"rel": "self",
|
||||
"type": "application/activity+json",
|
||||
"href": "https://brandonrozek.com/brozek.json"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
Now for a static site with one user, you can hardcode the webfinger directly
|
||||
at `.well-known/webfinger`. The only issue is that many webservers determine the
|
||||
mimetype of a file by its extension. In this case, we'll have to let the webserver
|
||||
(mine is nginx) know how to serve it.
|
||||
|
||||
```nginx
|
||||
location /.well-known/webfinger {
|
||||
default_type application/jrd+json;
|
||||
add_header Access-Control-Allow-Origin "*";
|
||||
}
|
||||
```
|
||||
|
||||
## Actor
|
||||
|
||||
An actor defines how to interact with a user as well as its metadata.
|
||||
This file also needs to be served with the `application/jrd+json` header.
|
||||
Below is an example of what I have on my website as well as how it looks
|
||||
on Mastodon.
|
||||
|
||||
```json
|
||||
{
|
||||
"@context": [
|
||||
"https://www.w3.org/ns/activitystreams",
|
||||
"https://w3id.org/security/v1"
|
||||
],
|
||||
"id": "https://brandonrozek.com/brozek.json",
|
||||
"type": "Person",
|
||||
"inbox": "https://brandonrozek.com/inbox",
|
||||
"outbox": "https://granary.io/url?input=rss&output=as2&url=http%3A%2F%2Fbrandonrozek.com%2Fblog%2Findex.xml",
|
||||
"preferredUsername": "brozek",
|
||||
"name": "Brandon Rozek",
|
||||
"summary": "<p>Writings from <a href='https://brandonrozek.com'>https://brandonrozek.com</p></a><p>Social profile <a href='https://fosstodon.org/@brozek'>@brozek@fosstodon.org</a></p>",
|
||||
"url": "https://brandonrozek.com",
|
||||
"manuallyApprovesFollowers": false,
|
||||
"discoverable": true,
|
||||
"published": "2022-05-17T00:00:00Z",
|
||||
"icon": {
|
||||
"type": "Image",
|
||||
"mediaType": "image/jpeg",
|
||||
"url": "https://brandonrozek.com/img/avatar.jpg"
|
||||
},
|
||||
"publicKey": {
|
||||
"id": "https://brandonrozek.com/brozek.json#main-key",
|
||||
"owner": "https://brandonrozek.com.com/brozek.json",
|
||||
"publicKeyPem": "-----BEGIN PUBLIC KEY-----...-----END PUBLIC KEY-----"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Limitations and Conclusion
|
||||
|
||||
Notice in the previous screenshot that it says "Cancel Follow Request".
|
||||
This is because my static website is not equipped to handle a follow request.
|
||||
Standard ActivityPub servers keep an inventory of all the users that follow
|
||||
their users and who each user on the server is following.
|
||||
|
||||
The outbox defines items that the user has published.
|
||||
I have it pointed to an activity JSON feed generated directly
|
||||
from my RSS using granary.io.
|
||||
Mastodon correctly displays the number of blog posts I have,
|
||||
but sadly it does not show any of them. I'm not entirely
|
||||
sure why, though my hypothesis is that the posts need to be pushed
|
||||
to the Mastodon server when its created. It could also be that the
|
||||
actor isn't defined properly in the activity JSON feed. If you happen
|
||||
to know please get in touch.
