手動ActivityPub

okuoku

まずは手動で見てみるのが良いかな。TelnetでHTTP叩いてた時代と変わらない味。とりあえずMisskey.ioにアカウントを用意した。

https://misskey.io/@okuokutest

EDIT: これをやりたい

okuoku

WebFinger

https://webfinger.net/lookup/?resource=https%3A%2F%2Fmisskey.io%2F%40okuokutest -- プロフィールページ
https://webfinger.net/lookup/?resource=acct%3A%40okuokutest%40misskey.io -- acct:@okuokutest@misskey.io

どちらも同じ内容が取れる。

{
  "subject": "acct:okuokutest@misskey.io",
  "links": [
    {
      "rel": "self",
      "type": "application/activity+json",
      "href": "https://misskey.io/users/9czxp5d7tk"
    },
    {
      "rel": "http://webfinger.net/rel/profile-page",
      "type": "text/html",
      "href": "https://misskey.io/@okuokutest"
    },
    {
      "rel": "http://ostatus.org/schema/1.0/subscribe",
      "template": "https://misskey.io/authorize-follow?acct={uri}"
    }
  ]
}

普通だな。 https://misskey.io/users/9czxp5d7tk がActorのURLになる。

Actorオブジェクトの取得

$ curl --header "Accept: application/activity+json" https://misskey.io/users/9czxp5d7tk | jq .

Curlで拾ってくる。pretty-printは jq で適当に。。仕様としては Accept ヘッダは application/ld+json; profile="https://www.w3.org/ns/activitystreams" らしい(MUST)。

Outboxは https://misskey.io/users/9czxp5d7tk/outbox にあることがわかる。

ノートの取得

Outboxは OrderedCollection なので、 https://misskey.io/users/9czxp5d7tk/outbox を application/activity+json で GET して得られるのは:

{
...
  "id": "https://misskey.io/users/9czxp5d7tk/outbox",
  "type": "OrderedCollection",
  "totalItems": 1,
  "first": "https://misskey.io/users/9czxp5d7tk/outbox?page=true",
  "last": "https://misskey.io/users/9czxp5d7tk/outbox?page=true&since_id=000000000000000000000000"
}

first のURLを拾うと:
