ニコニコ再開(8/5)への対応

公式アナウンス

対応方針

• ニコ動関連は優先してやるつもり。８月中に対応してやるぞの気持ち
• だけどニコ生関連は対応モチベ低いので 大幅な改修が必要な場合には 対応スピードは遅くなるやも
• 緊急メンテが何度も起きる前提でサービス稼働状況が確認しやすい表示に対応したい

消すだけなのでそう大変さはなさそう。先んじてNiconicoTookitからCommunity関係の削除作業を進めておく。

データ取得が視聴ページHTMLからAPI直取得に変更

https://www.nicovideo.jp/watch/{VideoId}?responseType=json

以下は非ログイン（ゲスト）状態での取得例です。 長いので折りたたみ表示にしてます。

レスポンス例：通常の動画

動画視聴までの大まかな流れは変わっていません。最初の動画視聴データ取得部分だけ前のコメントの通り変化してます。

以前までの手順は以下から確認できます
#961 (comment)

2024/8/5 以降における視聴までの手順は次の通りです

1. https://www.nicovideo.jp/watch/{VideoId}?responseType=json からレスポンスされるjsonをパース
2. jsonの media.domand.videos および media.domand.audios から任意の動画と音声のクオリティを選択
3. https://nvapi.nicovideo.jp/v1/watch/{{video.id}}/access-rights/hls?actionTrackId={{videoAds.additionalParams.watchTrackId}} にPOST
   3.1 リクエストヘッダーに以下を追加
   3.1.1 キー：X-Access-Right-Key 値：{{media.domand.accessRightKey}}
   3.1.2 キー：X-Frontend-Version 値：0
   3.1.3 キー：X-Frontend-Id 値：6
   3.1.4 キー：X-Request-With 値：https://www.nicovideo.jp
   3.2 リクエストコンテンツに以下を設定
   3.2.1 json {"outputs":[["video-h264-144p","audio-aac-128kbps"]]}
   3.2.2 画質・音質の値は media.domand.videos 等の id を指定します
   3.3 actionTrackIdは必須です。無い場合は失敗します
4. レスポンスされたjson の data.contentUrl を用いてメディア再生を行う

(3)のレスポンス例

{
  "meta": {
    "status": 201
  },
  "data": {
    "contentUrl": "https://delivery.domand.nicovideo.jp/hls/654b11200d7d2ef695f075ba/playlists/variants/1e1d32ffbbec3289.m3u8",
    "createTime": "2023-11-10T17:00:28+09:00",
    "expireTime": "2023-11-11T17:00:28+09:00"
  }
}

• 動画視聴関連のAPIが変わっていたので対応しました
• ニコレポはメニュー上から消しただけで内部的にはまだ残ってます
• チャンネルとコミュニティ周りは全くチェックしてません
• 生放送も視聴できるようですがそれ以外は未確認です
