data-api-dataの形式変更対応#

html5版再生ページがまた変わったので対策。mediaTypeとwatchAuthKeyとcsrfTokenが見当たらんが、大丈夫かな？
smile鯖が403返す現象の対策が不明なので、今のところDMC対応必須。例によってeco/非プレは未確認。
Niconicomeの修正内容を参考にさせていただいた。

1. nFinder2 → nFinder2.exe → TrinityCS → Scrape を開く
2. 「SmileVideoInfoDataClass GetVideoInfoHTML_Zero」を検索
3. Edit Method (C#)...
4. 1個目の「catch」のすぐ下にある「{」と「}」の間に下記を挿入
(https://writening.net/page?C6unDM の対応をしている人は、その際に足した分を消して下記を入れなおす。)

foreach (HtmlNode htmlNode2 in ((IEnumerable<HtmlNode>)htmlDocument.DocumentNode.SelectNodes("//div[@id=\"js-initial-watch-data\"]")))

5. Compileを押す
6. 「Identifier expected」等のエラーが下に出るので、そこをダブルクリック
7. 赤い「o__SiteContainer0」ってのがある行に移動するので、
その2行上の「// Token: ...」の行から、「p__Site3」がある行の1行下の「}」までを削除。
(そこより後ろに「}」がもう2個あるけどそれらは残す)
8. Compileを押す。今度は成功するはず。
9. Save AllでnFinder.exeを保存
10. nico.rbに「exit(1) if json["video"]["dmcInfo"].nil?」 という行がある場合は削除
11. nico.rbの「dmc_info = json["video"]["dmcInfo"]["session_api"]」の行から
「"priority":dmc_info["priority"]}}.to_json」の行まで(24行くらい)を削除、下記に差し替える

exit(1) if json["media"].nil?
exit(1) if json["media"]["delivery"].nil?
dmc_info = json["media"]["delivery"]

req_body =
{"session":{"recipe_id":dmc_info["recipeId"],
"content_id":dmc_info["movie"]["contentId"],
"content_type":"movie",
"content_src_id_sets":[{"content_src_ids":[{"src_id_to_mux":{
"video_src_ids":dmc_info["movie"]["session"]["videos"],
"audio_src_ids":dmc_info["movie"]["session"]["audios"]}}]}],
"timing_constraint":"unlimited",
"keep_method":{"heartbeat":{"lifetime":dmc_info["movie"]["session"]["heartbeatLifetime"]}},
"protocol":{"name":"http",
"parameters":{"http_parameters":{"parameters":{"http_output_download_parameters":{"use_well_known_port":"no",
"use_ssl":"no"}}}}},
"content_uri":"",
"session_operation_auth":{"session_operation_auth_by_signature":{
"token":dmc_info["movie"]["session"]["token"],
"signature":dmc_info["movie"]["session"]["signature"]}},
"content_auth":{"auth_type":dmc_info["movie"]["session"]["authTypes"]["http"],
"content_key_timeout":dmc_info["movie"]["session"]["contentKeyTimeout"],
"service_id":"nicovideo",
"service_user_id":dmc_info["movie"]["session"]["serviceUserId"]},
"client_info":{"player_id":dmc_info["movie"]["session"]["playerId"]},
"priority":dmc_info["movie"]["session"]["priority"]}}.to_json

12. nico.rbに「"originalTitle"」と書かれているとこが一か所あるので「"title"」に変更
