■目的
今目論んでいるアプリでは、ユーザーみんなで動画を共有出来たらいいなぁって考えてる。
ただ動画をサーバーにアップしてると容量も食うし、管理も大変そう。
なのでYoutubeにアップして、それのリンクをサイトでみられるようにする方針にしようと思う。
Youtubeをそのまま利用すればいいんじゃな？って意見もありそうですが、過去のデータとかを管理するのがやりにくそうなんで。
あとは純粋なAPIを使ってみたいと言う興味です！
■やってみよう
今回はこちらのサイトを参考にしました。
https://developers.google.com/youtube/v3/guides/uploading_a_video?hl=ja
どうやらAPIを使うにはGoogleのアカウントが必要らしい。
ログインして、以下に飛ぶ
https://console.developers.google.com/apis/
APIライブラリからYoutube Data API v3を有効化
次に認証情報の追加を求められるので入力してキー取得
そこからさらに、使うドメインとか登録してOAuthクライアントIDを入手
多分Googleアカウントの用意は出来たのでPythonさんにpip
pip install google-api-python-client
なんか古そうなのでこっちにした
■上手くいかないので別のサイトを参考にしよう

■エラーは以下のような内容が出てた。

Uploading file...
An HTTP error 403 occurred:
b'{\n "error": {\n "errors": [\n {\n "domain": "youtube.quota",\n "reason": "quotaExceeded",\n "message": "The request cannot be completed because you have exceeded your \\u003ca href=\\"/youtube/v3/getting-started#quota\\"\\u003equota\\u003c/a\\u003e."\n }\n ],\n "code": 403,\n "message": "The request cannot be completed because you have exceeded your \\u003ca href=\\"/youtube/v3/getting-started#quota\\"\\u003equota\\u003c/a\\u003e."\n }\n}\n'
要約すると、1日にリクエストできる容量（quota）を超えたとのこと。
調べると一日あたり10,000 quotaで動画一個あたり1600quotaとのこと。
少ない。。。
quotaの容量を増やすためには、何か登録が必要とのこと。
めんどくさいのでAPIでYoutubeアップロード はここで終焉とする。
