【第十五天】突發任務：Twitch API

在我們和自己的機器人對話之前，先把昨天提到的twitch實作吧！先熱熱手！
恩～看來不像想像中的順利，再仔細看的時候發現了這個！

所以我們又找到了他的API！
沒錯！又是一個新的玩具！那我們就用他提供的API來完成我們的需求吧！

~~看來進度又多Delay一天了~~

那就先來註冊拿Client吧！點我

接著！直接看這份文件！
千萬別在新版API上逗留！他是時間小偷啊！
~~簡單說，以新版API我們無法從channelName就GET到我們想要的資訊！~~

新版本的串接方式請參考第二十四天

雖然他說`Twitch API v5`只支援到2018年年尾！但反過來說我們有整整一年都可以用這隻API用妥妥的！

所以API要怎麼打呢？

curl -H 'Client-ID: <你剛剛拿到的ClientID>' -X GET 'https://api.twitch.tv/kraken/streams/?channel=<channelName>'

channelName指的是這個

以實況主nightblue3為例子，打出來的API會是長這樣！

    }
  ],
  "_links": {
    "self": "https://api.twitch.tv/kraken/streams?channel=nightblue3&limit=25&stream_type=live",
    "next": "https://api.twitch.tv/kraken/streams?channel=nightblue3&limit=25&offset=25&stream_type=live",

    "summary": "https://api.twitch.tv/kraken/streams/summary",
    "followed": "https://api.twitch.tv/kraken/streams/followed"
  }
}

那我們再用一個目前沒開實況的小熊為例子

{
  "_total": 0,
  "streams": [],
  "_links": {
    "self": "https://api.twitch.tv/kraken/streams?channel=yuniko0720&limit=25&stream_type=live",
    "next": "https://api.twitch.tv/kraken/streams?channel=yuniko0720&limit=25&offset=25&stream_type=live",
    "featured": "https://api.twitch.tv/kraken/streams/featured",
    "summary": "https://api.twitch.tv/kraken/streams/summary",
    "followed": "https://api.twitch.tv/kraken/streams/followed"
  }
}

這樣就可以分辨出是否有開實況的差別了！
那我們來試著整理出一份它的Service吧！

PR在此可供參考～

今天成果大概是這樣
