https://github.com/ymotongpoo/go-twitter 使って手探りで Twitter のメンション取得するの書いてみた。それだけなのもアレなので json から設定取ってくるみたいにした。

conf.json

{
  "Twitter": {
    "ConsumerKey": "yourConsumerKey",
    "ConsumerSecret": "yourConsumerSecret",
    "AccessToken": "yourAccessToken",
    "AccessTokenSecret": "yourAccessTokenSecret"
  }
}
