backlog webhookを使ってpull-requestをslackに通知してみる

Last updated at Posted at 2016-04-15

はじめに

  • ゆるふわです

あわせて読みたい

ゴール

  • backlogのwebhookのイベント(pull-request作成、更新、コメント)をサーバー上のgolangで受け付けてslackのincoming webhookにリクエストする

公式ドキュメントでjson定義探す

Webhookでは、指定されたURLにデータをJSON形式でPUSHで送信します。JSONデータの属性は一部の共通部分を除き、イベントによって異なるためテスト実行等で確認して下さい。

URL送ったところで力尽きたorz

感想戦

  • json調べるのにほぼほぼの時間を使った
  • プロジェクト配下のすべてのリポジトリのpull-requestがwebhookで送られてくるので不要なものを無視するのがひと手間
  • コメントごとにslackに通知が来るのはだいぶノイズなのでn分間隔でpoolして重複は除去して通知とかやりたい(やるとはいってない
