設定
ハンドラはファイル名.関数名で指定する
SlackでImcomingWebHookを追加する
コード
- ググってでてくるrequestsというモジュールは、urllibの中に吸収されたみたい
- jsonをslackのWEBHOOK用のアドレスにPOSTで投げる
def lambda_handler(event, context):のeventはLambda実行時に関数へ引き渡されるJSONデータ- 実行元のリソースによってもちろん中身は違うが、JSONデータなのでテンプレート的に扱うことができる

動作確認
lambdaからテストを実行
- この際にテストするJSON文字列は適当で良い（コードの中で利用していないから）
