AWS Lambdaの`event`を確認

API GatewayのGETメソッドでAWS Lambda関数を統合している場合に、eventで受け取る値を確認しました。

以下のような#AWS Lambdaを実行しました。

export const handler = async (event) => {

  console.log(JSON.stringify(event));

  const response = {
    statusCode: 200,
    body: JSON.stringify('Hello from Lambda!'),
  };
  return response;
};
