直接打 API Gateway
在 Part3 中，Deployment 完時，CloudFomration 的 Output 可以看到 ApiGateway 的 URI。如果沒有記住，我們也可以在 AWS Console 中的 API Gateway Stage 找到 URI
找到 URI 以後，可以直接使用 CURL 做測試
1$ curl https://t3faydf1rb.execute-api.ap-northeast-1.amazonaws.com/Prod/hello
2{"message":"hello world"}%
取得執行 Log
透過 AWS Console
AWS Lambda 預設會建立 CloudWatch Log Group，我們可以在 CloudWatch 中的 Log Group 找到 Lambda 執行的 Log。
預設的 Log Group 名字是 /aws/lambda/<function name>
在 Log Steam 裡面，可以找到艾倫在 Part3 中，修改 Lambda Function Code 時，所印出 Event 的 Log
SAM Log
1$ sam logs -n HelloWorldFunction --stack-name sam-app --tail
2You can now use 'sam logs' without --name parameter, which will pull the logs from all supported resources in your stack.

使用 SAM 測試雲上 Lambda Function
除了使用基本的 Curl 以外， SAM remote 讓我們可以直接在地端觸發雲上的 Lambda Function ，並且提供一些額外的資訊，例如 billedDurationMs 等
1$ sam remote invoke
