ローカルでテスト

サーバーの起動

functions-framework --target=sum_up

curl でテスト

curl_post_local.sh

curl -X POST $HOST \
 -H "Content-Type: application/json" \
 -d '{"aa": 32, "bb": 58}'
echo ""

Httpie でテスト

http_post_local.sh

HOST="http://localhost:8080"
http $HOST \
  aa=12 bb=45

Cloud Functions でテスト

デプロイ

gcloud functions deploy function-apr06 \
--entry-point=sum_up \
--trigger-http \
--runtime=python39 \
--region asia-northeast1

curl でテスト

HOST="https://asia-northeast1-project-apr06.cloudfunctions.net"
curl -X POST $HOST/function-apr06 \
 -H "Content-Type: application/json" \
 -H "Authorization: bearer $(gcloud auth print-identity-token)" \
 -d '{"aa": 123, "bb": 546}'
