This tutorial assumes that we build the petstore API with .NET, Python, or Nodejs without any cross-cutting concerns. Let’s put the light-gateway instance on the localhost to access the petstore API to address all the cross-cutting concerns.
First, let’s start the Petstore API and ensure it is working. The default config should have the petstore service started at 9443 with HTTPS/2.
java -jar target/server.jar
Second, let’s send a request to the petstore server to ensure it is working.
