GraphQL endpoint: http://127.0.0.1:8888/graphql
WebSocket endpoint: ws://127.0.0.1:8888/graphql/ws
Try these operations once the servers are up:

=== gRPC Backend (via GraphQL) ===
  query { hello(name:"GraphQL") { message meta { correlationId from { id displayName trusted } } } }
  mutation { updateGreeting(input:{ name:"GraphQL", salutation:"Howdy" }) { message } }
  subscription { streamHello(name:"GraphQL") { message meta { correlationId } } }
  query { user(id:"demo") { id displayName trusted } }

=== REST Connector (JSONPlaceholder API) ===
The gateway includes a REST connector for https://jsonplaceholder.typicode.com
You can execute REST endpoints programmatically via the connector:

  // In your resolver or middleware:
  let connector = gateway.rest_connectors().get("jsonplaceholder").unwrap();
  let result = connector.execute("getPost", args).await?;

Test the REST connector directly with curl:
  curl https://jsonplaceholder.typicode.com/posts/1
  curl https://jsonplaceholder.typicode.com/users/1

=== File Uploads ===
  # Upload (multipart): see README for the curl example
  # Multi-upload (multipart): see README for the curl example

NOTE: Query whitelisting is enabled in WARN mode.
      Non-whitelisted queries will log warnings but still execute.
      Set WhitelistMode::Enforce in production for strict security!

NOTE: REST connector is configured for JSONPlaceholder API demo.
      Use add_rest_connector() to integrate your own REST APIs!
