OpenAPI GreeterClient Demo
The openapi.client operator can call arbitrary REST services from a graph.
Configure and Run the Graph
Follow the steps below to run the example from the Data Pipeline UI:
- Start the openapi.server greeter demo graph (com.sap.demo.openapi.server.greeter), which exposes its service at path /openapi/service/samples/greeter relative to the vflow instance URL.
- Verify the host and port configured for this demo graph matches the actual vflow instance.
- Start this demo graph, which will automatically start invoking a series of operations.
- Open the UI from the wiretap operator so that the response messages from the invoked operations are displayed on the browser.
