Use template (Pass-through Service) to forward the request that the passthrough resource received to the backend.
When forwarding, the request is made using the same HTTP method that was used to invoke the passthrough resource
- Pull the template from central
bal new -t choreo/simple_passthrough <newProjectName>
Run the Ballerina project created by the service template by executing bal run from the root.
Once successfully executed, Listener will be started at port 8090. Then you need to invoke the service using the following curl command.
$ curl -d '{json}' -H 'Content-Type: application/json' http://localhost:8090/.
Now service will be invoked and returns data as
{"args":{}, "data":"{json}", "files":{}, "form":{}, "headers":{"x-forwarded-proto":"https", "x-forwarded-port":"443", "host":"postman-echo.com", "x-amzn-trace-id":"Root=1-61a64b4c-1bcb492d2fd2d5c37370a357", "content-length":"6", "accept":"*/*", "content-type":"application/json", "user-agent":"ballerina"}, "json":null, "url":"https://postman-echo.com/post/"}
