May I ask that is there any configuration or solution which could fetch and log the request body in log file?

Hi there,

The kong-ingress-controller and kong have been deployed to my K8S cluster via
kubectl apply -f https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/master/deploy/single/all-in-one-dbless.yaml as the first step.

And, there is a plugin named file log via https://docs.konghq.com/hub/kong-inc/file-log/ installed as the global plugin, also.

The final step is that my sample application deployed to the K8S cluster.

When I would like to test to POST an endpoint of my sample application via:

curl -X POST -H "Content-Type: application/json" -d '{"user_id": "123", "coin":100, "success":1, "msg":"OK!" }' localhost/sayHello1 | jq .

The result of file-log plugin is

My concern is that is there any incorrect steps what I made, since, there is no request body ({"user_id": "123", "coin":100, "success":1, "msg":"OK!" }) logged in the "request" section of result?

My sample application is a simple rest controller of spring-boot as below, I could see the output in the application console.
@PostMapping(
value = "/sayHello1",
consumes = MediaType.APPLICATION_JSON_VALUE,
produces = MediaType.APPLICATION_JSON_VALUE)
public void sayHello1(@RequestBody Map<String, Object> params) {
System.out.println(params);
}

hi there,

Sorry for interrupting you, again.

Is it possible to add the response body within the response section?
Such as one endpoint of my sample application is /hello, which returns a string with the value of ‘say hello2.0-gitlab’ . Will the string value be added into the response section, also?

Sorry for your inconvenience.
