hi guys, i want to ask related to make a callback to kafka i already tried using

serveEventListeners

for the rest api, but is there any way to achieve with kafka? thankyouu!!

{
  "request": {
    "urlPath": "/something-async",
    "method": "POST"
  },
  "response": {
    "status": 200,
    "body": "{ \"result\": \"SUCCESS BRO\" }"
  },
  "serveEventListeners": [
    {
      "name": "webhook",
      "parameters": {
        "method": "POST",
        "url": "<https://reqres.in/api/users>",
        "headers": {
          "Content-Type": "application/json"
        },
        "body": "{\"name\":\"juragan\",\"job\":\"jaga empang\"}"
      }
    }
  ]
}

There's nothing readily built to do this right now but you could write your own serve event listener implementation that posts Kafka messages, using the built-in webhook listener for inspiration.

im new to wiremock, and this is dummy question can i add import something like this? seems i need this to achieve sending messages to kafka

import javax.jms.Connection;
import javax.jms.Destination;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.TextMessage;

I’m not a Kafka expert, but I’d expect you’d want to use the official Kafka Java client in your event listener rather than JMS classes, unless you’re using some kind of JMS to Kafka bridge in your org?

yeah i think better using kafka java client, at the end i just do callback on API rest side

I was thinking about this the other day as it happens - that we don’t expose Faker’s locale parameter in the extension at the moment. Unfortunately the only immediate way round this is forking the extension, but I’d definitely be happy to accept a PR that added a locale parameter onto the helper.

is the faker is in this repo ?

We’ve adopted it now, so this one: https://github.com/wiremock/wiremock-faker-extension

oh hi @Tom the team are already good with locale

US

but how to integrate into our json mappings? is it on docker compose or with command line i already put the

jar

inside the

extensions

folder is it the right way? because i was tried and somehow it doesnt works

You will have to add the extension via the

--extensions

parameter. The extensions that are loaded are displayed when WireMock starts up so you will be able to see it when it is loaded. Let me see if I can dig out what you will need

i already specify it on

docker-compose.yml

but it didnt shoown up

Seems the faker extension doesn’t have the service loader file at the moment so you’ll need to add

--extensions org.wiremock.RandomExtension

to your entrypoint

alright will try now

Have you tried separating the commands out:

entrypoint: [ "/docker-entrypoint.sh", "--verbose" , "--extensions", "org.wiremock.RandomExtension" ]

i tried, and then this error comes up somehow the extensions is not loaded right?

Are you mapping the extensions directory?

Suggests that somehow the faker JAR file hasn’t been added to the classpath

yap already mapped

Your entrypoint script seems to be running Docker in Docker. How about just using the default one in the wiremock image and passing the extra CLI parameters to it?

so just remove the

docker-entrypoint.sh

and try again yes?

Yep, think that should do it

yup sorted it out but the another issue is come i managed using this command

docker run -it --rm \
  -p 8080:8080 \
  --name wiremock \
  -v $PWD/extensions:/var/wiremock/extensions \
  -v $PWD/__files:/var/wiremock/__files \
  -v $PWD/mappings:/var/wiremock/mappings \
  wiremock/wiremock \
    --extensions org.wiremock.RandomExtension, org.wiremock.RandomHelper

but when i hit the endpoint it shows

2024-02-28 12:10:45.205 No response could be served as there are no stub mappings in this WireMock instance.

Good stuff. Glad it is all sorted
