WireMock

Hi everyone,
I’m working on a WireMock Mapping and would be super grateful for some help. The WireMock receives a Request with a JWT as query parameter `code`. I use `serveEventListeners` to trigger a call. This call needs to extract the `sub` claim from the JWT and include it as `user_id` to body. I tried it with the jwt plugin like this `{{jwt path='sub' token=originalRequest.query.code}}` but it generated a new jwt, what is not really what I need. Is there any way to only extract that claim from the token?

Here is the `serveEventListeners` part of my mapping:
``` "serveEventListeners": [
    {
      "name": "webhook",
      "parameters": {
        "method": "POST",
        "url": "<https://example.org/event-listener>",
        "body": "{\"id\": \"{{randomValue type='UUID'}}\", \"user_id\": \"{{jwt path='sub' token=originalRequest.query.code}}\""
      }
    }
  ]```

It’s fiddly to deconstruct JWTs at the moment, but it can be done:

```{{#formatJson}}
{{regexExtract request.query.code '(.*?)\.(.*?)\.(.*?)' 'parts'}}
{{val (base64 parts.1 decode=true) assign='jwtBody'}}
{{val (jsonPath jwtBody '$.sub') assign='sub'}}
{
  "user_id": "{{sub}}"
}
{{/formatJson}}```

Hey Tom, thanks for your help. That worked :ok_hand:
