[SOLVED] With wiremock how can I match against the wiremock server URL in the body of a POST?

With wiremock how can I match against the wiremock server URL in the body of a POST?

I'm using Wiremock with a client calling the OSISoft PI Web API and I'm having issues matching against the POST body to the request defined here as with Wiremock the POST body will have a URL containing the randomly generated port. e.g.

{
  "1": {
    "Method": "POST",
    "Resource": "http://localhost:24353/piwebapi/assetdatabases/D0NxzXSxtlKkGzAaZhKOB-KABJ2buwfWrkye3YhdL2FOUAUEhMQUZTMDRcQgYUUEVSRk9STUFOQ0UgVEVTVElORw/elements",
    "Content": "{\"Name\":\"New Element\"}"
  }
}

How can I match against the URL in the Resource element where the port number will change between test runs? Obviously I cannot use templating for requests like I would with responses.

From reviewing the docs on request matching I see that using equalToJson with placeholders or matchesJsonPath with a regex expression may be an option but I'm not clear on the exact syntax. Or is there a simpler option that I'm missing?

If you don't need to match anything in particular for that element you could use a JSON placeholder e.g. "Resource": "${json-unit.any-string}".

If you do need to match the part after the port number then you can use the regex form e.g.: "Resource": "${json-unit.regex}.*/piwebapi/assetdatabases/D0NxzXSxtlKkGzAaZhKOB-KABJ2buwfWrkye3YhdL2FOUAUEhMQUZTMDRcQgYUUEVSRk9STUFOQ0UgVEVTVElORw/elements"}"
