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 at https://docs.osisoft.com/bundle/pi-web-api-reference/page/help/controllers/batch/actions/execute.html 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?

Thanks,
Mark

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"}"
