Wiremock Standalone with Dynamic response

Question

I have a standalone instance of Wiremock server. The mappings are stored as json files under the mappings folder. I have a POST request that needs to return a dynamic ID(integer) in the response. Is there a way to configure this in the json file?

Answer 1

This seems like a perfect use-case for OpenTable's Wiremock Body Transformer.

It can be easily integrated with the Standalone Server like this:

java -cp "wiremock-body-transformer-1.1.6.jar:wiremock-2.3.1-standalone.jar" com.github.tomakehurst.wiremock.standalone.WireMockServerRunner --verbose --extensions com.opentable.extension.BodyTransformer

And allows you to easily specify a dynamic variable that you would want to match in the response.

Here is an example to get a random integer without having to specify anything in the request, however if you need to match a specific variable in the request to the response, then that is also very doable with this extension and numerous examples can be found in the readme.

{
    "request": {
        "method": "POST",
        "urlPath": "/transform",
    },
    "response": {
        "status": 200,
        "body": "{\"randomInteger\": \"$(!RandomInteger)\"}",
        "headers": {
            "Content-Type": "application/json"
        },
        "transformers": ["body-transformer"]
    }
}
