Response Templating

If you need to build a response dynamically based on the request data, you can do so using templating:

hoverfly.importSimulation(dsl(
    service("www.my-test.com")

        // Using path in template
        .get("/api/bookings/1")
        .willReturn(success().body(jsonWithSingleQuotes(
                "{'id':{{ Request.Path.[2] }},'origin':'London','destination':'Singapore','_links':{'self':{'href':'http://localhost/api/bookings/{{ Request.Path.[2] }}'}}}"
        )))

        // Using query Param in template
        .get("/api/bookings")
            .queryParam("destination", "London")
            .queryParam("page", any())
        .willReturn(success().body(jsonWithSingleQuotes(
                "{'id':'1', 'destination':'{{ Request.QueryParam.destination }}','_links':{'self':{'href':'http://localhost/api/bookings?page={{ Request.QueryParam.page }}'}}}"
        )))));

The first example sets the id in response body based on the last path segment in the request using {{ Request.Path.[2] }}. The second example sets some response body data based on the request param using {{ Request.QueryParam.destination }} and {{ Request.QueryParam.page }}.
