The best situation is to provide fixed values but sometimes you need to reference a request in your response. In order to do this you can profit from the fromRequest() method that allows you to reference a bunch of elements from the HTTP request. You can use the following options:
- `fromRequest().url()` - return the request URL
- `fromRequest().query(String key)` - return the first query parameter with a given name
- `fromRequest().query(String key, int index)` - return the nth query parameter with a given name
- `fromRequest().header(String key)` - return the first header with a given name
- `fromRequest().header(String key, int index)` - return the nth header with a given name
- `fromRequest().body()` - return the full request body
- `fromRequest().body(String jsonPath)` - return the element from the request that matches the JSON Path
