Wiremock JSON proxyBaseUrl with one value change in response - wiremock

Question

I want to achieve a proxy from another url with changing one value within the response
So having something like that (not working, just an idea)
{
"request": {
"method": "GET",
"urlPathPattern": "/api/search-service"
},
"response": {
"proxyBaseUrl" : "https://external-search-service",
"transformerParameters": {
"results[*].hasAccess": true
}
}
}
}
When you call GET https://external-search-service/api/search-service the response is
{
"meta": {
"results": 2
},
"results": [
{
"id": "1",
"path": "/path/1",
"hasAccess": false
},
{
"id": "2",
"path": "/path/2",
"hasAccess": false
}
]
}
And when I want to temper with response using wiremock when you call GET https://wiremock/api/search-service the response I expect is
{
"meta": {
"results": 2
},
"results": [
{
"id": "1",
"path": "/path/1",
"hasAccess": true
},
{
"id": "2",
"path": "/path/2",
"hasAccess": true
}
]
}
How this can be achieved with JSON notation?

This isn't achievable purely using JSON configuration, but you can create a Java extension to transform responses, which will work with proxied responses.
To do this you would need to create an implementation of ResponseTransformer and register it with WireMock on startup.
Full details of how to do this are here: https://wiremock.org/docs/extending-wiremock/#response-transformation
