Is it possible to use the ktor HTTP client to parse x-www-form urlencoded responses to models, similar to how it parses JSON?

I am also looking for a way to do this

+1 for me, from what I've gathered so far you could use call.receiveParameters() to get what is basically a Map<String, List<String>> to work with. This doesn't automatically parse into models like the JSON converters.

To use the syntax of call.receive<MyDataModel>() with x-www-form-urlencoded we need to use the ContentNegotiation feature and write our own converter to do the mapping:

install(ContentNegotiation) {
    register(ContentType.Application.FormUrlEncoded, FormUrlEncodedConverterThatNeedsWriting())
}

I'm knew to Kotlin so I haven't managed to write a converter to handle form data in the same way as something like Ruby on Rails does using [ ] as delimiters.

I've made this gist from the JacksonConverterTest incase someone is able to help: https://gist.github.com/createdbypete/ac57c6b59133b184799fadbf32b4b93a
