Android: Parse API response in field1=value1&field2=value2 format

Question

An API I'm calling using a non-json format. In the response, I get something like this.

field1=value1&field2=value2&field3=value3

What is this format called? It looks exactly like what you would send in a query usually. I would like to parse this response using Retrofit.

Any ideas? Thank you.

Here is an extension function to parse it into a map. After that it's easy to grab the fields by doing map["field1] for example.

fun String.parseQueryFormat() : Map<String, String>{
    val queryPairs: MutableMap<String, String> = LinkedHashMap()
    val pairs = this.split("&").toTypedArray()
    for (pair in pairs) {
        val idx = pair.indexOf("=")
        queryPairs[URLDecoder.decode(pair.substring(0, idx), "UTF-8")] = URLDecoder.decode(pair.substring(idx + 1), "UTF-8")
    }
    return queryPairs
}

.

val responseString = responseBody.string()
val map = responseString.parseQueryFormat()
val field1 = map["field1"]
val field2 = map["field2"]
