在`Pair <K，V>`中指定<K，V>类型

Question

How can I get rid of these as String casts?

What I want to do is to change the fun definition but I'm not sure how to do it... to include String in there

 parametersOf("appKey" to "asdas3334", "token" to "433432")

/**
 * Returns a new [Parameters] with the specified contents, given as a list of pairs
 * where the first component is the key and the second is the value.
 */
fun <K, V> parametersOf(vararg pairs: Pair<K, V>): Parameters {

    val p = Parameters(pairs.size)

    for ((key, value) in pairs)
        p.put(key as String, value as String)

    return p
}

Answer 1

Just get rid of the generic definition and use a Pair<String, String> :

fun parametersOf(vararg pairs: Pair<String, String>): Parameters {

    val p = Parameters(pairs.size)

    for ((key, value) in pairs)
        p.put(key, value) 

    return p
}
