JarCastingjson-ktor-client
JSON functionality for ktor HTTP clients
This library provides ktor client interface integration for the json-kotlin library.
Quick Start
In the HttpClient engine specification, use:
val client = HttpClient(HttpClientEngine) {
Json {
jsonKtorClient {}
}
}
Customizations (e.g custom serialization or deserialization) may be specified within the lambda supplied to the jsonKtorClient function:
val client = HttpClient(HttpClientEngine) {
Json {
jsonKtorClient {
fromJSON { json ->
require(json is JSONObject) { "Must be JSONObject" }
Example(json.getString("custom1"), json.getInt("custom2"))
}
}
}
}
For more details see the json-kotlin library.
Streaming Input
From version 0.2 onwards, this library uses the json-streaming library for on-the-fly JSON parsing. This means that the input data is parsed into an internal form as it is being read, and avoids the need to allocate memory for the entire JSON text.
Streaming Output
From version 0.5, the library will (optionally) stream output using a non-blocking output library (json-kotlin-nonblocking).
More documentation will be available shortly; in the meantime the unit test classes contain examples.

The latest version of the library is 0.7, and it may be obtained from the Maven Central repository.
