Is there any websocket ktor client example, in which the entry object is available so it can be used to cancel or start the websocket session. So far, there is that example where you manage the websocket session within a scoped block of code and it isn't available to the outside world.

httpClient.wss(
    method = HttpMethod.Get,
    host = "<http://echo.websocket.org|echo.websocket.org>",
    port = 8090,
) {
    // this is of 'DefaultClientWebSocketSession' type
    val frame = incoming.receive()
    when (frame) {
        is Frame.Text -> println(frame.readText())
        is Frame.Binary -> println(frame.readBytes())
    }
}

but what I need as reference, like this:

val someWsObject = httpClient.wss(
    method = HttpMethod.Get,
    host = "<http://echo.websocket.org|echo.websocket.org>",
    port = 8090,
)

someWsObject.connect()

val frame = someWsObject.incoming.receive()
    when (frame) {
        is Frame.Text -> println(frame.readText())
        is Frame.Binary -> println(frame.readBytes())
    }

Is this what you are looking for?

i just have a private var webSocketSession: DefaultClientWebSocketSession? = null and I do webSocketSession = this first thing inside my block

[edenman]

it’s janky API but it works fine

thanks!!

yes, these are viable alternatives but still overcomplicated

I'll stick with okhttp3 websockets until this is fixed

I ran into this as well, and used the HttpClient#webSocketSession method which returns a DefaultClientWebSocketSession. There's a close method on that which can be used to stop it, and I defined an extension method on DefaultClientWebSocketSession in my class to start/run the message handling loop.
