Question about ktor-client. How to know there is response boby or not, before calling HttpResponse.body()?

[Aleksei Tirman [JB]]

You need to read at least one byte to determine it:

val channel = client.get<ByteReadChannel>("<http://example.com/>")
val hasBody = try {
    channel.readByte()
    true
} catch (_: ClosedReceiveChannelException) {
    false
}

Could you please explain why do you need it?
