Any clean code for response exception handling? -_-

[nschulzke]

If you're asking about ktor client, all the response exceptions extend ResponseException, so this code works fine if you don't need to distinguish between failure types:

try {
    // Your request here
} catch (e: ResponseException) {
    // Do something
}

Is that what you mean?

Could you please describe in what scenario do you want to handle exceptions?

Ktor StatusPages Plugin might be helpful

install(StatusPages) {
            exception<AuthenticationException> { cause ->
                call.respond(HttpStatusCode.Unauthorized)
            }
            exception<AuthorizationException> { cause ->
                call.respond(HttpStatusCode.Forbidden)
            }
            exception<ResponseException> { cause ->
                call.respond(mapOf("success" to false, "msg" to cause.message))
            }
            exception<Exception> { cause ->
                call.respond(mapOf("success" to false, "msg" to cause.message))
            }
            status(HttpStatusCode.Unauthorized) {
                call.respond(mapOf("success" to false, "msg" to "Your session expired. Please logout and login again."))
            }
        }
