Key*_*uzi 5 sockets android websocket kotlin ktor
有没有办法使用 ktor WebSocket lib 检查 Android 设备上的连接状态?我想在 WebSocet 连接或断开连接时发出通知。这有什么好玩的吗?
这是我的代码:
try {
client = HttpClient() {
install(WebSockets) {
}
}
client.ws(
method = HttpMethod.Get,
host = "hostName", path = "/ws"
) {
send(Frame.Text("SampleText"))
for (frame in incoming) {
when (frame) {
checkFrame()
}
}
}
} catch (e: Exception) {
Log.i(TAG, "${e.message} Exception")

您可以检查是否收到关闭帧:
when (frame) {
is Frame.Text -> // Do text stuff here
is Frame.Close -> // Socket is closing/Closed
}

或者检查DefaultClientWebSocketSession是否有 closeReason:
if(webSocketSession?.closeReason != null) {
// Socket closed
}
