如何使用Ktor BoundDatagramSocket监听传入的udp流量

Question

我正在将ktor用于kotlin / native应用程序。目前，我正在android方面进行测试，因此我在viewmodel中直接添加了一些代码。该应用程序需要监听传入的udp数据报，但似乎什么也没收到。我在执行过程中做错了什么？

我在测试时如何监听传入的数据：

viewModelScope.launch(Dispatchers.IO) {
            aSocket(ActorSelectorManager(Dispatchers.IO)).udp()
                .bind(InetSocketAddress("localhost", 40779))
                .use { udpSocket ->
                    Log.d("hereUDP", udpSocket.localAddress.toString())
                    try {
                        while (!udpSocket.isClosed) {
                            val datagram = udpSocket.receive()
                            Log.d("hereUDP", "received")
                            val line = datagram.packet.readText()
                            Log.d("hereUDP", line)

                            if (line.toLowerCase() == "q")
                                udpSocket.close()
                        }
                        Log.d("hereUDP", "closed")
                    } catch (e:Throwable){
                        Log.d("hereUDP", "something went wrong", e)
                        udpSocket.close()
                    }
                }
        }

我实际上想要开始工作的代码：

coroutineScope {
            launch(Dispatchers.IO + socket!!.socketContext) {
                socket?.incoming
                    ?.consumeEach {
                        val data = it.packet.readBytes()
                        val address = it.address as InetSocketAddress
                        listener?.onReceive(data, HostEndpoint(address.hostName))
                    }
            }
        }
