Android 创建简单的Socket服务器

GlobalScope.launch(Dispatchers.IO) {
            val serverSocket = ServerSocket(8600)
            LogUtils.e("服务器即将启动：${DeviceUtils.getIPAddress(AppContext)}")
            while (true) {
                try {
                    serverSocket.accept().apply {
                        LogUtils.e("收到了客户端连接:${inetAddress}")
                        getInputStream().use { isr ->
                            PrintWriter(getOutputStream()).use { pw ->
                                val buffer = ByteArray(1024 * 1024)
                                var len: Int = -1
                                while (isConnected && (((isr.read(buffer)
                                        .also { len = it }) != -1))
                                ) {
                                    val result = String(buffer, 0, len)
                                    LogUtils.e("客户端收到了消息：$result")
                                    pw.write("服务端发送了消息：$result")
                                    pw.flush()

                    LogUtils.e("服务器运行失败")
                }
            }
