有人使用Lacewing这个C++ socket库吗

Question

Lacewing::EventPump pump;
	Lacewing::Client* client = new Lacewing::Client(pump);
	client->Tag = this;
	client->onReceive(onReceiveEx);
	client->onConnect(onConnectEx);

	Lacewing::Address adb("127.0.0.1",12581,Lacewing::Address.HINT_IPv4);
	client->Connect(adb);
	pump.StartEventLoop();

代码如上，连接成功后onConnectEx会自动调用，但是当服务器发数据到client时，onReceiveEx却不有调用，貌似client没有接收到服务器发过来的数据。
