cocos2dx3.x利用sokcet创建客户端和服务端(一）

Socke基类：

包括Socket的初始化,主要是windows上，在android上就不需要了

如果平台为windows，则需要初始化

SocketBase::SocketBase(){_bInitSuccess = false;#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)WORD wVersionRequested;wVersionRequested = MAKEWORD(2, 0);WSADATA wsaData;int nRet = WSAStartup(wVersionRequested, &wsaData);if (nRet != 0) {fprintf(stderr, "Initilize Error!\n");return;}_bInitSuccess = true;#endif }

当然析构时也要释放资源

SocketBase::~SocketBase(){#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)if (_bInitSuccess){WSACleanup();}#endif }

因为windows的socket()返回的socket句柄为SOCKET(UINT_PTR)

与android的socket()返回的socket句柄int, 类型不一样，所以都定义为HSocket

对于服务端和客户端都有关闭连接，所以基类就实现共同的。

void SocketBase::closeConnect(HSocket socket){#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)close(socket);#elif (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)closesocket(socket);#endif}

当执行socket()出错时，windows返回SOCKET_ERROR, android 返回<0，

所以实现error()

bool SocketBase::error(HSocket socket){#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)return socket == SOCKET_ERROR;#elif (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)return socket < 0;#endif}
