1、服务端发送和传输数据详解服务器发送数据时盥要知道客户端的IP地址和端11号TCP服务器端服务器发送数据时需要知道客户端的IP地址和端口号发送数据SocketSender::SocketSender(constString&_strlp,int_iPort){mstrip=strlp;//ip地址m_iPort=_iPort;//端口m_socket=INVALID_SOCKET;//定义一个无效的socketintibl,ib2,ib3,ib4,ib5,ib6;//6个IP地址swscanf_s(m_strlp.GetCString()
2、,_T("%d.%d.%d.%d.%d.%d"),&ibl,&ib2,&ib3,&ib4,&ib5,&ib6);memset(&m_addr,0,sizeof(maddr));maddr.sinfam订y=AFINET;m_addr.sin_port二htons((u_short)_iPort);(UCHAR)ibl(UCHAR)ib2(UCHAR)ib3(UCHAR)ib4m_addr.sin_addr.S_un.S_un_b.s_blmaddr.sinaddr.Sun.S_un_b.s_b2m_addr.sin_sddr.S_un.

4、ocket==INVALID_SOCKET){//如果是无效socket抛出异常THROWEXCEPTION(ExceptionSocketError());}//将参数m_socket连至参数m_addr指定的网络地址。建立连接(服务端socket,指向包含IP和端口号的扌旨针，m_3ddr的长度，与bind()参数一样)连接成功是返回0if(connect(m_sockct,(sockaddr*)&m_addr,sizeof(m_addr))!=0){THROW_EXCEPT1ON(ExceptionSocketError0);}S
5、ocketSender::^SocketSender(){join();//首先判断是否为无效的socket,有效时才可以进行关闭辻(m_socket匚INVAL1D_SOCKET){//关闭socket,成功关闭返四0if(closesocket(m_socket)!二0)THROWEXCEPTION(ExceptionSocketError());//清理成功返回0intiError=WSACleanupO;if(iError!=0)THROW_EXCEPTION(ExceptionWSAClcanup(iError))；}}//发
