本文介绍了一个简易的控制台聊天程序，包括服务器端和客户端代码。该程序使用Winsock进行网络通信，能够实现基本的消息发送和接收功能。

今天在网上找到了个控制台聊天程序实例，感觉不错，稍微做些修改，以作收藏之用。

服务器端程序代码：

// 2009-06-28 #pragma comment(lib,"ws2_32.lib") #include<winsock2.h> #include<iostream> #include<string> using namespace std; string strCurMsg=""; void recvProc(SOCKET sockConnect) { char msgRcv[100]={0}; while(true) { if(SOCKET_ERROR==recv(sockConnect,msgRcv,sizeof(msgRcv),0)) { cout<<"/nHe is leaving"; return; } if(msgRcv[0]!='/0') { strCurMsg.erase(strCurMsg.end()-7,strCurMsg.end()); strCurMsg+="He said: "; strCurMsg+=msgRcv; strCurMsg+='/n'; strCurMsg+="input: "; system("cls"); cout<<strCurMsg; } } } int main(int argc, char* argv[]) { WORD wVersionRequested; WSADATA wsaData; int err; wVersionRequested = MAKEWORD( 1, 1 ); err = WSAStartup( wVersionRequested, &wsaData ); if ( err != 0 ) { return 1; } if ( LOBYTE( wsaData.wVersion ) != 1|| HIBYTE( wsaData.wVersion ) != 1) { WSACleanup( ); return 1; } SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP); sockaddr_in addrSrv; memset(&addrSrv,0,sizeof(addrSrv)); addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY); addrSrv.sin_family=AF_INET; addrSrv.sin_port=htons(5000); if(bind(sockSrv,(sockaddr*)&addrSrv,sizeof(sockaddr))==SOCKET_ERROR) { cout<<"bind error"<<endl; } if(listen(sockSrv,5)==SOCKET_ERROR) { cout<<"listen error"<<endl; } SOCKADDR_IN addrClient; int len=sizeof(sockaddr); while(true) { cout<<"Waiting ....."; SOCKET sockConnect=accept(sockSrv,(sockaddr*)&addrClient,&len); if(sockConnect==INVALID_SOCKET) { cout<<"invalid socket"<<endl; return 0; } else { cout<<"He is coming/n"; } CreateThread(NULL,0, (LPTHREAD_START_ROUTINE)recvProc,(void*)sockConnect, 0,NULL); while(true) { char buf[100]={0}; strCurMsg+="input: "; system("cls"); cout<<strCurMsg; cin.getline(buf,100); strCurMsg.erase(strCurMsg.end()-7,strCurMsg.end()); strCurMsg+="You said:"; strCurMsg+=buf; strCurMsg+='/n'; send(sockConnect,buf,sizeof(buf),0); } closesocket(sockConnect); } WSACleanup(); return 0; }

客户端程序代码：

// 2009-06-28 #pragma comment(lib,"ws2_32.lib") #include<winsock2.h> #include<iostream> #include<string> using namespace std; string strCurMsg=""; void recvProc(SOCKET sockClient) { char msgRcv[100]={0}; while(true) { if(SOCKET_ERROR==recv(sockClient,msgRcv,sizeof(msgRcv),0)) { cout<<"/nHe is leaving"; return; } if(msgRcv[0]!='/0') { strCurMsg.erase(strCurMsg.end()-7,strCurMsg.end()); strCurMsg+="He said: "; strCurMsg+=msgRcv; strCurMsg+='/n'; strCurMsg+="input: "; system("cls"); cout<<strCurMsg; } } } int main(int argc, char* argv[]) { WORD wVersionRequested; WSADATA wsaData; int err; wVersionRequested = MAKEWORD( 1, 1 ); err = WSAStartup( wVersionRequested, &wsaData ); if ( err != 0 ) { return 1; } if ( LOBYTE( wsaData.wVersion ) != 1|| HIBYTE( wsaData.wVersion ) != 1) { WSACleanup( ); return 1; } SOCKET sockClient=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP); SOCKADDR_IN addrSrv; addrSrv.sin_addr.S_un.S_addr=inet_addr("127.0.0.1"); addrSrv.sin_family=AF_INET; addrSrv.sin_port=htons(5000); if (connect(sockClient,(sockaddr*)&addrSrv,sizeof(sockaddr)) == SOCKET_ERROR) { cout<<"connected failed/n"; return 1; } else { cout<<"connect OK/n"; } CreateThread(NULL,0, (LPTHREAD_START_ROUTINE)recvProc,(void*)sockClient, 0,NULL); while(true) { char buf[100]={0}; strCurMsg+="input: "; system("cls"); cout<<strCurMsg; cin.getline(buf,100); strCurMsg.erase(strCurMsg.end()-7,strCurMsg.end()); strCurMsg+="You said:"; strCurMsg+=buf; strCurMsg+='/n'; send(sockClient,buf,sizeof(buf),0); } closesocket(sockClient); WSACleanup(); return 0; }

在此，向提供此代码结构的作者表示感谢~
