socket网络编程-简单的收发消息的CS模式(含代码)

1.代码

客户端:

void Client::init() { WSADATA wsa; WSAStartup(0x0202, &wsa); client = socket(AF_INET, SOCK_STREAM, 0); SOCKADDR_IN addr; addr.sin_family = AF_INET; addr.sin_port = htons(c_port); addr.sin_addr.S_un.S_addr = inet_addr(c_ip); int ret = connect(client, (sockaddr*)&addr, sizeof(addr)); if (ret == 0) { sendMessage(); } else cout << "connect ret:" << ret << endl; } void Client::sendMessage() { cout << "*****服务端连接成功*****" << endl; string str; while (cin >> str) { int ret = send(client, (char *)str.c_str(), str.length(), 0); if (ret != str.length()) cout << "发送失败" << endl; } }

服务端:

void Server::init() { WSADATA wsa; int ret =WSAStartup(0x0202, &wsa); m_server = socket(AF_INET, SOCK_STREAM, 0); std::cout << "m_server:" << m_server << std::endl; SOCKADDR_IN addr; addr.sin_family = AF_INET; addr.sin_port = htons(c_port); addr.sin_addr.S_un.S_addr = inet_addr(c_ip); int bindRet = ::bind(m_server, (sockaddr*)&addr, sizeof(addr)); listen(m_server, 5); } void Server::run() { while (true) { SOCKADDR_IN m_client; int len = sizeof(SOCKADDR_IN); std::cout << "等待客户端连接..." << std::endl; SOCKET client = accept(m_server, (sockaddr*)&m_client, &len); if(client <= 0) continue; std::cout <<"客户端:"<<client<< "连接成功" << std::endl; m_mapClient.insert(std::pair<SOCKET, int>(client, heartCount)); std::thread t_read(&Server::readMessage, this, client); t_read.detach(); } }

2.功能

主要是实现客户端发送消息 服务端接收消息; 需要修改端口号 ip的时候需要手动去项目的common文件里面去修改常量的值 没有对TCP数据粘包问题进行解决； 下载代码 ： https://github.com/dreamisdream/C-/tree/master/socket vs2015直接可以运行;
