socket网络编程-简单的收发消息的C/S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；
