server.cpp

#include <WINSOCK2.H>
#include <stdio.h>
#pragma comment(lib,"ws2_32.lib")
int main(int argc,char **argv)
{
    //创建套接字
    WORD myVersionRequest;

    addr.sin_family=AF_INET;
    addr.sin_addr.S_un.S_addr=htonl(INADDR_ANY);//ip地址
    addr.sin_port=htons(6000);//绑定端口

    bind(serSocket,(SOCKADDR*)&addr,sizeof(SOCKADDR));//绑定完成
    listen(serSocket,5);//其中第二个参数代表能够接收的最多的连接数

    //////////////////////////////////////////////////////////////////////////
    //开始进行监听

    SOCKADDR_IN clientsocket;
    int len=sizeof(SOCKADDR);
    while (1)

        char sendBuf[100];

        sprintf(sendBuf,"hello, %s !",inet_ntoa(clientsocket.sin_addr));//找对对应的IP并且将这行字打印到那里
        printf("Send:%s\n",sendBuf);

        char receiveBuf[100];//接收
        recv(serConn,receiveBuf,sizeof(receiveBuf),0);
        printf("recv:%s\n",receiveBuf);

        closesocket(serConn);//关闭
        WSACleanup();//释放资源的操作
        return 0;
    }
    return 1;
}
 

client.cpp

#include <WINSOCK2.H>
#include <stdio.h>
#pragma comment(lib,"ws2_32.lib")
int main(int argc,char **argv)
{
    int err;
    WORD versionRequired;
    WSADATA wsaData;
    versionRequired=MAKEWORD(1,1);
    err=WSAStartup(versionRequired,&wsaData);//协议库的版本信息
    if (!err)    {
        printf("客户端嵌套字已经打开!\n");
    }else{
        printf("ERROR:客户端的嵌套字打开失败!\n");
        return 1;//结束
    }
    SOCKET clientSocket=socket(AF_INET,SOCK_STREAM,0);

    SOCKADDR_IN clientsock_in;
    clientsock_in.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");
    clientsock_in.sin_family=AF_INET;
    clientsock_in.sin_port=htons(6000);

    //bind(clientSocket,(SOCKADDR*)&clientsock_in,strlen(SOCKADDR));//注意第三个参数
    //listen(clientSocket,5);
    connect(clientSocket,(SOCKADDR*)&clientsock_in,sizeof(SOCKADDR));//开始连接
    char receiveBuf[100];
    if(true){
        
        printf("Send:%s\n","hello,this is client");
        send(clientSocket,"hello,this is client",strlen("hello,this is client")+1,0);

        recv(clientSocket,receiveBuf,101,0);
        printf("Recv:%s\n",receiveBuf);

        closesocket(clientSocket);
        WSACleanup();
    }
    return 0;
}

编译运行:

call "C:\Program Files\Microsoft Visual Studio\VC98\Bin\VCVARS32.BAT"

cl server.cpp
cl client.cpp
start cmd /k server
start cmd /k client
cmd
