C/S

socket还不是太熟悉，首先要链接库文件

下面是简单的测试代码，可以运行，已经测试过^^.

S:

?

#include <iostream>

#include <winsock2.h>

#pragma comment(lib,"ws2_32.lib")

 

int main()

{

    SOCKET serversock,clientsock;

    WSADATA  wsa;

    char buf[100];

    struct sockaddr_in serveraddr;

 

    WSAStartup(MAKEWORD(2,2),&wsa);     

 

    serversock=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);  //使用TCP协议

    serveraddr.sin_family=AF_INET;

    serveraddr.sin_port=htons(6666);

    serveraddr.sin_addr.S_un.S_addr=INADDR_ANY;  //自动获取本地IP地址

 

    bind(serversock,(struct sockaddr*)&serveraddr,sizeof(serveraddr));

    listen(serversock,1);

     

 

    clientsock=accept(serversock,NULL,NULL); //返回新的socket

    memset(buf,0,100);

    recv(clientsock,buf,100,0);      //接收客户端的信息

    strcat(buf,"  this is server");

    send(clientsock,buf,100,0);         //服务器发送信息

    closesocket(serversock);

    WSACleanup();                 //释放资源

    return 0;

}

 C:

?

#include <iostream>

#include <winsock2.h>

#pragma comment(lib,"ws2_32.lib")

 

using namespace std;

 

int main()

{

    SOCKET sockclient;

    struct sockaddr_in clientaddr;

    char buf[100]="I am a mouse";

    WSADATA wsa;

    sockclient=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);          //使用TCP协议

    clientaddr.sin_family=AF_INET;

    clientaddr.sin_port=htons(6666);

    clientaddr.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");

    connect(sockclient,(struct sockaddr*)&clientaddr,sizeof(clientaddr));        //链接服务器

 

    send(sockclient,buf,100,0);                    //发送信息

    memset(buf,0,100);

    recv(sockclient,buf,100,0);                    //从客户端接收信息

    cout<<"buf:"<<buf<<endl;

    closesocket(sockclient);
