A c ++ http get code

The Code is as follows (from: http://bbs.csdn.net/topics/320012075 ):

#include <winsock2.h>#include<windows.h>#include<stdio.h>#pragma comment(lib, "ws2_32.lib") int main(int argc, char* argv[]){    char server_name[256]= "www.163.com";     WSADATA wsaData;    struct sockaddr_in srv_addr;     if (WSAStartup(0x202,&wsaData) == SOCKET_ERROR) {        WSACleanup();        return -1;    }     SOCKET cli_sock=socket(PF_INET,SOCK_STREAM,0);    if (cli_sock==INVALID_SOCKET)        return -1;     // connect to server     srv_addr.sin_family = AF_INET;    LPHOSTENT lphost = gethostbyname(server_name);    if (lphost != NULL)        srv_addr.sin_addr.s_addr = ((LPIN_ADDR)lphost->h_addr)->s_addr;    srv_addr.sin_port= ntohs(80);    if (connect(cli_sock,(LPSOCKADDR)&srv_addr,sizeof(srv_addr))==SOCKET_ERROR){        return -1;    }     char sz[]="GET / HTTP/1.1\r\nHost:www.163.com\r\n\r\n";    int retval = send(cli_sock,sz,sizeof(sz)-1,0);    if( SOCKET_ERROR == retval )        return 0;    char buffer[1024]={0};    while( SOCKET_ERROR != retval ){        retval = recv(cli_sock ,buffer,1000,0);        printf("%s\n",buffer);    }    closesocket(cli_sock);    return 0;}

Run in vc6.

The format of the http get request message.

For example, convert the following URL into a GET request message:
Http: // 192.168.11.240/list. php? Username = xyq@yahoo.com

Convert:

Get (Space)/list. php? Username = xyq@yahoo.com (Space) HTTP/1.1 (\ r \ n)
HOST: 192.168.11.240 (\ r \ n)
Accept: */* (\ r \ n)
User-Agent: MSIE 6.00 (\ r \ n)
Connection: keep-alive (\ r \ n)
