scoket connect 返回值为-1，求助

[低头路过]

WORD wVersionRequested;
WSADATA wsaData;
wVersionRequested=MAKEWORD(2,2);
WSAStartup(wVersionRequested,&wsaData);

SOCKET sockfd;
if ((sockfd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) == -1)
{
////DebugMsg("Socket Error: %s", strerror(errno));
return -1;
}

struct sockaddr_in server_addr;
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(80);
server_addr.sin_addr.s_addr = inet_addr("http://login.taobao.com");



if (connect(sockfd, (struct sockaddr *) (&server_addr), sizeof(struct sockaddr)) == -1)
{
return -1;
}

请教。。。
