我的程序在接受到代理(sock5)发回的“5 0”后，
发送sock5req2，但recv不到代理的返回信息，为何？
谢谢！
struct sock5req2
{
char VER;
char CMD;
char RSV;
char ATYP;
unsigned long DSTADDR;
unsigned short DSTPORT;
};
struct sock5ans2
{
char VER;
char REP;
char RSV;
char ATYP;
unsigned long BNDADDR;
unsigned short BNDPORT;
};
int main()
{
SOCKET smtp = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
//...sock5req1成功发送，代理返回5 0
struct sock5req2 *req2 = (struct sock5req2*)SendBuf;
req2->VER = 5;
req2->CMD = 1;
req2->RSV = 0;
req2->ATYP = 1;
req2->DSTADDR = inet_addr("220.181.12.11");//smtp.163.com 220.181.12.11
req2->DSTPORT = htons(25); // IPPORT_SMTP
nRet = send(smtp,SendBuf,sizeof(req2),0);
if(nRet == SOCKET_ERROR)
{
send_error(smtp);
return 1;
}
struct sock5ans2 *ans2 = (struct sock5ans2*)RecvBuf;
memset(RecvBuf,0,1024);
nRet = recv(smtp,RecvBuf,1024,0); //-*******recv 总是不成功********为何？
if(nRet == 0 || nRet == SOCKET_ERROR)
{
recv_error(smtp);
return 1;
}
cout<<ans2->VER<<" "<<ans2->REP<<" "<<ans2->ATYP<<endl;
in_addr server;
server.S_un.S_addr = ntohl(ans2->BNDADDR);
cout<<inet_ntoa(server)<<":"<<ntohs(ans2->BNDPORT)<<endl;
//...
}
