C ++ Socks5主机名解析

Question

我使用以下代码连接到localhost上运行的tor服务器。由于某些原因，此代码解析了ip并且仅提供IP地址。所以我无法连接到隐藏的服务，因为tor需要DNS名称进行连接。对于连接常规IP，所有工作都按预期工作，仅针对隐藏服务存在问题。

我做错了什么？有什么我想念的吗？我正在使用VisualStudio 2013。

非常感谢任何帮助!!

int fd = socket(AF_INET, SOCK_STREAM, 0);
if (fd < 0)
    return 1;
struct sockaddr_in destaddr;
destaddr.sin_addr.s_host = (unsigned char) "6esfckh37teglfi5.onion";
int dest_port = 19452;

struct sockaddr_in saddr;
saddr.sin_port = htons(9150);
saddr.sin_family = AF_INET;
saddr.sin_addr.s_addr = inet_addr("127.0.0.1");
int rv = connect(fd, (struct sockaddr *)&saddr, sizeof(saddr));
if (rv < SOCKET_ERROR)
    return 1;
char buf[256], *ptr;
ptr = buf;
PUT_BYTE(ptr++, 5);
PUT_BYTE(ptr++, 1);
PUT_BYTE(ptr++, 0x00);
send(fd, buf, ptr - buf, 0);
recv(fd, buf, 2, 0);
if ((buf[0] != 5) || buf[1] == 0xFF)
{
    exit(0);
}
ptr = buf;
PUT_BYTE(ptr++, 5);
PUT_BYTE(ptr++, 1);
PUT_BYTE(ptr++, 0);
PUT_BYTE(ptr++, 1);
memcpy(ptr, &destaddr.sin_addr.s_addr, sizeof(destaddr.sin_addr));
ptr += sizeof(destaddr.sin_addr);
PUT_BYTE(ptr++, dest_port >> 8);
PUT_BYTE(ptr++, dest_port & 0xFF);
send(fd, buf, ptr - buf, 0);
recv(fd, buf, 4, 0);
if (!buf[1] != 0x00)
{
    ptr = buf + 4;
    switch (buf[3]) {
    case 1:
        recv(fd, ptr, 4 + 2, 0);
        break;
    case 3:
        recv(fd, ptr, 1, 0);
        recv(fd, ptr + 1, *(unsigned char*)ptr + 2, 0);
        break;
    case 4:
        recv(fd, ptr, 16 + 2, 0);
        break;
    }
}

编辑：

我更正了我的代码并将addr位更改为3，仍然没有成功：

int dest_port = 19452;

    struct sockaddr_in saddr;
    saddr.sin_port = htons(9150);
    saddr.sin_family = AF_INET;
    saddr.sin_addr.s_addr = inet_addr("127.0.0.1");
    int rv = connect(fd, (struct sockaddr *)&saddr, sizeof(saddr));
    if (rv < SOCKET_ERROR)
        return 1;
    char buf[256], *ptr;
    ptr = buf;
    PUT_BYTE(ptr++, 5);
    PUT_BYTE(ptr++, 1);
    PUT_BYTE(ptr++, 0x00);
    send(fd, buf, ptr - buf, 0);
    recv(fd, buf, 2, 0);
    if ((buf[0] != 5) || buf[1] == 0xFF)
    {
        exit(0);
    }
    ptr = buf;
    PUT_BYTE(ptr++, 5);
    PUT_BYTE(ptr++, 1);
    PUT_BYTE(ptr++, 0);
    PUT_BYTE(ptr++, 3);
    //memcpy(ptr, &destaddr.sin_addr.s_addr, sizeof(destaddr.sin_addr));
    //ptr += sizeof(destaddr.sin_addr);
    memcpy(ptr, "22", 1);
    memcpy(ptr, "iszgnywrejvdg2nc.onion", sizeof("iszgnywrejvdg2nc.onion"));    
    PUT_BYTE(ptr++, dest_port >> 8);
    PUT_BYTE(ptr++, dest_port & 0xFF);
    send(fd, buf, ptr - buf, 0);
    recv(fd, buf, 4, 0);
    if (!buf[1] != 0x00)
    {
        ptr = buf + 4;
        switch (buf[3]) {
        case 1:
            recv(fd, ptr, 4 + 2, 0);
            break;
        case 3:
            recv(fd, ptr, 1, 0);
            recv(fd, ptr + 1, *(unsigned char*)ptr + 2, 0);
            break;
        case 4:
            recv(fd, ptr, 16 + 2, 0);
            break;
        }
    }
