首先,我必须通过OpenSSL连接到远程服务器,如前所述
here
bio = BIO_new_connect("www.tools.ietf.org:80");
if(bio == NULL)
{
/* Handle the failure */
}
if(BIO_do_connect(bio) <= 0)
{
/* Handle failed connection */
}
安全版本:
BIO * m_bio;
SSL_CTX * m_ctx;
SSL * m_ssl;
SSL_library_init();
m_ctx = SSL_CTX_new(SSLv23_client_method());
SSL_load_error_strings();
ERR_load_BIO_strings();
OpenSSL_add_all_algorithms();
SSL_CTX_set_default_verify_paths(m_ctx);
m_bio = BIO_new_ssl_connect(m_ctx);
BIO_get_ssl(m_bio, &m_ssl);
SSL_set_mode(m_ssl, SSL_MODE_AUTO_RETRY);
BIO_set_conn_hostname(m_bio, "www.tools.ietf.org:80");
if (BIO_do_connect(m_bio) <= 0)
{
printf("Error: %s\n", ERR_reason_error_string(ERR_get_error()));
throw std::runtime_error("FEEDREADER: Connection failed.");
}
if(SSL_get_verify_result(m_ssl) != X509_V_OK)
{
throw std::runtime_error("FEEDREADER: Verification failed.");
}
在哪里?
do_connect
失败,错误如下:
当我替换
www.tools.ietf.org
具有
http(s)://www.tools.ietf.org
但是主机名&dns对于不安全的版本很有效,所以有人能帮我解决这个问题吗?
