c# - 如何忽略 ssl_client_socket_impl.cc(1061)] 在 selenium c# ChromeDriver 中握手失败

Question

我已经添加了

 ChromeOptions options = new ChromeOptions();
 options.AddArgument("--ignore-certificate-errors-spki-list");
 options.AddArgument("--ignore-ssl-errors");
 options.AddArgument("test-type");
 options.AddArguments("-incognito");
 options.AddArgument("no-sandbox");
 options.AddArgument("--start-maximized");
 driver = new ChromeDriver(options);

但仍然得到:

ssl_client_socket_impl.cc(1061)] handshake failed error 

如何从控制台抑制这个错误？

Answer 1

这个错误信息...

[ERROR:ssl_client_socket_openssl.cc(855)] handshake failed; returned -1, SSL error code 1, net_error -2

...意味着 ChromeDriver 和 Chrome 浏览器 之间的握手失败在某个时候失败了。

根本原因

此错误是由于 net::SSLClientSocketImpl::DoHandshake 产生的和 net::SSLClientSocketImpl在 ssl_client_socket_impl.ccnet::SSLClientSocketImpl::DoHandshake 中实现如下:

int SSLClientSocketImpl::DoHandshake() {
  crypto::OpenSSLErrStackTracer err_tracer(FROM_HERE);
  int rv = SSL_do_handshake(ssl_.get());
  int net_error = OK;
  if (rv <= 0) {
    int ssl_error = SSL_get_error(ssl_.get(), rv);
    if (ssl_error == SSL_ERROR_WANT_CHANNEL_ID_LOOKUP) {
      // The server supports channel ID. Stop to look one up before returning to
      // the handshake.
      next_handshake_state_ = STATE_CHANNEL_ID_LOOKUP;
      return OK;
    }
    if (ssl_error == SSL_ERROR_WANT_X509_LOOKUP &&
    !ssl_config_.send_client_cert) {
      return ERR_SSL_CLIENT_AUTH_CERT_NEEDED;
    }
    if (ssl_error == SSL_ERROR_WANT_PRIVATE_KEY_OPERATION) {
      DCHECK(ssl_config_.client_private_key);
      DCHECK_NE(kSSLClientSocketNoPendingResult, signature_result_);
      next_handshake_state_ = STATE_HANDSHAKE;
      return ERR_IO_PENDING;
    }
    OpenSSLErrorInfo error_info;
    net_error = MapLastOpenSSLError(ssl_error, err_tracer, &error_info);
    if (net_error == ERR_IO_PENDING) {
      // If not done, stay in this state
      next_handshake_state_ = STATE_HANDSHAKE;
      return ERR_IO_PENDING;
    }
    LOG(ERROR) << "handshake failed; returned " << rv << ", SSL error code "
           << ssl_error << ", net_error " << net_error;
    net_log_.AddEvent(
    NetLogEventType::SSL_HANDSHAKE_ERROR,
    CreateNetLogOpenSSLErrorCallback(net_error, ssl_error, error_info));
  }
  next_handshake_state_ = STATE_HANDSHAKE_COMPLETE;
  return net_error;
}

根据 ERROR:ssl_client_socket_openssl.cc handshake failed主要问题是 ChromeDriver 与 Chrome 中的 SSL 页面 握手时握手 失败>。尽管 Chromium 团队通过 net_unittests、content_tests 和 browser_tests 对 SSL 握手 进行了测试但并不详尽。一些用例依赖于上游测试而被排除在外。

结论

此错误不会中断您的测试套件的执行，您可以暂时忽略此问题，直到它被修复由 Chromium 团队。
