Ignore request for AuthorizationListener

[windery]

Question

I want to pass Authentication http header to my netty-socketio server(2.0.8), and do my auth logic in AuthorizationListener.

However I found an OPTIONS request without the Authentication header but trigger the AuthorizationListener. The OPTIONS request got an 401 error and client connet failed.

Is is possible to add more information of the request to let me know which is the OPTIONS request and I can ignore it manuely.

Environment

test util

Socket.IO Test Client (v0.7.2)

client config

 {
          "extraHeaders":  {
                    "Authorization":  "Bearer test"
          }
}

server config

    @Bean
    public SocketIOServer socketIOServer() {
        com.corundumstudio.socketio.Configuration config = new com.corundumstudio.socketio.Configuration();
        config.setHostname("0.0.0.0");
        config.setPort(port);
        config.setOrigin("*");
        config.setAllowHeaders("Authorization");
        config.setAuthorizationListener(handshakeData -> {
            System.out.println(new ObjectMapper().valueToTree(handshakeData));
            HttpHeaders headers = handshakeData.getHttpHeaders();
            for (Map.Entry<String, String> header : headers) {
                System.out.println(header.getKey() + ":" + header.getValue());
            }
            String authorization = headers.get("Authorization");
            if (StringUtils.hasText(authorization)) {
                return AuthorizationResult.SUCCESSFUL_AUTHORIZATION;
            }

            return AuthorizationResult.FAILED_AUTHORIZATION;
        });
        return new SocketIOServer(config);
    }
