Socket.io code 200 Error during WebSocket handshake

Question

I am using socket.io with nodejs and an apache server over it. I am getting a code 200 as response, I know I must get

Answer 1

I use springboot 2 + stomp. In my case ,the reason is in WebSocketConfig,must remove .withSockJS.

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/ws").setAllowedOrigins("*")
                .addInterceptors(new HandshakeInterceptor())

                //--> important must remove,or 200 error.
                //.withSockJS()

                ;
    }
