请教用在线工具访问websocket一直报错1006是什么原因？

Question

在github下载的demo能用自带的js文件访问，但当用线上工具访问时1006

项目地址：https://github.com/luoyusoft/springboot-demo.git

主要代码：

@Slf4j
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic","/all");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/websocket").setAllowedOrigins("*").withSockJS();
    }

}



    @CrossOrigin
    @MessageMapping("/chat")
    public void messageHandling(RequestMessage requestMessage) throws Exception {
        String destination = "/topic/" + HtmlUtils.htmlEscape(requestMessage.getRoom());

        String sender = HtmlUtils.htmlEscape(requestMessage.getSender());  //htmlEscape  转换为HTML转义字符表示
        String type = HtmlUtils.htmlEscape(requestMessage.getType());
        String content = HtmlUtils.htmlEscape(requestMessage.getContent());
        ResponseMessage response = new ResponseMessage(sender, type, content);

        messagingTemplate.convertAndSend(destination, response);
    }


    @CrossOrigin
    @MessageMapping("/chatAll")
    public void messageHandlingAll(RequestMessage requestMessage) throws Exception {
        String destination = "/all";
        String sender = HtmlUtils.htmlEscape(requestMessage.getSender());  //htmlEscape  转换为HTML转义字符表示
        String type = HtmlUtils.htmlEscape(requestMessage.getType());
        String content = HtmlUtils.htmlEscape(requestMessage.getContent());
        ResponseMessage response = new ResponseMessage(sender, type, content);

        messagingTemplate.convertAndSend(destination, response);
    }
