Use stompjs and sockjs, in vue, etc., urgent

import SockJS from "sockjs-client";
import Stomp from" stompjs";
connect () {

// 
var socket = new SockJS("http://192.168.6.67:8081/endpoint"); 
var stompClient = Stomp.over(socket);
stompClient.connect({}, (frame) => {
    stompClient.subscribe("/user/39/queue/getResponse", function(respnose){
        console.log(2222)
        console.log(respnose);
    });
})

}
tune this.connect ();

in mounted

I don"t know if the things on my front end are wrong. I can use one-to-many ("/ topic/getResponse"), but not one-to-one ("/ user/39/queue/getResponse"). Please give me some advice

.

I don"t know if it"s my problem or the background problem.
