How can i use ws with HttpsProxyAgent

[syter]

My project is create a websocket connection between my computer and a internet websocket server.
Now I want to use proxy.
I get some proxy IP from Internet. Such as: 'http://51.38.71.101:8080'.

Here is my code:

var WebSocket = require('ws');
var http = require("http");
var HttpProxyAgent = require('http-proxy-agent');
var HttpsProxyAgent = require('https-proxy-agent');
var urlUtil = require('url');

var reconnectInterval = 30 * 1000;
var reconnectTimeCount = 0;
var reconnectTotalCount = 10000;
var socket;
var proxy = 'http://51.38.71.101:8080';
var options = urlUtil.parse(proxy);
// var agent = new HttpsProxyAgent(options);
var agent = new HttpProxyAgent(options);

var connect = function(){
    try {
        console.log("========000000======");
        var url = 'ws://115.231.140.70';
        // socket = new WebSocket(url, { agent: agent });
        socket = new WebSocket(url);
        console.log("========1111======");
        socket.on('open', function() {
            console.log("=====connect====success====");
        });
        socket.on('message', function (data, flags) {
            console.log("=====received msg====");
        });
        socket.on('error', function(err) {
            console.log("************" + 'socket error'+ require('util').inspect(err));
        });
        socket.on('close', function() {
            console.log('socket close' + "===============reconnectTimeCount="+reconnectTimeCount);
            if (reconnectTimeCount <= reconnectTotalCount) {
                setTimeout(connect, reconnectInterval);
                reconnectTimeCount ++;
            }
        });
        console.log("========222222======");
    } catch (e) {
        console.log("========333333======");
    }   
    
};

connect();

When I use socket = new WebSocket(url);, my console log is:

SyterLius-MacBook-Air:app Syter$ node test.js 
========000000======
========1111======
========222222======
=====connect====success====

But when I use socket = new WebSocket(url, { agent: agent });, my console log is:

SyterLius-MacBook-Air:app Syter$ node test.js 
========000000======
========1111======
========222222======

I have test proxy IP in http.get way like documents said, it's no problem
So how can I do for it??

And my node version is v11.7.0
ws version is 7.0.1
https-proxy-agent version is 2.2.1
http-proxy-agent version is 2.1.0
