How to get dynamic website url?

Question

I'm trying to get data from the websocket of this page https://upbit.com/exchange?code=CRIX.UPBIT.KRW-BTC , but it looks like its website URL is dynamic and cannot be reused a second time, when I connect to it, it no longer sends me data, only the first connection is valid.

I have currently found a function in this JS file https://cdn.upbit.com/vender-bundle-03c1ef05e3ad23870adb.js ,

var a = this, c = o.addPath(t, "/websocket"); c = "https" === c.slice(0, 5) ? "wss" + c.slice(5) : "ws" + c.slice(4), this.url = c, this.ws = new u(this.url, [], n) 

There are thousands of functions with the same name n() , so I don't know what ideas? Thanks!

In this case, you do not need a dynamic URL. You can simply select one and use it as described in the answer below.
