okex websockets возвращает неожиданный ответ

0 голосов
/ 19 февраля 2020

Упоминается код узла, который я использую. Поскольку я использую okex websocket v3 с функциями глубины, ответ, который я получаю, не ожидается. Помогите мне получить фактические значения. 

const ws = require('ws')
exports.socketokex = function(req, res){
  var soc = new ws("wss://real.okex.com:8443/ws/v3")
  var msg = JSON.stringify({"op": "subscribe", "args": ["spot/depth5:ETH-USDT"]})

    soc.onopen = () => {
      console.log("opened")
      soc.send(msg)
    };

    soc.onmessage = e => {
      var value = e.data;
      console.log(e)
    };
}
