跟官方的例子一样，可直接拷贝官方的例子运行，唯一的区别是安装的依赖由 futu-api 改为 node-futu-api

import ftWebsocket from "futu-api";
import beautify from "js-beautify";

function QotGetSecuritySnapshot() {
  let [addr, port, enable_ssl, key] = [

    33333,
    false,
    "xxx", // TODO 这里需替换为自己的websocket秘钥
  ];
  let websocket = new ftWebsocket();

  //关闭行情连接，连接不再使用之后，要关闭，否则占用不必要资源
  //同时OpenD也限制了最多128条连接
  //也可以一个页面或者一个项目维护一条连接，这里范例请求一次创建一条连接
  setTimeout(() => {
    websocket.stop();
    console.log("stop");
  }, 5000); // 5秒后断开
}
