我的node.js客户端应用程序连接到第三方Websocket API，用于使用ws npm包连续发送/接收数据。有时连接由服务器关闭，因为短暂的服务中断（至少我相信这是原因）并且我的应用程序需要重新建立连接。
我在这篇文章中得到了一个很好的解决方案，它适用于一些重新连接，但随后我的应用程序崩溃了： （用户Yury Fedorov Node-js: Not receiving events after websocket reconnect）：
const WS = require('ws');
var BFX = new WS('bfxs://api.uri.com/ws/2');
function createWebsocket() {
const websocket = new BFX().ws(2, opts);
websocket.on('open', /* code */);
websocket.open();
}
并在on('close')中调用它：
websocket.on('close', ()=>{
setTimeout(createWebsocket, 10000);
});
我得到的错误是：Error: read ECONNRESET
我安装了npm package longjohn以获得更长的堆栈跟踪，但我无法解释更长的堆栈跟踪：

- What is causing the crash?
- Can I catch the error somewhere and react
to it better?
- How can I debug this better?
- Thank you!
UPDATE:
user keja reminded me to add `websocket.on('error', (err) => console.log('error:', err));` to my listeners. The result is a similar but longer stack trace of the error message:

也许这可以指出你的方向是错误的。
