javascript - Node.js WebSocket 错误 : read ECONNRESET after some reconnects

Question

我的 node.js 客户端应用连接到第三方 Websocket API，使用 ws npm 包连续发送/接收数据。有时由于短暂的服务中断(至少我相信这是原因)，服务器关闭了连接，我的应用程序需要重新建立连接。

我在这篇文章中找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: (Node-js: Not receiving events after websocket reconnect 用户 Yury Fedorov):

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 包 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:

websocket.on('error', (err) => console.log('error:', err));

也许这可以为您指出错误的方向。
