Socket.IO服务器挂起

Question

我是socket.io的新手.所以我的socket.io服务器sometimws崩溃给出以下错误

timers.js:103
        if (!process.listeners('uncaughtException').length) throw e;
                                                                  ^
Error: socket hang up
    at createHangUpError (http.js:1360:15)
    at ServerResponse.OutgoingMessage._writeRaw (http.js:507:26)
    at ServerResponse.OutgoingMessage._send (http.js:476:15)
    at ServerResponse.OutgoingMessage.write (http.js:749:16)
    at XHRPolling.doWrite (E:\sitesroot\0\node_modules\socket.io\lib\transports\
xhr-polling.js:67:17)
    at XHRPolling.HTTPPolling.write (E:\sitesroot\0\node_modules\socket.io\lib\t
ransports\http-polling.js:132:8)
    at XHRPolling.Transport.packet (E:\sitesroot\0\node_modules\socket.io\lib\tr
ansport.js:515:15)
    at Object.<anonymous> (E:\sitesroot\0\node_modules\socket.io\lib\transports\
http-polling.js:79:12)
    at Timer.list.ontimeout (timers.js:101:19)

它没有显示错误发生的位置或原因,因此非常确定它与我编写的代码无关.可能是运输的东西？我对此并不了解.任何关于如何阻止它崩溃的建议都将受到高度赞赏.谢谢

问题是@miktam说的.要解决此问题,您需要为代码添加错误侦听器.将此代码添加到您的应用程序:

//Error handler
process.on('uncaughtException', function (exception) {
  // handle or ignore error
  console.log(exception);
});

如果出现错误,它将调试它而不是崩溃它.我有完全相同的问题,这解决了它.
