我写了一个简单的Node.js WebSocket 聊天服务器。要运行服务器，我正在使用foreman start仅Procfile包含以下行的 a：chat: npm start。

我还编写了一个使用SocketRocket连接到上述服务器的 iPhone 应用程序。在，applicationDidEnterBackground:我打电话close。webSocket而且，在applicationWillEnterForeground:中，我重新创建webSocket并调用open.

进入后台或前台时，iPhone 应用程序似乎使服务器崩溃并出现以下错误：

chat.1 | events.js:74
chat.1 |         throw TypeError('Uncaught, unspecified "error" event.');
chat.1 |               ^

chat.1 | npm ERR! weird error 8
chat.1 | npm ERR! not ok code 0

为什么会这样？而且，我该如何解决？

我昨天遇到了同样的错误，并且能够通过附加“错误”事件处理程序在 Node.Js 端修复它

wss.on('connection', function(connection) {
  connection.on('error', function(reason, code) {
    console.log('socket error: reason ' + reason + ', code ' + code);
  });
}

我将尝试在 SocketRocket 代码中找到导致该问题的原因，但现在它适用于
