ios - SocketRocket 导致 Node.js WebSocket 崩溃

Question

我写了一个简单的Node.js WebSocket chat server 。为了运行服务器，我将 foreman start 与仅包含以下行的 Procfile 结合使用:chat: npm start。

我还编写了一个使用 SocketRocket 的 iPhone 应用程序连接到上述服务器。在 applicationDidEnterBackground: 中，我在 webSocket 上调用 close。并且，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 | TypeError: Uncaught, unspecified "error" event.
chat.1 |     at TypeError (<anonymous>)

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

为什么会发生这种情况？还有，我该如何解决这个问题？

Answer 1

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 代码中查找导致此问题的原因，但目前它适用于
