我写了一个简单的Node.js WebSocket chat server。要运行服务器,我使用的foreman start
Procfile
仅包含以下行:chat: npm start
。
我还写了一个使用SocketRocket连接上述服务器的iPhone应用程序。在applicationDidEnterBackground:
,我在close
上致电webSocket
。并且,在applicationWillEnterForeground:
中,我重新创建webSocket
并致电open
。
当进入后台或前台时,iPhone应用程序似乎使服务器崩溃并出现错误:
chat.1 | events.js:74
chat.1 | throw TypeError('Uncaught, unspecified "error" event.');
chat.1 | ^
chat.1 | TypeError: Uncaught, unspecified "error" event.

为什么会这样?而且,我该如何解决它?
答案 0 :(得分:3)
我昨天遇到了同样的错误,并且能够通过附加'error'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,但现在可以使用
