IE和Socket.io兼容性

问题描述

我在此处创建了一些聊天示例: http ://psitsmike.com/2011/09/node-js-and-socket-io-chat-tutorial/

I make some chat example like here: http://psitsmike.com/2011/09/node-js-and-socket-io-chat-tutorial/

当我使用Chrome和Firefox时，所有功能都像魅力一样.使用IE9或Opera时，某些socket.io事件不会触发(例如，断开连接)或触发得太晚，并且数据接收太慢.

When I use Chrome and Firefox everything works like a charm. With IE9 or Opera some socket.io events are not firing (e.g. disconnect) or firing too late, and data receiving is too slow.

我使用npm方法安装了node.js和socket.io模块.

I installed node.js and socket.io module with the npm method.

请帮助.

推荐答案

Socket.IO与websockets一起使用效果最佳.在2012年之前，大多数浏览器不支持websocket(源 ).

Socket.IO works best with websockets. Prior to 2012, most browsers did not support websockets (source).

使用这样的浏览器，socket.io会使用各种轮询方法，但是这些方法可能会导致您遇到问题，例如数据速率低和事件延迟(延迟1-2分钟触发).为此，您应该尝试启用闪存插槽.

With such browsers, socket.io falls back to various polling methods, but those may lead to problems you are experiencing, such as low data rate and delayed events (firing 1-2 minutes late). To remedy, this you should try to enable flash sockets.

 io.set('transports', [
     'websocket'
   , 'flashsocket'
   , 'htmlfile'
   , 'xhr-polling'
   , 'jsonp-polling'
 ]);

另外，请确保客户端可以访问闪存策略端口(默认值为10843).

Also, make sure the flash policy port (default 10843) is reachable from the client.
