Question

我试图用袖珍材料收集闪电。 io,但并不总是在幼.污染中发生。

我看不出,如果任何人能够帮助,我会错做什么。

www.un.org/spanish/ecosoc 在服务器边:

var app = express.createServer(),
io = require( socket.io ).listen(app, {
    flashPolicyServer: true,
    transports: [ flashsocket ,  htmlfile ,  xhr-polling ,  jsonp-polling ]
});
app.listen(80);

www.un.org/spanish/ecosoc 在客户方面:

...
<script src="/socket.io/socket.io.js"></script>
...
            socket = io.connect();

            socket.on( connect , function(evt) {
                console.log(socket.socket.transport.name);

                onOpen(timeDifference(new Date(), earlierDate), socket.socket.transport.name);
                earlierDate = new Date();
                socket.on( disconnect , function(evt) {
                    onClose(evt);
                });
                socket.on( echo , function(msg) {
                    onEcho(msg);
                });
                socket.on( error , function(evt) {
                    onError(evt);
                });
            });

After that I checked that my browser chrome has flash enabled. I also checked that port 843 and 10843 are listening and responding :

<cross-domain-policy>
    <allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>

在服务器记录上,只有:

debug - client authorized

debug - setting request GET /socket.io/1/xhr-polling/14328044138726156?t=1333755740295

感谢你们的帮助

事实上,它发挥了作用!

Thanks to XHR, you lead me to more analyze and test so I could found by myself.

It works, but different as expected : When websocket is enabled on a browser, you cannot use flashsocket instead.

So even if you setup the server with : transports: [ flashsocket , htmlfile , xhr-polling , jsonp-polling ] your google chrome will never use flashsocket because it has websocket enabled and it falls back to xhr-polling. But Internet explorer which doesn t have websocket enabled will use flashsocket.

而且,我没有必要编定袖珍。如果没有网状,这种行为对我有利。

而且我认为,这一行为是空洞的,因为它防止在你不需要时装上沉重的卷宗。
