Try <a href="https://github.com/nodejitsu/node-http-proxy" rel="nofollow">node-http-proxy</a>

It allows you to send http or websocket requests through a proxy.

<pre><code>var http = require('http'), 
httpProxy = require('http-proxy');
//
// Create a basic proxy server in one line of code...
//
// This listens on port 8000 for incoming HTTP requests 
// and proxies them to port 9000
httpProxy.createServer(9000, 'localhost').listen(8000);

//
// ...and a simple http server to show us our request back.
//
http.createServer(function (req, res) { 
 res.writeHead(200, { 'Content-Type': 'text/plain' });
 res.write('request successfully proxied!' + '\n' + JSON.stringify(req.headers, true, 2));
 res.end();
}).listen(9000);
</code></pre>

blocks|key|1696451|text|大多数网络代理还不支持websockets。最好的解决方法是通过指定wss://+(websocket安全协议)来使用加密：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1696452|wss://ws.pusherapp.com:[port]/app/[key]|code-block|syntax|javascript|1696453|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Most web proxies don't support websockets yet. The best workaround is to use encryption by specifying wss:// (websocket secure protocol):

<pre><code>wss://ws.pusherapp.com:[port]/app/[key]
</code></pre>

blocks|key|2691950|text|为websockets使用代理应该与https连接的工作方式大致相同；您应该使用CONNECT方法。至少HTTP和HTML5都是这么说的。因此，如果您的代理实现了连接，那么您就可以走了。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2691951|entityMap|0|LINK|mutability|MUTABLE|url|http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.9|1|http://www.websocket.org/aboutwebsocket.html^0|1G|4|0|1L|5|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

Using a proxy for websockets should work roughly the same as for https connections; you should use the CONNECT method. At least that's what both the <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.9" rel="nofollow">HTTP</a> and <a href="http://www.websocket.org/aboutwebsocket.html" rel="nofollow">HTML5</a> specs say. So if your proxy implements CONNECT, you're good to go.

Generalizing that would be the question... how to make websockets to go through a proxy in node.js?

In my particular case I'm using pusher.com with the <a href="https://github.com/abhishiv/pusher-node-client" rel="noreferrer">node.js client library</a> they recommend. Looking inside the code I would like to know some hints on what I should change in order to make this library to work with a proxy... you can take a look in the code <a href="https://github.com/abhishiv/pusher-node-client/blob/master/lib/pusher-node-client.js#L146-147" rel="noreferrer">here</a>

Maybe I should somehow replace or modified the <a href="https://github.com/abhishiv/pusher-node-client/blob/master/lib/pusher-node-client.js#L8" rel="noreferrer">websockets module</a> that is being used by the library?

EDIT

Thanks for your answers/comments! A couple of things to take into consideration (excuse me if I'm wrong with some/all of them, just learning):

<ul>
<li>I don't want to create a proxy server. I just want to use an existent proxy server within my company in order to proxified my websockets requests (particularly pusher.com)</li>
<li>Just to let you know, if I use a proxifier like the one for windows <a href="http://www.proxifier.com/" rel="noreferrer">Proxifier</a> and I set up the rule to inspect for all connections to port 443 to go through the proxy server proxy-my.coporate.com:1080 (type SOCKS5) it works like a charm.</li>
<li>But I don't want to go this way. I want to programatically configuring this proxy server within my node js code (even if that involved to modified the pusher library I mentioned)</li>
<li>I know how to do this for HTTP using <a href="https://github.com/mikeal/request" rel="noreferrer">Request module</a> (look for the section that mentions how to use a proxy).
<ul>
<li>I want a similarly thing for websockets.</li>
</ul></li>
</ul>

概括了，这是一个问题.如何使websockets通过node.js中的代理？在我的特殊情况下，----我使用的是pusher.com和他们推荐的。在代码内部，我想知道一些提示，说明我应该修改什么，以便使这个库与代理一起工作.您可以查看代码也许我应该以某种方式替换或修改库所使用的？编辑谢谢你的回答/评论！有几件事情需要考...
