如果我的服务器运行在8000端口,请说:
var s = http.createServer();
s.on('request', function(request, response) {
response.writeHeader(200);
response.end();
});
s.listen(8000);
var w = new WebSocketServer({
server: s
});
然后我希望将端口8000上收到的消息转发到端口9000:
w.on('connection', function(ws) {
var remote = null;
ws.on('message', function(data) {
remote = new WebSocket('ws://127.0.0.1:9000');
remote.on('open', function() {
remote.send(data);
});
});
ws.on('close', function() {
if (remote) {
return remote.destroy();
}
});
return ws.on('error', function() {
if (remote) {
return remote.destroy();
}
});
});
可悲的是,这种实施似乎并不奏效。什么是正确的方法呢?

这样做的正确方法是什么?
我会使用node-http-proxy,这将抽象出代理ws请求的细节:
var proxy = new httpProxy.createProxyServer({
target: {
host: 'localhost',
port: 9000
}
});
s.on('request', function(request, response) {
proxy.web(request, response);
});
s.on('upgrade', function (req, socket, head) {
proxy.ws(req, socket, head);
});
