我正在一个AWS nodeJS实例上运行一个socket.io + EC2 + httpd应用程序。
在加载页面时,记录器提供以下信息:
GET / 200 2ms - 1.23kb
GET /javascripts/script.js 304 1ms
debug - served static content /socket.io.js
GET /stylesheets/style.css 304 1ms
GET /stylesheets/style.css 304 1ms

debug - client authorized

debug - setting request GET /socket.io/1/websocket/EgWLPeyO2uiCTSui01CP
debug - set heartbeat interval for client EgWLPeyO2uiCTSui01CP
warn - websocket connection invalid

debug - set close timeout for client EgWLPeyO2uiCTSui01CP
debug - cleared close timeout for client EgWLPeyO2uiCTSui01CP
debug - cleared heartbeat interval for client EgWLPeyO2uiCTSui01CP此时,事情将停止大约5秒,之后:
debug - setting request GET /socket.io/1/xhr-polling/EgWLPeyO2uiCTSui01CP?t=1376937523124
debug - setting poll timeout
debug - client authorized for

debug - set close timeout for client EgWLPeyO2uiCTSui01CP
debug - setting request GET /socket.io/1/xhr-polling/EgWLPeyO2uiCTSui01CP?t=1376937523490
debug - setting poll timeout
debug - discarding transport
debug - cleared close timeout for client EgWLPeyO2uiCTSui01CP在此之后,据我所知,事情开始正常工作,事件被触发和接收,没有延迟(如果事件在上面描述的5秒延迟之前被触发,则在延迟完成后才会被处理)。问题是如何消除5秒的延迟。
客户端JS如下所示:
window.onload = function () {
var socket = io.connect("http://xxx.us-west-2.compute.amazonaws.com", {resource: "/socket.io"});服务器端JS如下所示:
var express = require('express');
var app = express();
var io = require("socket.io").listen(app.listen(3000));我的httpd.conf文件如下所示:
ProxyPreserveHost On
ProxyPass / http://localhost:3000/
ProxyPassReverse / http://localhost:3000/
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
allow from all
</Location>如何避免初始延迟并建立与socket.io的健康连接?

我通过将允许的传输方法限制为“xhr-轮询”和“jsonp-轮询”来解决这个问题。我认为这是因为Apache/2.2.25不提供对其他文件的支持。
相关代码被添加到服务器端:
io.set("transports", ["xhr-polling", "jsonp-polling"]);https://stackoverflow.com/questions/18302507
