从昨天开始，nginx 开始支持 websocket 连接，因此我试图让我的 nginx-nodejs-socket.io 应用程序在没有 harproxy 等的情况下工作（虽然运气不太好）。
我想要实现的是 nginx 仅将 websocket 连接请求发送到支持的服务器，或者更准确地说是 websocket 服务器，socket.io，同时 nginx 将提供 php 文件，以及包括 html 文件在内的所有静态内容.我根本不想 express 提供静态内容（如果可能的话）。
这是我的 nginx.conf

这是我在节点中的 server.js 文件
var express = require('express');
var app = express();
var port = 8080;
/* HTTP Server*/
server = require('http').createServer(app);
server.listen(port);
app.use(express.logger(':remote-addr - :method :url HTTP/:http-version :status :res[content-length] - :response-time ms'));
app.use(express.static(__dirname + '/html_public'));
app.use(express.favicon());
app.set('view engine', 'jade');
app.set('view options', { layout: false });
app.set('views', __dirname + '/views');
app.get('/', function(req, res){
res.render('index.html');
});
/*
* Web Sockets
*/
io = require('socket.io').listen(server),
io.configure('production', function(){
io.enable('browser client etag');
io.set('log level', 1);
io.set('transports', [ 'websocket', 'htmlfile', 'xhr-polling', 'jsonp-polling' ]);
});
console.log('Chat Server started with Node '+ process.version +', platform '+ process.platform + 'to port %d',port);
从我的客户，我尝试像这样连接：
socket = new io.connect('http://localhost/connection');
现在，问题是当我尝试正常连接时，键入 localhost，我在 chrome 控制台上看到：
**GET http://localhost/socket.io/socket.io.js 404 (Not Found)**，并且当在浏览器中键入时，http://localhost/connection我收到“Cannot GET /connection”，这告诉我 nginx 不能正常代理 websockets以我目前的配置。
提前感谢您的回答。
