我正在托管apache和node.js服务器以及代理到节点服务器的apache服务器。我的框架是express.js，我正在使用amCharts.I有超时代理设置为600.当我打开我的网站时，我只得到静态内容而不是amCharts的动态内容。
这是我的服务器端代码：
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var fs = require('fs');
var data = '';
var app = express();
var server = app.listen(3000);
var io = require('socket.io').listen(server);
// all environments
//app.set('port', process.env.PORT || 3000);
//app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
io.sockets.on('connection', function (socket) {
setInterval(function(){
var file = __dirname + '/config.json';
fs.readFile(file, 'utf8', function (err, data) {
if (err) {
console.log('Error: ' + err);
return;
}
data = JSON.parse(data);
// You can save those values somewhere or just log them to the console
console.dir(data);
socket.emit('news', { hello: data});
});
}, 5000);
});
app.get('/', function (req, res){
res.render('map1.html');
});
app.set('views', __dirname + '/views');
app.engine('html', require('ejs').renderFile);
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
console.log("Express server listening on port 3000");
控制台上的错误是：

我的apache conf文件配置是

解决了问题。在虚拟主机配置文件中，我刚刚添加了：
ProxyPass http://localhost:3000/
ProxyPassReverse http://localhost:3000/
/在代理传递结束时它起作用了。
