我遵循了“Heroku上的Node.js入门”指南[2]中的建议.当我在本地使用节点index.js运行应用程序时,我能够访问http:// localhost:8080 / index.jade上的应用程序,但是,当我尝试在http:// immonow上的heroku上访问它时. herokuapp.com:8080/index.jade它会给我一个ERR_CONNECTION_REFUSED HTTP错误代码.
我如何部署我的应用:
> git commit -am“进行了更改”//提交更改
> git push origin master //推送到git
> heroku创建//创建heroku应用程序
> git push heroku master //推送到heroku
> heroku ps:scale web = 1 //开始工作
我的node.js服务器:
#!/usr/bin/env node
var http = require('http')
, jade = require('jade')
, static = require('node-static')
, jadeRe = /\.jade$/
, path = process.argv.slice(2)[0]
, fileServer = new static.Server(path || '.')
http.createServer(function (req, res) {
if (req.url.match(jadeRe)) {
res.writeHead(200, {'Content-Type': 'text/html'})
res.end(jade.renderFile('.' + req.url, {
filename: '.' + req.url.replace(jadeRe, '')
}))
} else {
req.addListener('end', function () {
fileServer.serve(req, res)
}).resume()
}
}).listen(8080)
任何帮助,将不胜感激.

由于我无法使用http包让它工作,我决定使用express代替.至于港口,我必须按照以下方式进行var port = process.env.PORT || 3000; app.listen(port);
为了让它发挥作用[1].
这是我的全功能服务器:
/**
* Module dependencies.
*/
var express = require('express');
// Path to our public directory
var pub = __dirname + '/public';
// setup middleware
var app = express();
app.use(express.static(pub));
app.use("/css", express.static(__dirname + '/css'));
app.use("/font", express.static(__dirname + '/font'));
app.use("/img", express.static(__dirname + '/img'));
app.use("/js", express.static(__dirname + '/js'));
app.use("/video", express.static(__dirname + '/video'));
// Set our default template engine to "jade"
// which prevents the need for extensions
// (although you can still mix and match)
app.set('view engine', 'jade');
app.get('/', function(req, res){
res.render('index');
});
app.get('/*', function(req, res){
console.log(req.url.replace("/",""));
res.render(req.url.replace("/",""));
});
// change this to a better error handler in your code
// sending stacktrace to users in production is not good
app.use(function(err, req, res, next) {
res.send(err.stack);
});
/* istanbul ignore next */
if (!module.parent) {
var port = process.env.PORT || 3000;
app.listen(port);
console.log('Express started on port 3000');
}
