How do I serve static file with express over cloudfoundry?

问题

How do I serve static files with express over cloudfoundry? I was trying to use the following code:

app.use(express.static(__dirname+'/www'));

but I am getting some bizarre exception when I am accessing the specific url:

TypeError: Object #<SendStream> has no method 'on'

I'v got this wrong too,and i found the answer; you can do this :

1st vmc delete yourapp

2nd vmc push yourapp --runtime node08

maybe you choose the wrong varsion of the Node runtime (node04,node06) at the 1st time you push the app to cloud ,and the server remember your choice.

That should work, if you create a template express application it is configured to serve static assets from the ./public folder. Make sure your configuration is something like this;

var app = express();

app.configure(function(){
  app.set('port', process.env.VCAP_APP_PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

If you would like, I can try and deploy your source myself and see if I can get it to work.
