Express.js：将默认的public / images文件夹更改为另一个目录（Express.js文件夹之外）

Question

In Express.js, I would like to keep my images/videos outside the Express.js project folder, meaning NOT in public/images. For instance, right now my media is in the Express.js project folder:

/home/myName/Project/public/images

And I would like my images/videos to be in

/home/myName/allMyMedia

My app.configure() function right now looks like this:

app.configure(function(){
app.set('port', process.env.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(expressValidator);
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(require('less-middleware')({ src: __dirname + '/public' }));
app.use(express.static(path.join(__dirname, 'public')));
});

I tried to change the '/public' to '../public' but that did not work. I also played a little bit around with the other path declarations for public, but up to know I could not figure out how to fix this. Any help would be appreciated.

If you want to serve some requests from your media folder and others from your public folder, invoke static twice as shown in https://github.com/visionmedia/express/blob/master/examples/static-files/index.js (has good comments)

var express = require('../..');
var app = express();

app.use(express.logger('dev'));
app.use(express.static(__dirname + '/public'));
app.use(express.static('/home/myName/allMyMedia/'));
app.use(app.router);

app.listen(3000);
// GET /images/foo.jpg will first check ./public/images/foo.jpg,
// then /home/myName/allMyMedia/images/foo.jpg,
// then it will attempt to match a routing function to '/images/foo.jpg'
// As usual, as soon as something sends a response, no further functions are called.
// Reorder the app.use stack to change this order.
