如何重定向Node.js + Express中的嵌套URL

Question

I'm tryin to do a module that redirect old urls to the new one on Node.JS + Express:

app.get('/category1', function (req, res){ res.redirect('/category2', 301) }) - works fine.

but when we're goin to /category1/subcategory it doesnt redirect to /category2/subcategory

How-to do this redirect rule like in apache's .htaccess:

RewriteRule ^category1/(.*)$ category2/$1 [R,NC,L]

eg

/category1 -> /category2

/category1/ -> /category2/

/category1/2/3/ -> /category2/2/3/

/category1/2/?a=1&b=2 -> /category2/2/?a=1&b=2

You can't build a route like the following?

app.get('/category/*', function(req, res){ 
    res.redirect('/category2/' + req.params[0], 301);
});

Edited for wildcard use case.

I'd suggest checking out expressjs.com's section on routing.
