Use /company/:id* (note trailing asterisk).

Full example

var express = require('express')();

express.use(express.router);

express.get('/company/:id*', function(req, res, next) {
    res.json({
        id: req.params['id'],
        path: req.params[0]
    });    
});

express.listen(8080);

This works for /path and /path/foo on express 4, note the * before ?.
router.get('/path/:id*?', function(req, res, next) {
    res.render('page', { title: req.params.id });
});

Suppose you have this url: /api/readFile/c:/a/a.txt
If you want req.params.path to be c::
'/api/readFile/:path*
If you want req.params.path to be c:/a/a.txt:
'/api/readFile/:path([^/]*)'
