overruling the method before calling express router

app.js

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

app.use(function (req, res, next) {
    console.log(req);
    req.method = 'GET';
    next();
});

app.get('/', function (req, res, next) {
    res.send({foo: 1});
});

// listening
app.set('port', 3000);
app.listen(app.get('port'), function () {
    console.log("Server listening on port " +
        app.get('port') + " in " + app.get('env') + " mode");
});
