Simple example of using 2-legged OAuth in Node.js (requires node-oauth)

gistfile1.js

var express = require('express');
var oauth   = require('oauth');
var app     = express.createServer();
var key     = "[api-key]";
var secret  = "[api-secret]";
var request = new oauth.OAuth(null, null, key, secret, '1.0', null, 'HMAC-SHA1');

app.get('/api-request', function(req, res){
    request.get(
        "http://127.0.0.1:8000/api/1.0/data.json",
        null,
        null,
        function (err, data, result) {
            if (err) {
                res.send("Error getting data : " + sys.inspect(error), 500);
            } else {  
                res.send(data)
            } 
    });
});

app.listen(parseInt(process.env.PORT || 88));
