Use ExpressJS to Get URL and POST Parameters

GET

// grab the packages we need
var express = require('express');
var app = express();
var port = process.env.PORT || 8080;

// routes will go here

// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);
http://example.com/api/users?id=4&token=sdfa3&geo=us
// routes will go here
app.get('/api/users', function(req, res) {
  var user_id = req.param('id');
  var token = req.param('token');
  var geo = req.param('geo');  

  res.send(user_id + ' ' + token + ' ' + geo);
});

POST

npm install body-parser --save
var bodyParser = require('body-parser');
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies

// POST http://localhost:8080/api/users
// parameters sent with 
app.post('/api/users', function(req, res) {
    var user_id = req.body.id;
    var token = req.body.token;
    var geo = req.body.geo;

    res.send(user_id + ' ' + token + ' ' + geo);

Passing multiple POST parameters to Web API Controller Methods

C# :

[HttpPost]
public string PostAlbum(JObject jsonData)
{
    dynamic json = jsonData;
    JObject jalbum = json.Album;
    JObject juser = json.User;
    string token = json.UserToken;

    var album = jalbum.ToObject<Album>();
    var user = juser.ToObject<User>();

    return String.Format("{0} {1} {2}", album.AlbumName, user.Name, token);
}

JavaScript :

var album = {
    AlbumName: "PowerAge",
    Entered: "1/1/1977"
}
var user = {
    Name: "Rick"
}
var userToken = "sekkritt";


$.ajax(
{
    url: "samples/PostAlbum",
    type: "POST",
    contentType: "application/json",
    data: JSON.stringify({ Album: album, User: user, UserToken: userToken }),
     success: function (result) {
        alert(result);
    }
