Send and Get payload in express JS

Now I send data to express server as query param. But, I instead send the data to express server as payload. How do I send payload data to express server? And how do I get the payload data from express server? Can anyone clear my doubts?

Here is my code, 

// http request code

var http=new XMLHttpRequest();
http.open('post','localhost:9090/putData');
http.onload=function(){
    if (this.status >=200 && this.status <300){
        console.log(this.response);
    }
};
var payload = {
    data: 'Something'
}
http.send(payload);

// server.js

app.use(bodyParser.json({limit: '50mb'}));

app.use('/putData', function(req, res){
     console.log(req.body); // empty object printed
})

What's wrong in my code.

You'll need to reference 'body' from the request object. Depending on the type, you can deserialize it with a parser. I use the npm package 'body-parser' to deserialize my objects to json. Set up the body parser in the express middleware as shown below

app.use(bodyparser.json({limit: '50mb'}));

Then you can use the req.body object in your following requests`

app.get('getBody', function(req, res){
   console.log(req.body);
   res.status(200);
});`
