My server does not receive the json data that is supposed to get sent across. IS there something I am doing incorrectly. My server gets the get request with no data.

var XMLHttpRequest = require('xhr2'); let getJSON = (url, callback) => {

let xhr = new XMLHttpRequest();
xhr.open('GET', url1, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.responseType = 'json';

xhr.onload = () => {

    let status = xhr.status;

    if (status == 200) {
        callback(null, xhr.response);
    } else {
        callback(status);
    }
};
data = JSON.stringify({"url":"myurl.com"});
xhr.send(data);

};

getJSON('http://localhost:8000', (err, data) => {

if (err != null) {
    console.error(err);
} else {

    console.log(data);
}

});
