使用js XMLHttpRequest通过POST将对象传递给PHP

I need to send a simple object from my js script to php.

I created a js like this:

    var data = JSON.stringify({
        "name": "myname",
        "email": "foo@bar.com",
        "age": "15"
    });

    var http = new XMLHttpRequest();

        http.open('POST', url, true);
        http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');

        http.send(data);

        http.onreadystatechange = (function(e){
            if (http.readyState == 4 && http.status == 200) {
                console.log(JSON.parse(http.responseText));

            }
        });

Something does not work properly.

My PHP script just simply returns $_POST array back to js script.

echo json_encode($_POST);

And the response is weird: {"name": "myname","email": "foo@bar.com","age": "15"}: ""

It looks like server treats my whole object as a single parameter.

What can cause such behavior?
