使用MooTools在请求正文中POST JSON

Question

I'm trying to post JSON between URLs in my app. The receiving URL expects JSON in the body of the request and responds with JSON in the body of the request. The problem is I can't seem to send JSON in the body using Mootools Request.JSON. This is what I have:

// formObj is an object constructed from a form
var request = new Request.JSON({
    url: "/api/object.new",
    urlEncoded: false,
    onRequest: function(){
        // swap submit button with spinner
    },
    onComplete: function(jsonObj) {
        // work with returned JSON
    },
    body: JSON.encode(formObj)
});
request.setHeader("Content-Type", "application/json");
request.post();

The server returns a 500 error:

BadValueError: Property name is required

Which means that request.name is returning None which means that the server is not getting my JSON.

Using HTTPClient to paste the output of JSON.encode(formObj) into the body field produces the desired results.

Answer 1

body is not a valid mootools property for Request. use data: blah instead. as it stands, data is empty so no wonder you get nothing on the server side...
