Actionscripts 3 POST JSON with Content Header

Question

I'm trying to post JSON to server but code not working. I found some example to post JSON with Actionscripts 3 but i need to define content type in code. i post my test code here.

I tested url+header+body in firefox RESTClient and they working. [![enter image description here][1]][1] I'm sure URL is true and working in another places but here i got error "Error opening URL"

URL:"https://api.thinger.io/v2/users/***"

Content Header: "application/json"

Body: {"in":true}

var loader: URLLoader;

function ATN() {
    loader = new URLLoader();
    configureListeners(loader);

    var header: URLRequestHeader = new URLRequestHeader("Accept", "application/json");
    var request: URLRequest = new URLRequest("https://api.thinger.io/v2/users/***");
    request.data = new URLVariables("in:true");
    request.method = URLRequestMethod.POST;
    request.requestHeaders.push(header);
    try {
        loader.load(request);
    } catch (error: Error) {
        trace("Unable to load requested document.");
    }

Answer 1

The error is in parsing the string you are providing to the URLVariables constructor. URLVariables is only really for constructing name/value pairs. If you want to send JSON simply set the data property directly:

var postData:Object = { "in": true };
request.data = JSON.stringify( postData );
