Question

I’m sending a json string to a REST server and receiving one in return, The flash code I’ve used is as follows

        var urlLoader : URLLoader = new URLLoader();
        urlLoader.dataFormat = URLLoaderDataFormat.TEXT;
        urlLoader.addEventListener(Event.COMPLETE, completeHandler);
        urlLoader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);

        var header1 : URLRequestHeader = new URLRequestHeader("Content-Type", "application/json");
        var header2 : URLRequestHeader = new URLRequestHeader("Accept", "application/json");
        var header3 : URLRequestHeader = new URLRequestHeader("pragma", "no-cache");

        var urlRequest : URLRequest = new URLRequest(url);
        urlRequest.requestHeaders.push(header1);
        urlRequest.requestHeaders.push(header2);
        urlRequest.requestHeaders.push(header3);

        urlRequest.data = session;
        urlRequest.contentType = "application/json";
        urlRequest.method = URLRequestMethod.POST;
        urlLoader.load(urlRequest);

When I don’t add the custom request headers to the request, my server receives the POST data correctly. When I add the custom headers, POST is empty. What could be causing this?

Though the data will be sent via POST, PHP won’t populate the $_POST global array because you’re using a Content-Type of application/json.

Try updating you Content-Type header to application/x-www-form-urlencoded:

var header1 : URLRequestHeader = new URLRequestHeader("Content-Type", "application/x-www-form-urlencoded");

And here as well, though you already set the header above:

urlRequest.contentType = "application/x-www-form-urlencoded";
