Sending Json Form from Flash AS3 - json

Question

i am having one form accepting json post in Asp.net which i need to call from Flash As3...
i am using below code to do that. I have seen some post in which they say its working fine.
But i am encountering below Error
Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
Here is my code.
var messages:Array = new Array ();
messages.push({"From":fromemailTxt.text,"To": ToemailTxt.text,"Body": BodyText.text,"Subject":SubjectText.text});
var JsonObj:String = JSON.encode(messages);
trace(JsonObj);
var variables:URLVariables=new URLVariables(JsonObj);
RequestURL= srvStringURL;
var JSONLoader:URLLoader = new URLLoader();
JSONLoader.dataFormat=URLLoaderDataFormat.TEXT;
JSONLoader.addEventListener(IOErrorEvent.IO_ERROR, GetBookmarkURLError, false, 0, true);
JSONLoader.addEventListener(Event.COMPLETE, parseBookmarkURLResult, false, 0, true);
var hdr:URLRequestHeader = new URLRequestHeader("Content-type", "application/json");
var request:URLRequest = new URLRequest(RequestURL);
request.requestHeaders.push(hdr);
request.data=variables;
request.method = URLRequestMethod.POST;
try
{
JSONLoader.load(request);
}
catch (error:ArgumentError)
{
trace("An ArgumentError has occurred."+error.errorID.toString());
}
catch (error:SecurityError)
{
trace("A SecurityError has occurred.");
}
catch (error:Error)
{
trace("Unable to load requested document.");
}
Anybody have any idea on this??
Thanks

Answer 1

The error is, because you are passing incorrect string to URLVariables constructor. Do not use URLVariables. Instead pass data as string: request.data=JsonObj;

Below is the code I am using to consume REST Web service and pass json parameter to service it shows. Error #2032: Stream Error.
Andy idea what is going wrong
var ldr:URLLoader = new URLLoader();
ldr.dataFormat = URLLoaderDataFormat.TEXT;
var strData:String = "{\"gparam\": [ {\"productid\": \"" + productId + "\"},{\"message\": \"" + mesage + "\"},{\"googleappid\": \"" + googleappid + "\"},{\"senderid\": \"" + senderid + "\"},{\"appname\": \"" + appName + "\"},{\"userid\": \"" + userId + "\"},{\"receiverid\": \"" + receiverId + "\"} ]}";
var hdr:URLRequestHeader = new URLRequestHeader("Content-type", "application/json");
var req:URLRequest = new URLRequest("http://localhost/AndroidGCM/GCMNotification.svc/SendGCM");
req.requestHeaders.push(hdr);
req.method = URLRequestMethod.POST;
req.data = strData;
trace("data: " + req.data);
ldr.addEventListener(Event.COMPLETE,onComplete);
ldr.addEventListener(IOErrorEvent.IO_ERROR , onError);
ldr.addEventListener(SecurityErrorEvent.SECURITY_ERROR ,onSecurityErr);
ldr.load(req);
function onComplete(e:Event):void
{
trace("LOAD COMPLETE: " + ldr.data);
TextField(parMC.getChildByName("txtCheck")).appendText("\n LOAD COMPLETE: " + ldr.data);
}
function onSecurityErr(e:SecurityErrorEvent):void
{
trace("error: " + e.text );
}
function onError(e:IOErrorEvent):void
{
trace("error: " + e.toString());
}
