I'm trying to POST some JSON data using Adobe Flex but having some problems. I'm now getting the error message "A URL must be specified with useProxy set to false", even though I do have useProxy set to false.
Update : code below is now working.

I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:
var send_lv:LoadVars = new LoadVars();
send_lv.data = JSON.stringify({some json object});
var response_lv:LoadVars = new LoadVars();
response_lv.onData = function(rawdata) {
[code]....
In somepage.php, I can grab that JSON data using $_POST['data'].However, on this project, the developer of the web service requires the JSON content to be the BODY of the request (i.e., not a name/value pair). Is this possible with LoadVars?
I have to work with webservices in Actionscript. I found the following code that allows me to use JSON URLs that implement only the GET method. However, it doesn't work for POST methods (doesn't even enter the "onComplete" method). How can i "POST" JSON data using Actionscript 3.0?

I am trying to return results from my SQL database, using PHP to convert it into JSON, which is then read by Flex. Here is the parse error I receive -

Created an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData);

However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
Is it possible to "POST" JSON data in the body of a request with LoadVars? I understand LoadVars sends data as name>value pairs. How can I send the data in the body instead?

I have a pure ActionScript 3 problem, but the simplified test case I've prepared is in Flex 4 for better visibility (the source code is below): Since Flash Player 11 / AIR 3 support JSON natively, I've decided to move a multiplayer game, which used XML for communicating with server, to JSON. But I have a frustrating problem, that given two Objects like

I was wondering if someone could explain or point me in the direction of how to implement an API that uses JSON in ActionScript 3.0. What I specifically want to know is how would I grab specific information. The following is how I do it in XML but I don't know how I would do something similar in JSON as in getting the equivalent of an XML tag. For example with the twitter API I'd like to grab the text [URL]
[Code]....
api_result = '{"response":[{"uid":1969258,"first_name":"Walle","last_name":"Woo"}]}';
var myobj:Object = JSON.decode(api_result);
So, how I can get uid, first_name and last_name from "response" array?
Is there some library for flex, that will let me: define properties to fully exclude from serialization define classes to serialize without the property names (as if they were an array)

I'm using Flex 4 for building the communication to Arduino. There are three (3) main values coming from it (X,Y,Z). Here the Flex's code
newText.text = magnetic.readUTFBytes(magnetic.bytesAvailable);
d = JSON.decode(newText.text);
MNx = d["x"];
MNy = d["y"];
MNz = d["z"];
Is there any example or codes (in Flex) that can I create and save these values as a TXT file (data.txt). These values as a structure should be like below.

I'm using Flex 4. Have PHP backend and mysql database with one table consisting of multiple rows. I take the raw data from the result event and decode it using JSON. I then dump the data into an ArrayCollection that I use as my datagrid's data provider.
My question is how can I tell when someone inserts a new row into the mysql table so that I can automatically refresh my ArrayCollection, thus seamlessly updating my datagrid one element at a time? Right now, it's just a one time call and the connection is closed. If someone inserts a new row into the database my program doesn't recognize, unless I restart it. I'd like to auto-update the AC whenever a single new row is inserted into the mysql database. Is there a way I can "listen" for this change?

I have some shared code between an Adobe AIR App and an Adobe Flex App.
On one line of this code, the program must behave differently depending on if it is running within the Air runtime, or the Flex runtime.
How can I programmatically detect the difference?
Is it possible to call a web service from within Flash (using AS3)? Or is the best idea to put the flash movieclip in a Flex container and use the Flex Libraries?
To be clear, when I say within Flash, I mean within the Flash CS4, AS3 programming environment.
I'm using as3corelib to decode/encode JSON strings. In my little experiment I want to encode an object (UserInfo) to JSON string and decode it back to the object, however it seems to fail at the convertion point (the last line), why would that happen? how can I make it work?

I need to parse a large trace file (up to 200-300 MB) in a Flex application. I started using JSON instead of XML hoping to avoid these problems, but it did not help much. When the file is bigger than 50MB, JSON decoder can't handle it (I am using the as3corelib).
Try to split the file: I would really like to avoid this; I don't want to change the current format of the trace files and, in addition, it would be very uncomfortable to handle.Use a database: I was thinking of writing the trace into a SQLite database and then reading from there, but that would force me to modify the program that creates the trace file.
I am trying to set the json content type on httpservice to make REST service return the json data. When I add the content type in fiddler all works fine so the problem lays in flex application, not in the web-service. But the code below does not work and I get the xml data instead of json.
mxml:
<s:HTTPService id="service" method="POST" url="server.com" result="loaded(event)" fault="fault(event)" useProxy="false" resultFormat="text">
Actionscript:
public function loadAllSamples():void {
service.contentType = "application/json";
service.send('something');
}
I have done some searching around, and from what it looks like so far, there is no native way to parse JSON in Actionscript/Flex. XML is automagiaclly parsed and life is good. Why isn't JSON parsed this same way?
View 1 RepliesIn a very simple first AIR application (I'm using Flash Builder 4.5), I am trying to accomplish the following on my MacBook:
Read a local file (JSON format) into the AIR app. Parse through the file. Display some selected contents in a grid.
That's it.
I've found an example that does some simple JSON parsing in Flex, but the problem is that it loads the JSON source from a remote web site.
So do I need to load any file-specific libraries to make this work in AIR? Or can I simply refer to the file by using the Mac file-path? I just want the local file to be the JSON source. The parsing is already taken care of.
