I have read a lot about parsing JSON with Actionscript. Originally it was said to use this library. http://code.google.com/p/as3corelib/ but it seems Flash Player 11 has native support for it now.

My problem is that I cannot find examples or help that takes you from beginning to end of the process. Everything I have read seems to start in the middle. I have no real experience with JSON so this is a problem. I don’t even know how to point ActionScript to the JSON file it needs to read.

I have a project with a tight deadline that requires me to read twitter through JSON. I need to get the three most recent tweets, along with the user who posted it, their twitter name and the time those tweets were posted.

The back end to this is already set up I believe by the development team here, therefor my JSON files or XML just needs to be pointed to and then I need to display the values in the interface text boxes I have already designed and created.

Any help will be greatly appreciated…I do know that there are a lot of threads on here I just do not understand them as they all have some understanding of it to begin with.

    You need to:

    1. Load the data, whatever it is.

    2. Parse the data from a particular format.

    For this you would normally:

    1. Use URLLoader class to load any data. (Just go to the language reference and look into example of how to use this class).

    2. Use whatever parser to parse the particular format that you need. http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/JSON.html this is the reference to JSON API, it also shows usage examples. I’m not aware of these API being in production version of the player, still there might be quite a bit of FP 10.X players out there, so I’d have a fallback JSON parser, but I would recommend using this library: http://www.blooddy.by/en/crypto/ over as3corelib because it is faster. The built-in API are no different from those you would find in browser, so if you look up JSON JavaScript entries, the use should be in general similar to Flash.

    After you parse JSON format, you will end up with a number of objects of the following types: Object, Array, Boolean, Number, String. It has also literals to mean null and undefined. Basically, you will be working with native to Flash data structures, you only should take extra care because they will be dynamically constructed, meaning you may not make assumption about existence of parts of the data – you must always check the availability.
