Managing server JSON objects in Adobe AIR

I am facing an issue with a script that fetches objects from a remote server using an Ajax call. The server sends back objects in JSON format. However, while working on Adobe AIR, I encountered a restriction on utilizing eval() due to security concerns. As a result, I am able to receive responses from the remote server but unable to convert them into JavaScript objects. Is there any workaround for this challenge? I prefer using JSON as it can be implemented right away.

On a side note, I acknowledge the security risks associated with bypassing this limitation. However, considering my participation in a competition necessitating rapid app development, the software will only serve as a quick prototype and not intended for production purposes. Still, if there is a more efficient alternative available, I'd love to explore it.

Update:

Kudos to Theo and jsight for their valuable insights;

An important lesson learned today is the possibility of leveraging ActionScript libraries through the 

<script src="lib/myClasses.swf" type="application/x-shockwave-flash"></script>
tag supported by Adobe AIR. Refer to Theo's link for additional information!

Answer №1

If you're looking for a JSON parser written in JavaScript, check out this link to find the source code on GitHub (source code here). Another option is to use the as3corelib JSON parser from JavaScript, with instructions available here.

Answer №2

The latest version of AIR (v2.5) includes an updated WebKit with built-in JSON support, allowing for simplified handling through JSON.stringify() and JSON.parse().

Answer №3

Have you checked out the as3corelib library? It seems to offer an AS3 parser for JSON data without relying on eval, which is known for its security risks. Similar libraries exist for JavaScript as well, and they are often recommended for parsing JSON safely without using eval on potentially harmful data.

Answer №4

JSON stands for JavaScript Object Notation, making it a natural fit for anyone working with JavaScript. For guidance on creating JavaScript objects from JSON, check out these helpful resources:

If you opt for the Flex / AS3 path, consider starting with as3corelib, recommended by jsight.

Answer №5

Utilizing an iframe and sandbox bridge could potentially make this feasible. By running eval() on the downloaded code within the sandboxed iframe, it may be achievable.

This concept is highlighted in a passage from Adobe AIR 1.1 Doc's, stating "...it may be more convenient to run content in a sandboxed child frame so that the content can be run with no restrictions on eval()..."

Further insights on this topic can be found in the article titled: Building on AIR: Working with the Sandbox Bridges
