Read external data

[Didier]

Finally, after several search and try, I am using the following code which is simple.

Here we try to read a json file with a node NN Json Get

The json file, called DT.json to read

{
“fruits”: [
{ “kiwis”: 3,
“mangues”: 4,
“pommes”: null
},
{ “panier”: true }
],
“legumes”: {
“patates”: “amandine”,
“poireaux”: false
},
“viandes”: [“poisson”,“poulet”,“boeuf”]
}

**The interesting part of the NNJsonGetNode code **

class NNJsonGetNode extends LogicNode {

.....
	override function run() {
		var value:String = inputs[1].get();
		
		var adr = "http://localhost:8040/Data/" + value;
		var http = new haxe.Http(adr);
		
		http.onData = function (data:String) {
				
			var res:{method:String,fruits:Array<Dynamic>} = haxe.Json.parse(data);
			trace("-------------------fruits-----------------------");
			for (n in res.fruits) {				
				trace(n);
			}

			var res1  = haxe.Json.parse(data);
			trace("-------------------legumes-----------------------");
			for (n in Reflect.fields(res1.legumes))
				trace(Reflect.field(res1.legumes, n));

			var res2:{method:String,viandes:Array<Dynamic>} = haxe.Json.parse(data);
			trace("------------------viandes------------------------");
			for (n in res2.viandes) {				
				trace(n);
			}
		}

		http.onError = function (error) {
		trace('error: $error');
		}

		http.request();
		
		super.run();
	}
....

tadaaa, in the console of the firefox browser, the result.
