I'm making a small project in flex(flash builder 4.5) where the user can search for books. At the moment I can get books (im using google books api) but I receive it as JSON format.
I would like to get this in xml instead so i can show a few fields in a datagrid.
So far I've downloaded the as3corelib and linked that to my project. But I cant figure out how to Decode the JSON. JSON example
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="application1_creationCompleteHandler(event)"
>
<fx:Script>
<![CDATA[
import com.adobe.serialization.json.JSON;
import mx.controls.Text;
import mx.events.FlexEvent;
import mx.rpc.events.ResultEvent;
[Bindable] private var api_request:String;
import com.adobe.serialization.json.JSONDecoder;
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
// TODO Auto-generated method stub
btnSearch.addEventListener(MouseEvent.CLICK, Zoek);
}
protected function Zoek(event:MouseEvent):void
{
// TODO Auto-generated method stub
var api_url:String='https://www.googleapis.com/books/v1/volumes?q=';
var api_tag:String=search.text;
api_request= api_url + api_tag
GoogleBooks.send();
}
protected function GoogleBooks_resultHandler(event:ResultEvent):void
{
txtResult.text=event.result as String;
//JSONDecoder(txtResult.text);
}
]]>
</fx:Script>
<fx:Declarations>
<s:HTTPService id="GoogleBooks" url="{api_request}" resultFormat="text" result="GoogleBooks_resultHandler(event)" />
</fx:Declarations>
<s:Button x="175" y="40" label="Button" id="btnSearch"/>
<s:TextInput x="26" y="38" id="search"/>
<s:TextArea id="txtResult" x="32" y="112" width="539" height="312"/>
</s:WindowedApplication>
so my question is: How can i decode the JSON so i can see xml in my Textarea?
It depends on how you want to use the data. You could simply do
var data:Object = JSON.decode(jsonString);
or you could use the JSONDecoder class to do the same:
var decoder:JSONDecoder = new JSONDecoder(jsonString, jsonStringMatchesStandard);
var data:Object = decoder.getValue();
or you could use the JSONDecoder to decode the string token by token:
var decoder:JSONDecoder = new JSONDecoder(jsonString, jsonStringMatchesStandard);
var token:JSONToken = decoder.nextToken();
I would recommend looking in the comments of the sources the give good guidance on how to use the library.
