Difficulty accessing Google Search API with Flex
- by CM
Hi -
I am trying to get the number of incoming links to a page through the Google Search API.
It is not working (just returning Null)
Here is the code
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init();" width="320" height="480" backgroundGradientColors="115115" backgroundGradientAlphas=".2" backgroundAlpha=".2" dropShadowEnabled="false">
<mx:Script>

import mx.controls.Alert;
public function loadFile4(urlLink:String):void
{
var request:URLRequest = new URLRequest(urlLink);
var urlLoad:URLLoader = new URLLoader();
urlLoad.addEventListener(Event.COMPLETE, fileLoaded4);
urlLoad.load(request);
}
private function fileLoaded4(event:Event):void
{
var jObj:Object = JParser.decode(event.target.data); //Decode JSON from text file here.
var jStr:String = JParser.encode(jObj);
if(jStr != null && jStr != "")
{
var LinkTemp:String = jObj.estimatedResultCount;
txtLinks.text = "Google Links " + LinkTemp;
trace(event.target.data);
}
}
/********************************************************************/
private function LinkLookup():void
{
loadFile4("http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=link:twitter.com/" + NameSearch.text);
}

<mx:TextInput x="17" y="86" id="NameSearch" text="cnnbrk" width="229" height="30" fontSize="16" fontWeight="bold" cornerRadius="10" shadowDirection="center" shadowDistance="5"/>
<mx:Button x="253" y="85" label="Find" id="GoSearch" click="LinkLookup()" height="31"/>
<mx:Label text="Links" id="txtLinks" width="233" textAlign="left" color="#FFFFFF" fontSize="14" height="21"/>
</mx:Application>
Sorry for the ugly format.
I added a trace(event.target.data); and updated the code above.
This is the result -

So the data return from the query is correct, and the difficulty lies in accessing the "estimatedResultCount" near the end of the JSON data.
Any help would be greatly appreciated!
