[AS2]Flash版本的Cookie类

利用Flash的SharedObject类的功能，来模拟Cookie的功能！

/** * @link http://www.klstudio.com * @author Kinglong * @usage flash player 7 * @version 0.1 */ class as2.util.Cookie { 	 	private var _time:Number; 	private var _name:String; 	private var _so:SharedObject; 	 	public function Cookie(name:String,time:Number){		 		_name = (name == undefined)?"klstudio":name; 		_time = (time == undefined)?36000:time; 		_so = SharedObject.getLocal(_name,"/"); 	} 	 	public function clearTimeOut():Void{ 		var obj:Object = _so.data.cookie; 		if(obj == undefined){ 			return; 		} 		for(var key in obj){ 			if(obj[key] == undefined || obj[key].time == undefined || isTimeOut(obj[key].time)){ 				delete obj[key]; 			} 		} 		_so.data.cookie = obj; 		_so.flush(); 	} 	private function isTimeOut(time:Number):Boolean{ 		var today:Date = new Date();		 		return time + _time * 1000 < today.getTime(); 	} 	 	public function getTime():Number{ 		return _time; 	}	 	public function getName():String{ 		return _name; 	} 	public function clear():Void{ 		_so.clear(); 	}	 	public function put(key:String,value:Object):Void{ 		var today:Date = new Date(); 		key = "key_"+key; 		value.time = today.getTime(); 		if(_so.data.cookie == undefined){ 			var obj:Object = {}; 			obj[key] = value; 			_so.data.cookie = obj; 		}else{ 			_so.data.cookie[key] = value; 		} 		_so.flush(); 	} 	public function remove(key:String):Void { 		if (contains(key)) { 			delete _so.data.cookie["key_" + key]; 			_so.flush(); 		} 	} 	public function get(key:String):Object{		 		return contains(key)?_so.data.cookie["key_"+key]:null; 	}	 	public function contains(key:String):Boolean{ 		key = "key_" + key;	 		return _so.data.cookie != undefined && _so.data.cookie[key] != undefined; 	} }
