一位IT民工的点点滴滴…… WEB前端、网页重构、AS3

package {
 import com.adobe.serialization.json.JSON;
 
 import flash.display.Sprite;
 import flash.events.Event;
 import flash.net.URLLoader;
 import flash.net.URLRequest;
 
 public class getJSON extends Sprite {
  public function getJSON() {
   var loader:URLLoader = new URLLoader();
 
   loader.load(new URLRequest( "http://127.0.0.1/json.php" ));//这里是你要获取JSON的路径
   loader.addEventListener(Event.COMPLETE, decodeJSON);
  }
  private function decodeJSON(evt:Event):void {
   var persons:Array = JSON.decode( URLLoader( evt.target ).data );
   //在这里，就可以通过操作数组来应用数据了，很方便
   for (var i=0; i<persons.length; i++) {
    trace( persons[i].name );
   }
  }
 }
}

 public class sendJSON extends Sprite {
  public function sendJSON() {
   var arr : Array = new Array({"name":"Hans","age":"32"},{"name":"John","age":"12"},{"name":"Zaki","age":"34"},{"name":"Dr. Cox","age":"88"});//这里是要发送的数据，可以直接写，也可以是由其他方法生成，不过要注意格式。
   sendjson( arr );
  }
  private function sendjson( a : Array ):void {
   var jsonString : String = JSON.encode(a);
 
   var urlVariables:URLVariables = new URLVariables();
   urlVariables.json = jsonString;
 
   var urlRequest:URLRequest = new URLRequest(http://127.0.0.1/json.php); //这里是接收数据的动态页。
   urlRequest.method = URLRequestMethod.POST;
   urlRequest.data = urlVariables;
 
   //其实到这已经结束了，下面的XML只是测试结果而已。
   var urlLoader:URLLoader = new URLLoader();
   urlLoader.addEventListener(Event.COMPLETE, onURLLoaderCompleteEvent);
   urlLoader.load(urlRequest);
  }
  private function onURLLoaderCompleteEvent( evt : Event ):void {
   var xml:XML = new XML(evt.target.data);
   trace(xml);
  }
 }
}

用XML表示如下：
<?xml version="1.0" encoding="utf-8"?>
　　<user>
　　<name>张三 </name>
　　<password>123456</password>
　　<department>技术部</department>
　　<sex>男</sex>
　　<age>30</age>
　　</user>
对于这样一个XML来说，如果数据量大了的确让人头昏眼花，也不好处理，但是如果我们转化成下面这种形式的话：
<?xml version="1.0" encoding="utf-8"?>
　　<user>
            <people name="张三" password="123456" depattment="技术部" sex="男" age="30" />
　　</user>
再跟相应该的JSON来比较：
{"name":"张三","password":"123456","department":"技术部","sex":"男","age":"30"}
也不会相差太多咯。

var serverJSON:String = '{ "programmers":{ "firstName": "Brett", "lastName":
"McLaughlin", "email": "brett@newInstance.com" }, "firstName": "Jason", 
"lastName":"Hunter", "email": "jason@servlets.com" },  "firstName": 
"Elliotte", "lastName":"Harold", "email": "elharo@macfaq.com" }],
"authors": "firstName": "Isaac", "lastName": "Asimov", "genre": 
"science fiction" }, "firstName": "Tad", "lastName": "Williams", "genre": 
"fantasy" }, "firstName": "Frank", "lastName": "Peretti", "genre": 
"christian fiction" }],"musicians":  "firstName": "Eric", "lastName": 
"Clapton", "instrument": "guitar" },{ "firstName": "Sergei", "lastName": 
"Rachmaninoff", "instrument": "piano" }]}'
var s:Object = JSON.decode(serverJSON);
//开始使用
trace(s.programmers[0].firstName);//输出：Brett

import json.*;
var myObject:Object = new Object();
myObject.ab = "adfsdf";
myObject.cd = Math.random();
trace(JSON.encode( myObject ));
//输出：{"ab":"adfsdf","cd":0.0599129400216043}
这样就可以给服务器了。
