AS3连接MYSQL数据库

最近由于制作任务编辑器，需要连接到数据库中进行一些任务数据的操作，而我们存放任务数据的数据库中MYSQL，所以就找了一下AS3接连MYSQL数据库的资料。

找到一个好东西：ActionScript 3 MySql Driver，用SVN的童鞋可以直接checkout: 

http://assql.googlecode.com/svn/trunk/

 

为了使用简单，我做了一个简单的包装类(包含一个数据结构)：

package com.easily.ds

{

	public class DataBaseData

	{

		public var host:String;

		public var port:int;

		public var username:String;

		public var password:String;

		public var database:String;

	}

}

package com.easily.util

{

	import com.easily.ds.DataBaseData;

	import com.maclema.mysql.Connection;

	import com.maclema.mysql.Field;

	import com.maclema.mysql.MySqlResponse;

	import com.maclema.mysql.MySqlToken;

	import com.maclema.mysql.ResultSet;

	import com.maclema.mysql.Statement;

	

	import flash.events.Event;

	import flash.events.EventDispatcher;

	

	import mx.rpc.AsyncResponder;



	/**

	 * @author Easily

	 */

	public class DataBase extends EventDispatcher

	{

		private var mDataBase:DataBaseData;

		private var mConnection:Connection;

		

		public function DataBase(database:DataBaseData)

		{

			mDataBase = database;

		}

		

		public function connect():void

		{

			mConnection = new Connection(mDataBase.host, mDataBase.port, 

				mDataBase.username, mDataBase.password, mDataBase.database);

			mConnection.addEventListener(Event.CONNECT, onConnected);

			

			mConnection.connect();

			

			function onConnected(event:Event):void

			{

				mConnection.removeEventListener(Event.CONNECT, onConnected);

				

				dispatchEvent(event);

			}

		}

		

		public function disconnect():void

		{

			mConnection.disconnect();

		}

		

		public function select(sql:String, completeHandler:Function, errorHandler:Function = null):void

		{

			var st:Statement = mConnection.createStatement();

			var token:MySqlToken = st.executeQuery(sql);

			var responder:AsyncResponder = new AsyncResponder(resultHandler, faultHandler, token);

			token.addResponder(responder);

			

			function resultHandler(result:Object/*ResultSet*/, token:Object/*MySqlToken*/):void

			{

				var data:Array = [];

				

				if (result is ResultSet)

				{

					var fieldList:Array = result.getColumns();

					while (result.next())

					{

						var item:Object = {};

						for each (var field:Field in fieldList)

						{

							item[field.getName()] = result.getString(field.getName());

						}

						data.push(item);

					}

				}

				

				completeHandler(data);

			}

			

			function faultHandler(info:Object, token:Object):void

			{

				if (errorHandler == null) return;

				

				errorHandler();

			}

		}

		

		public function insert(sql:String, completeHandler:Function, errorHandler:Function = null):void

		{

			var st:Statement = mConnection.createStatement();

			var token:MySqlToken = st.executeQuery(sql);

			var responder:AsyncResponder = new AsyncResponder(resultHandler, faultHandler, token);

			token.addResponder(responder);

			

			function resultHandler(result:Object/*MySqlResponse*/, token:Object/*MySqlToken*/):void

			{

				completeHandler(result.insertID);

			}

			

			function faultHandler(info:Object, token:Object):void

			{

				if (errorHandler == null) return;

				

				errorHandler();

			}

		}

		

		public function remove(sql:String, completeHandler:Function, errorHandler:Function = null):void

		{

			var st:Statement = mConnection.createStatement();

			var token:MySqlToken = st.executeQuery(sql);

			var responder:AsyncResponder = new AsyncResponder(resultHandler, faultHandler, token);

			token.addResponder(responder);

			

			function resultHandler(result:Object/*MySqlResponse*/, token:Object/*MySqlToken*/):void

			{

				completeHandler();

			}

			

			function faultHandler(info:Object, token:Object):void

			{

				if (errorHandler == null) return;

				

				errorHandler();

			}

		}

	}

}

其中有3个方法，select,insert,remove，分别对应了SQL语句中的select,insert,delete

用法很简单，先连接：

var databaseData:DataBaseData = new DataBaseData();		

databaseData.host = "127.0.0.1";

databaseData.database = "game";

databaseData.password = "123456";

databaseData.port = 3306;

databaseData.username = "root";



var dataBase:DataBase = new DataBase(databaseData);

dataBase.addEventListener(Event.CONNECT, onConnected);

dataBase.connect();



function onConnected(event:Event):void

{

	dataBase.removeEventListener(Event.CONNECT, onConnected);

	

	dispatchEvent(new Event(Event.COMPLETE));

}

如果不需要用了可以先断开连接：

dataBase.disconnect();

下面是select语句：

var sql:String = "select id,name from `npc`";

dataBase.select(sql, endQuery);



function endQuery(data:Array):void

{

	var npcList:Array=  [];

	for each (var item:Object in data)

	{

		var npc:Object = {id:item.id, name:item.name};

		

		npcList.push(npc);

	}	

}

insert语句用法会返回一个insertID，也就是插入的那条数据的ID。
