本文介绍了一种使用ActionScript 3连接MySQL数据库的方法，并提供了一个简单的包装类来简化操作流程。该方法通过ActionScript3MySqlDriver实现，支持基本的SQL语句如SELECT、INSERT和DELETE。

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:

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。
