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。
扩张阅读:
ActionScript简称“AS”——动作脚本,是遵循 ECMAscript第四版 的 Adobe Flash Player 运行时环境的编程语言。它在 Flash 内容和应用程序中实现交互性、数据处理以及其他功能。 ActionScript是Flash的脚本语言,与JavaScript相似,ActionScript是一种编程语言,新出的AS3.0使用OOP(面对对象编程),增加更强的报错能力,指定类型也更明确。
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。
