This article mainly introduces "how to connect AS3 to MySQL database". In daily operation, I believe many people have doubts about how to connect AS3 to MySQL database. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to connect AS3 to MySQL database". Next, please follow the editor to study!

Find a good thing: ActionScript3MySqlDriver, you can checkout directly with SVN's children's shoes:

To make http://assql.googlecode.com/svn/trunk/ easy to use, I made a simple wrapper class (containing a data structure):

Packagecom.easily.ds {publicclassDataBaseData {publicvarhost:String;publicvarport:int;publicvarusername:String;publicvarpassword:String;publicvardatabase:String;}}

Packagecom.easily.util {importcom.easily.ds.DataBaseData;importcom.maclema.mysql.Connection;importcom.maclema.mysql.Field;importcom.maclema.mysql.MySqlResponse;importcom.maclema.mysql.MySqlToken;importcom.maclema.mysql.ResultSet;importcom.maclema.mysql.Statement;importflash.events.Event;importflash.events.EventDispatcher;importmx.rpc.AsyncResponder;/***@authorEasily*/publicclassDataBaseextendsEventDispatcher {privatevarmDataBase:DataBaseData;privatevarmConnection:Connection;publicfunctionDataBase (database:DataBaseData) {mDataBase=database } publicfunctionconnect (): void {mConnection=newConnection (mDataBase.host,mDataBase.port,mDataBase.username,mDataBase.password,mDataBase.database); mConnection.addEventListener (Event.CONNECT,onConnected); mConnection.connect (); functiononConnected (event:Event): void {mConnection.removeEventListener (Event.CONNECT,onConnected); dispatchEvent (event);}} publicfunctiondisconnect (): void {mConnection.disconnect ();} publicfunctionselect (sql:String,completeHandler:Function,errorHandler:Function=null): void {varst:Statement=mConnection.createStatement (); vartoken:MySqlToken=st.executeQuery (sql); varresponder:AsyncResponder=newAsyncResponder (resultHandler,faultHandler,token) Token.addResponder (responder); functionresultHandler (result:Object/*ResultSet*/,token:Object/*MySqlToken*/): void {vardata:Array= []; if (resultisResultSet) {varfieldList:Array=result.getColumns (); while (result.next ()) {varitem:Object= {}; foreach (varfield:FieldinfieldList) {item [field.getName ()] = result.getString (field.getName ());} data.push (item);}} completeHandler (data);} functionfaultHandler (info:Object,token:Object): void {if (errorHandler==null) return;errorHandler () } publicfunctioninsert (sql:String,completeHandler:Function,errorHandler:Function=null): void {varst:Statement=mConnection.createStatement (); vartoken:MySqlToken=st.executeQuery (sql); varresponder:AsyncResponder=newAsyncResponder (resultHandler,faultHandler,token); token.addResponder (responder); functionresultHandler (result:Object/*MySqlResponse*/,token:Object/*MySqlToken*/): void {completeHandler (result.insertID);} functionfaultHandler (info:Object,token:Object): void {if (errorHandler==null) return;errorHandler () } publicfunctionremove (sql:String,completeHandler:Function,errorHandler:Function=null): void {varst:Statement=mConnection.createStatement (); vartoken:MySqlToken=st.executeQuery (sql); varresponder:AsyncResponder=newAsyncResponder (resultHandler,faultHandler,token); token.addResponder (responder); functionresultHandler (result:Object/*MySqlResponse*/,token:Object/*MySqlToken*/): void {completeHandler ();} functionfaultHandler (info:Object,token:Object): void {if (errorHandler==null) return;errorHandler ();}

There are three methods, select,insert,remove, which correspond to select,insert,delete in the SQL statement.

How to connect AS3 to a MySQL database

The usage is simple: connect first:

VardatabaseData:DataBaseData=newDataBaseData (); databaseData.host= "127.0.0.1"; databaseData.database= "game"; databaseData.password= "123456"; databaseData.port=3306;databaseData.username= "root"; vardataBase:DataBase=newDataBase (databaseData); dataBase.addEventListener (Event.CONNECT,onConnected); dataBase.connect (); functiononConnected (event:Event): void {dataBase.removeEventListener (Event.CONNECT,onConnected); dispatchEvent (newEvent (Event.COMPLETE);}

If you don't need it, you can disconnect it first:

DataBase.disconnect ()

Here is the select statement:

Varsql:String= "selectid, namefrom`npc`"; dataBase.select (sql,endQuery); functionendQuery (data:Array): void {varnpcList:Array= []; foreach (varitem:Objectindata) {varnpc:Object= {id:item.id,name:item.name}; npcList.push (npc);}}

The usage of the insert statement returns an insertID, that is, the ID of the data being inserted.

At this point, the study on "how to connect AS3 to MySQL database" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
