SmartFoxServer服务器端用户登录验证

说明：本示例演示的是一个 SmartFoxServer 服务器端用户登录验证。 
开发环境：Unity3d 2.6，SmartFoxServer 1.6.6，MyEclipse 
一，首先先写一个服务器端扩展的 Java 类。如下所示 

package com.song.unity3d.login; import java.nio.channels.SocketChannel; import java.util.LinkedList; import it.gotoandplay.smartfoxserver.data.User; import it.gotoandplay.smartfoxserver.data.Zone; import it.gotoandplay.smartfoxserver.events.InternalEventObject; import it.gotoandplay.smartfoxserver.exceptions.LoginException; import it.gotoandplay.smartfoxserver.extensions.AbstractExtension; import it.gotoandplay.smartfoxserver.extensions.ExtensionHelper; import it.gotoandplay.smartfoxserver.lib.ActionscriptObject; /**  *  * @author songvery  * @version 2011-03-09-01  *  */ public class MyExtension extends AbstractExtension {  private ExtensionHelper helper;    private Zone currentZone;    //private DbManager db;    LinkedList<SocketChannel> recipients;        public void init(){   recipients=new LinkedList<SocketChannel>();   helper = ExtensionHelper.instance();   this.currentZone = helper.getZone(this.getOwnerZone());  }    public void destory(){       }    public void handleRequest(String cmd, ActionscriptObject ao, User user,    int fromRoom) {   // TODO Auto-generated method stub     }  public void handleRequest(String cmd, String[] params, User user, int fromRoom) {   // TODO Auto-generated method stub     }  public void handleInternalEvent(InternalEventObject ie) {      if(ie.getEventName().equals("loginRequest")){    ActionscriptObject response=new ActionscriptObject();        User loginUser=null;        //用户名    String name=ie.getParam("nick");        //密码    String pwd=ie.getParam("pass");        //ScocketChannel        SocketChannel chan=(SocketChannel)ie.getObject("chan");        //String serverRandom=helper.getSecretKey(chan);        //省去查询数据库验证的操作，自己写吧！    if(name.equals(pwd)){     try{      loginUser=helper.canLogin(name, pwd, chan, this.currentZone.getName());            response.put("cmd", "loginOK");      response.put("id", String.valueOf(loginUser.getUserId()));      response.put("name", loginUser.getName());           }catch(LoginException e){      response.put("cmd", "loginKO");      response.put("err", e.getMessage());     }      }else{     response.put("cmd", "loginKO");     response.put("err", "error password");    }    recipients.add(chan);    this.sendResponse(response, -1, null, recipients);    this.helper.sendRoomList(chan);   }     } } 

其中的一些不明白的地方，大家到网上自己查询。 
二，将写好的 MyExtension.java 编译成 MyExtension.class 文件。我的 SmartFoxServer 安装在 D 盘下。所以将编 译好的文件拷贝到 D:\Program Files\SmartFoxServerPRO_1.6.6\Server\javaExtensions\com\song\unity3d \login 文 件夹下. 
三，打开 D:\Program Files\SmartFoxServerPRO_1.6.6\Server 目录下的 config.xml 文件。将如下代码拷贝 到<Zones></Zones>区间。保存后重启 SmartFoxServer 服 务器. 

<Zone name="firstZone" uCountUpdate="true" buddyList="20" maxUsers="4000" customLogin="true">     <Rooms>      <Room name="The Hall" maxUsers="50" isPrivate="false" isTemp="false" autoJoin="true" uCountUpdate="true" />     </Rooms>         <Extensions>      <Extension name="firstSFS" className="com.song.unity3d.login.MyExtension" type="java" />     </Extensions>    </Zone> 

四，在 Unity3d 中创建一个 C#文件。代码如下所示. 

using UnityEngine; using System; using System.Collections;     using SmartFoxClientAPI; using SmartFoxClientAPI.Util; using SmartFoxClientAPI.Data;   /*  * @author songvery  * @version 2011-03-09-01  * @infomation 请输入相同的用户名和密码，服务器端扩展做的是用户名=密码 的验证简单验证  * */ public class ConnectionGUI: MonoBehaviour {    private SmartFoxClient smartFox;    private bool shuttingDown = false;    private string serverName = "127.0.0.1";//服务器 IP    private int serverPort = 9339;//服务器端口号    private string zone = "firstZone";    private string username="songvery";//用户名      private string password="";//密码    private string errorMessage = "";//错误信息    private string extensionName="";//服务器端扩展名    /*   * 构造函数   * */  public ConnectionGUI(){   extensionName="firstSFS";  }    void OnApplicationQuit() {   shuttingDown = true;  }    private bool connectionAttempt = false;      // Use this for initialization  void Start () {       Application.runInBackground = true;      bool debug=true;      if(SmartFox.IsInitialized()){        smartFox=SmartFox.Connection;       }else{        try{     smartFox=new SmartFoxClient(debug);     smartFox.runInQueueMode = true;    }catch(Exception e){     errorMessage=e.ToString();    }   }      SFSEvent.onConnection += OnConnection;   SFSEvent.onConnectionLost += OnConnectionLost;   SFSEvent.onLogin += OnLogin;   SFSEvent.onRoomListUpdate += OnRoomListUpdate;   SFSEvent.onDebugMessage += OnDebugMessage;     SFSEvent.onExtensionResponse += OnExtensionResponse;//注册一个 SFSEvent 事 件  }    void FixedUpdate() {   smartFox.ProcessEventQueue();  }    private void UnregisterSFSSceneCallBacks(){   SFSEvent.onConnection-=OnConnection;   SFSEvent.onConnectionLost-=OnConnectionLost;   SFSEvent.onLogin-=OnLogin;   SFSEvent.onRoomListUpdate-=OnRoomListUpdate;   SFSEvent.onDebugMessage-=OnDebugMessage;   SFSEvent.onExtensionResponse -= OnExtensionResponse;  }    void OnConnection(bool success,string error){   if(success){    SmartFox.Connection=smartFox;   }else{    errorMessage=error;   }  }      void OnConnectionLost(){   Debug.Log("OnConnectionLost");   errorMessage="connection lost/No connnection to server";  }    void OnDebugMessage(string message){   Debug.Log("SFSDEBUG ----"+message);  }    /**   * 尝试与服务器的连接   * */  void ConnectToServer(){   try{    smartFox.Connect(serverName,serverPort);   }catch(Exception e){    errorMessage=e.ToString();    //Application.ExternalEval ("history.go(-1);");   }  }    void OnGUI() {       if (!connectionAttempt) {         connectionAttempt = true;     ConnectToServer();    }   else if (smartFox.IsConnected()) {    // Login    GUI.Label(new Rect(10, 116, 100, 100), "Username: ");      username = GUI.TextField(new Rect(100, 116, 200, 20), this.username, 25);        GUI.Label(new Rect(10,156,100,100),"Password: ");      password=GUI.PasswordField(new Rect(100,156,200,20),this.password,"*"[0],25);      GUI.Label(new Rect(10, 190, 100, 100), errorMessage);      if ( GUI.Button(new Rect(100, 230, 100, 24), "Login")  || (Event.current.type == EventType.keyDown && Event.current.character == '\n')) {          smartFox.Login(zone, username, password);    }     } else {      GUI.Label(new Rect(10, 150, 100, 100), "Waiting for connection");    GUI.Label(new Rect(10, 190, 100, 100), errorMessage);   }  }      void OnLogin(bool success, string name, string error){   if(success){    Debug.Log("Hello:Welcome "+name);   }else{    errorMessage=error;   }     }    void OnRoomListUpdate(Hashtable roomList){   UnregisterSFSSceneCallBacks();   Application.LoadLevel("game");  }    /**   * 从服务器端扩展接收的信息处理   * */  public void OnExtensionResponse(object data, string type) {      // We only use XML based messages in this tutorial, so ignore string and json types   if ( type == SmartFoxClient.XTMSG_TYPE_XML ) {    // For XML based communication the data object is a SFSObject    SFSObject dataObject = (SFSObject)data;    switch(dataObject.GetString("cmd")){    case "loginOK":      //说明用户登录成功     Debug.Log("You pass validation!");     smartFox.myUserName = dataObject.GetString("name");//服务器端传递的用户名       smartFox.myUserId = int.Parse(dataObject.GetString("id"));//服务器端传递的 ID     break;    case "loginKO":      //登录失败,在这可以做相应的处理，如跳转到注册的页面。。。     errorMessage="You not pass validation!";     break;    }   }  } }
