SFS2X 例子(java 扩展加as 客户端)

这两天熟悉了一下SFS2X的部署开发流程,试着写了一个小例子.笔记一下.

例子的流程是:

1.在admintool里创建zone:sfs2x_demo,将其自定义登陆开启.

2.在admintool里创建Room: station.

3.根据客户端的配置文件sfs-config.xml连接到SFS.

4.自定义登陆,验证用户名和密码的合法性.

5.加入房间,

6.设置用户变量,创建客户端avatar.保存位置到用户变量里去.

7.发扩展,avatar走路通知同房间内的所有用户.

8.监听用户离开事件.清除avatar..

最后,将写好的扩展打成jar包放在SFS2X-RC1\SFS2X\extensions\golastroom\目录下,在admintool里配置一下zone的扩展,注意golastroom的扩展文件名须和AdmonTool配置里zone的扩展名字一样.

这样,每个登陆到此zone的用户都必须通过自定义扩展模块的验证..

服务端java

package com.golastroom.extension;

import com.golastroom.eventHandler.LoginEventHandler;
import com.golastroom.requestHandler.MoveReqHandler;
import com.smartfoxserver.v2.annotations.Instantiation;
import com.smartfoxserver.v2.annotations.Instantiation.InstantiationMode;
import com.smartfoxserver.v2.core.SFSEventType;
import com.smartfoxserver.v2.extensions.SFSExtension;


@Instantiation(InstantiationMode.SINGLE_INSTANCE)
public class MyFirstExtension extends SFSExtension {

@Override
public void init() {
   trace("=============golastroom ==============");
   addRequestHandler("move", MoveReqHandler.class);
   addEventHandler(SFSEventType.USER_LOGIN, LoginEventHandler.class);
}

@Override
public void destroy() {

   super.destroy();
}

}

扩展里初始化方法里将处理avatar移动的处理模块和自定义登陆模块注册添加进去.

登陆处理模块

package com.golastroom.eventHandler;

import com.smartfoxserver.bitswarm.sessions.ISession;
import com.smartfoxserver.v2.core.ISFSEvent;
import com.smartfoxserver.v2.core.SFSEventParam;
import com.smartfoxserver.v2.entities.data.ISFSObject;
import com.smartfoxserver.v2.exceptions.SFSException;
import com.smartfoxserver.v2.exceptions.SFSLoginException;
import com.smartfoxserver.v2.extensions.BaseServerEventHandler;

public class LoginEventHandler extends BaseServerEventHandler {

@Override
public void handleServerEvent(ISFSEvent event) throws SFSException {
   String name =(String)event.getParameter(SFSEventParam.LOGIN_NAME);
   String pass = (String) event.getParameter(SFSEventParam.LOGIN_PASSWORD);
   ISession session = (ISession) event.getParameter(SFSEventParam.SESSION);
   ISFSObject paramsOut = (ISFSObject) event.getParameter(SFSEventParam.LOGIN_OUT_DATA);
   trace(name +" is login .. ");
   if (name.startsWith("h_") && getApi().checkSecurePassword(session, "123", pass)){
    paramsOut.putBool("login", true);
   }else{
    paramsOut.putBool("login", false);
    //throw new SFSLoginException("用户名必须以\"h_\"开头且密码为:123");
   }

}
}

 

自定义登陆安全验证只是简单验证此用户的用户名必须以h_开头且密码为123为合法用户,返回登陆验证结果.

avatar移动处理模块

package com.golastroom.requestHandler;

import com.smartfoxserver.v2.annotations.Instantiation;
import com.smartfoxserver.v2.annotations.Instantiation.InstantiationMode;
import com.smartfoxserver.v2.entities.Room;
import com.smartfoxserver.v2.entities.User;
import com.smartfoxserver.v2.entities.data.ISFSObject;
import com.smartfoxserver.v2.extensions.BaseClientRequestHandler;

@Instantiation(InstantiationMode.SINGLE_INSTANCE)
public class MoveReqHandler extends BaseClientRequestHandler {

@Override
public void handleClientRequest(User sender, ISFSObject params) {
   trace(sender.getName()," request!! ");
   Room room = sender.getLastJoinedRoom();

   params.putUtfString("name", sender.getName());
   send("p", params, room.getUserList());
}

}

移动处理很简单,只是将用户提交的移动数据转发一下,同时将谁移动了也发给所有用户.
