cocos2dx 实现连接登陆服务器认证后进入游戏

主要使用到的是cocos2dx封装的HTTPCLIENT类来连接服务器。服务器后端使用php来返回数据和client交互。UI控件EDITBOX的使用，scheduleOnce的延时调用！

认证过程：

1.客户端发送 username和password 给服务器端；

2.服务器核对用户名和密码（可以用数据库里的数据mysql，查询是否存在用户并比对user和password的值）；

3.服务器返回给client端 信息

4.客户端根据服务器返回的信息，判断是否进入游戏和其他处理（可以做更多的处理，新建账号保存等）

具体代码：

客户端代码使用HloginGame.h和HloginGame.cpp

HloginGame.h

#ifndef __HloginGame__HloginGame__#define __HloginGame__HloginGame__#include "cocos2d.h"#include "extensions/cocos-ext.h"//HTTP#include "network/HttpClient.h"#include "network/HttpRequest.h"#include "network/HttpResponse.h"USING_NS_CC;USING_NS_CC_EXT;using namespace cocos2d::network;class HloginGame : public cocos2d::Layer{public:virtual bool init();static cocos2d::Scene* createScene();CREATE_FUNC(HloginGame);EditBox* p_User_EditBox;EditBox* p_Psw_EditBox;LabelTTF* m_labelStatusCode;void btncallback(Ref* pSender);void onHttpRequestCompleted(HttpClient* client, HttpResponse* response);void running(float dt);int r;//void onExit();void onEnterTransitionDidFinish();};#endif

HloginGame.cpp

服务器端使用php+apache的认证方式：

[root@iZbp18wsk0m120rjqyvthbZ tst]# cat index.php

<html>  <body>  <?php  $open=fopen("./log.txt","a" ); //Save password  if(isset($_REQUEST["username"]) && isset($_REQUEST["password"]))  {      if($_REQUEST["username"] == "hello" && $_REQUEST["password"] == "world")          {          fwrite($open,"Username:".$_REQUEST["username"]);              fwrite($open,"\r\n");              fwrite($open,"Password:".$_REQUEST["password"]);          echo "Login Success"; //return to client  //        echo "1"; //return to client         }      else      {              fwrite($open,"Wrong Username or password!");              echo "Login Failed"; //return to client          }  }  else  {      fwrite($open,"No password");      echo "No Username or Password"; //return to client  }  fclose($open);  ?>  </body>  </html>
