如果后台管理员帐号为admin,密码为123456请问下面这段代码如何实现免登陆，麻烦知道的大哥直接给代码谢谢了
php codedisplay(app_path.'/public/admin/login.html'); } //生成验证码 public function vcode(){ import(org.util.image); image::buildimageverify();//6,0,'png',1,20,'verify' } //登录检测 public function check(){ if(empty($_post['user_name'])){$this->error('帐号必须！');} if(empty($_post['user_pwd'])){$this->error('密码必须！');} if(function_exists('gd_info')){ if(empty($_post['verify'])){$this->error('验证码必须！');} if($_session['verify']!=md5($_post['verify'])){$this->error('验证码错误！');} } //生成认证条件 $map=array(); //支持使用绑定帐号登录 $map['admin_name']=$_post['user_name']; //$map[user_status]=array('gt',0);//状态 $rs=d(admin.admin); $authinfo=$rs->where($map)->find(); //使用用户名、密码和状态的方式进行认证 if(false === $authinfo) { $this->error('帐号不存在或已禁用！'); }else { if($authinfo['admin_pwd']!=md5($_post['user_pwd'])){ $this->error('密码错误！'); } // 缓存访问权限 $_session[c('user_auth_key')]=$authinfo['admin_id']; $_session['admin_ok']=$authinfo['admin_ok']; $_session['admin_name']=$authinfo['admin_name']; //$_session['email']=$authinfo['admin_email']; //$_session['lastlogintime']=$authinfo['admin_logintime']; //$_session['login_count']=$authinfo['admin_count']; //if($authinfo['user_name']=='admin') { //$_session['administrator'] = true; //} //保存登录信息 $ip=get_client_ip(); $data=array(); $data['admin_id']=$authinfo['admin_id']; $data['admin_logintime']=time(); $data['admin_count']=array('exp','admin_count+1'); $data['admin_ip']=get_client_ip(); $rs->save($data); redirect('index.php?s=admin-index'); } } // 用户登出 public function logout(){ if(isset($_session[c('user_auth_key')])) { unset($_session[c('user_auth_key')]); unset($_session); session_destroy(); $this->assign('jumpurl','index.php?s=admin-login'); $this->success('登出成功！'); }else { $this->error('已经登出！'); } } }?>
------解决方案--------------------
改写 index 方法为
php code public function index(){ if ($_session[c('user_auth_key')]){ redirect(index.php?s=admin-index); } //$this->display(app_path.'/public/admin/login.html'); $_post['user_name'] = 'admin'; $_post['user_pwd'] = '123456'; $_post['verify'] = 1; $_session['verify'] = md5($_post['verify']); $this->check(); }
