uchome登录验证

Uchome采用cookie+数据库的方式来进行用户登录验证的

一。登录

1：登录表单由source/do_login.php 处理

2：然后验证用户名以及密码的正确性，不正确则跳转并提示登录失败

3：若验证通过之后，再将获取到得用户账户信息赋给setarr变量数组

4：更新member表

5：将用户登录信息写入到Uchome的session表中

6：将用户名与密码加密写入cookie中

if(submitcheck('loginsubmit')) {

    $password = $_POST['password'];
    $username = trim($_POST['username']);
    $cookietime = intval($_POST['cookietime']);
    
    $cookiecheck = $cookietime?' checked':'';
    $membername = $username;
    
    if(empty($_POST['username'])) {
        showmessage('users_were_not_empty_please_re_login', 'do.php?ac='.$_SCONFIG['login_action']);
    }
    
    if($_SCONFIG['seccode_login']) {
        include_once(S_ROOT.'./source/function_cp.php');
        if(!ckseccode($_POST['seccode'])) {
            $_SGLOBAL['input_seccode'] = 1;
            include template('do_login');
            exit;
        }
    }

    //同步获取用户源
    if(!$passport = getpassport($username, $password)) {
        showmessage('login_failure_please_re_login', 'do.php?ac='.$_SCONFIG['login_action']);
    }
    
    $setarr = array(
        'uid' => $passport['uid'],
        'username' => addslashes($passport['username']),
        'password' => md5("$passport[uid]|$_SGLOBAL[timestamp]")//本地密码随机生成
    );
    
    include_once(S_ROOT.'./source/function_space.php');
    //开通空间
    $query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('space')." WHERE uid='$setarr[uid]'");
    if(!$space = $_SGLOBAL['db']->fetch_array($query)) {
        $space = space_open($setarr['uid'], $setarr['username'], 0, $passport['email']);
    }
    
    $_SGLOBAL['member'] = $space;
    
    //实名
    realname_set($space['uid'], $space['username'], $space['name'], $space['namestatus']);
    
    //检索当前用户
    $query = $_SGLOBAL['db']->query("SELECT password FROM ".tname('member')." WHERE uid='$setarr[uid]'");    
    if($value = $_SGLOBAL['db']->fetch_array($query)) {
        $setarr['password'] = addslashes($value['password']);
    } else {
        //更新本地用户库
        inserttable('member', $setarr, 0, true);
    }

    //清理在线session
    insertsession($setarr);
    
    //设置cookie
    ssetcookie('auth', authcode("$setarr[password]	$setarr[uid]", 'ENCODE'), $cookietime);         //加密cookie:  passowrd和uid 
    ssetcookie('loginuser', $passport['username'], 31536000);
    ssetcookie('_refer', '');
    
    //同步登录
    if($_SCONFIG['uc_status']) {
        include_once S_ROOT.'./uc_client/client.php';
        $ucsynlogin = uc_user_synlogin($setarr['uid']);
    } else {
        $ucsynlogin = '';
    }
    
    //好友邀请
    if($invitearr) {
        //成为好友
        invite_update($invitearr['id'], $setarr['uid'], $setarr['username'], $invitearr['uid'], $invitearr['username'], $app);
    }
    $_SGLOBAL['supe_uid'] = $space['uid'];

    //判断用户是否设置了头像
    $reward = $setarr = array();
    $experience = $credit = 0;
    $avatar_exists = ckavatar($space['uid']);
    if($avatar_exists) {
        if(!$space['avatar']) {
            //奖励积分
            $reward = getreward('setavatar', 0);
            $credit = $reward['credit'];
            $experience = $reward['experience'];
            if($credit) {
                $setarr['credit'] = "credit=credit+$credit";
            }
            if($experience) {
                $setarr['experience'] = "experience=experience+$experience";
            }
            $setarr['avatar'] = 'avatar=1';
            $setarr['updatetime'] = "updatetime=$_SGLOBAL[timestamp]";
        }
    } else {
        if($space['avatar']) {
            $setarr['avatar'] = 'avatar=0';
        }
    }
    
    if($setarr) {
        $_SGLOBAL['db']->query("UPDATE ".tname('space')." SET ".implode(',', $setarr)." WHERE uid='$space[uid]'");//更新空间信息
    }

    if(empty($_POST['refer'])) {
        $_POST['refer'] = 'space.php?do=home';
    }
    
    realname_get();
    
    showmessage('login_success', $app?"userapp.php?id=$app":$_POST['refer'], 1, array($ucsynlogin));
}

二。验证

1.cp.php

//权限判断
if(empty($_SGLOBAL['supe_uid'])) {　　　　　　　　　　　　　　　　　　//检查supe_uid
    if($_SERVER['REQUEST_METHOD'] == 'GET') {
        ssetcookie('_refer', rawurlencode($_SERVER['REQUEST_URI'])); //保存网站链接，登录后跳转
    } else {
        ssetcookie('_refer', rawurlencode('cp.php?ac='.$ac));
    }
    showmessage('to_login', 'do.php?ac='.$_SCONFIG['login_action']);
}

2.space.php

//是否公开
if(empty($isinvite) && empty($_SCONFIG['networkpublic'])) {
    checklogin();//需要登录
}

//检查是否登录
function checklogin() {
    global $_SGLOBAL, $_SCONFIG;

    if(empty($_SGLOBAL['supe_uid'])) {　　　　　　　　　　　　　　　　　　　　　　　//同样是检查supe_uid
        ssetcookie('_refer', rawurlencode($_SERVER['REQUEST_URI']));
        showmessage('to_login', 'do.php?ac='.$_SCONFIG['login_action']);
    }
}

//判断当前用户登录状态
function checkauth() {
    global $_SGLOBAL, $_SC, $_SCONFIG, $_SCOOKIE, $_SN;

    if($_SGLOBAL['mobile'] && $_GET['m_auth'])
　　　　 $_SCOOKIE['auth'] = $_GET['m_auth'];

    if($_SCOOKIE['auth']) {
        @list($password, $uid) = explode("	", authcode($_SCOOKIE['auth'], 'DECODE'));                  //解密cookie:password和uid
        $_SGLOBAL['supe_uid'] = intval($uid);
        if($password && $_SGLOBAL['supe_uid']) {
　　　　　　　　//判断cookie时保存的内容 是否与 session表或member表里的相同。
            $query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('session')." WHERE uid='$_SGLOBAL[supe_uid]'");
            if($member = $_SGLOBAL['db']->fetch_array($query)) {
                if($member['password'] == $password) {
                    $_SGLOBAL['supe_username'] = addslashes($member['username']);
                    $_SGLOBAL['session'] = $member;
                } else {
                    $_SGLOBAL['supe_uid'] = 0;
                }
            } else {
                $query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('member')." WHERE uid='$_SGLOBAL[supe_uid]'");
                if($member = $_SGLOBAL['db']->fetch_array($query)) {
                    if($member['password'] == $password) {
                        $_SGLOBAL['supe_username'] = addslashes($member['username']);
                        $session = array('uid' => $_SGLOBAL['supe_uid'], 'username' => $_SGLOBAL['supe_username'], 'password' => $password);
                        include_once(S_ROOT.'./source/function_space.php');
                        insertsession($session);//登录
                    } else {
                        $_SGLOBAL['supe_uid'] = 0;
                    }
                } else {
                    $_SGLOBAL['supe_uid'] = 0;
                }
            }
        }
    }
   //都不相同，则清除cookie
    if(empty($_SGLOBAL['supe_uid'])) {
        clearcookie();
    } else {
        $_SGLOBAL['username'] = $member['username'];
    }
}
