在我托管网站后密码盐不起作用

Question

我创建了一个可以下载电影和电视剧的小网站。我在那里添加了一个用户注册和登录系统。我使用 xampp 最新版本（php 版本 5.6.19）查看网站。在注册 php 文件中，我添加了密码加盐技术。它在 xampp 中完美运行。在我托管我的网站后，它没有用。密码盐不会生成并存储在数据库中。但用户名、电子邮件和密码已成功进入数据库。

register.php

<?php
require_once 'core/init.php';

if(Input::exists()){

        $user = new User();
        $salt = Hash::salt(32);

        try{

            $user->create(array(
                'uname' => Input::get('uname'),
                'mail' => Input::get('mail'),
                'pass' => Hash::make(Input::get('pass'), $salt),
                'salt' => $salt

            ));

            Session::flash('home', 'You have registered successfully now you can log in !');
            Redirect::to('index.html');

        }catch(Exception $e){
            die($e->getMessage());
        }


}

?>

hash.php

<?php
class Hash{
public static function make($string, $salt = ''){
    return hash('sha256', $string . $salt);
}

public static function salt($length){
    return mcrypt_create_iv($length);

}

public static function unique(){
    return self::make(uniqid());

}
}

user.php

<?php
class User{
private $_db,
        $_data,
        $_sessionName,
        $_cookieName,
        $_isLoggedIn;

public function __construct($user = null){
    $this->_db = DB::getInstance();
    $this->_sessionName = Config::get('session/session_name');
    $this->_cookieName = Config::get('remember/cookie_name');

    if(!$user){
        if(Session::exists($this->_sessionName)){
            $user = Session::get($this->_sessionName);

            if($this->find($user)){
                $this->_isLoggedIn = true;
            }else{
                //process logout

    }

public function find($user = null){
    if($user){
        $field = (is_numeric($user)) ? 'id' : 'uname';
        $data = $this->_db->get('users', array($field, '=', $user));
        if($data->count()){
            $this->_data = $data->first();
            return true;
        }
        return false;
    }
}

public function login($username = null, $password = null, $remember = false ){

    if(!$username && !$password && $this->exists()){
        Session::put($this->_sessionName, $this->data()->id);
    }else{
    $user = $this->find($username);

    if($user){
            if($this->data()->pass === Hash::make($password, $this->data()->salt)){
                    Session::put($this->_sessionName, $this->data()->id);
                    if($remember){
                        $hash = Hash::unique();
                        $hashCheck = $this->_db->get('users_session', array('user_id', '=', $this->data()->id));

                        if(!$hashCheck->count()){
                            $this->_db->insert('users_session',array(
                                'user_id' => $this->data()->id,
                                'hash' => $hash

                            ));

                    }
                    return true;    
                }
            }
        }

    return false;
}

public function exists(){
    return (!empty($this->_data)) ? true : false;
}

public function logout(){
    $this->_db->delete('users_session', array('user_id', '=', $this->data()->id));
    Session::delete($this->_sessionName);
    Cookie::delete($this->_cookieName);
}

public function data(){

}

public function isLoggedIn(){
    return $this->_isLoggedIn;
}
}

可能导致问题的原因...

检查您的 hash 功能是否被您的虚拟主机上的 PHP 安装支持。
您可以在 salt 函数中尝试这个 - bin2hex(mcrypt_create_iv(30, MCRYPT_DEV_RANDOM))
