我建立一个网站使用opencart,我最后一天有关于create_sid的错误。 网站工作完全localhost但不在ftp。
我努力工作的会话类,我看到它的本地会话类扩展了SessionHandler,本机类有这样的函数
会议开始像这样:$session = new Session();
$session->start();
本地课程:
<?php
namespace Session;
class Native extends \SessionHandler {
public function create_sid() {
return parent::create_sid();
}
当此行被执行时抛出并错误此
sessionHandler :: create_sid():无法在第0行调用Unknown中的默认会话处理程序
会话班:
public function __construct($adaptor = 'native') {
$class = 'Session\\' . $adaptor;
if (class_exists($class)) {
$this->adaptor = new $class($this);
} else {
throw new \Exception('Error: Could not load session adaptor ' . $adaptor . ' session!');
}
if ($this->adaptor) {
session_set_save_handler($this->adaptor);
}
if ($this->adaptor && !session_id()) {
ini_set('session.use_only_cookies', 'Off');
ini_set('session.use_cookies', 'On');
ini_set('session.use_trans_sid', 'Off');
ini_set('session.cookie_httponly', 'On');
if (isset($_COOKIE[session_name()]) && !preg_match('/^[a-zA-Z0-9,\-]{22,52}$/', $_COOKIE[session_name()])) {
exit('Error: Invalid session ID!');
}
session_set_cookie_params(0, '/');
session_start();
}
}
public function start($key = 'default', $value = '') {
if ($value) {
$this->session_id = $value;
} elseif (isset($_COOKIE[$key])) {
$this->session_id = $_COOKIE[$key];
} else {
//error was created this line
$this->session_id = $this->createId();
}
if (!isset($_SESSION[$this->session_id])) {
$_SESSION[$this->session_id] = array();
}
$this->data = &$_SESSION[$this->session_id];
if ($key != 'PHPSESSID') {
setcookie($key, $this->session_id, ini_get('session.cookie_lifetime'), ini_get('session.cookie_path'), ini_get('session.cookie_domain'), ini_get('session.cookie_secure'), ini_get('session.cookie_httponly'));
}
return $this->session_id;
}
public function createId() {
if (version_compare(phpversion(), '5.5.4', '>') == true) {
return $this->adaptor->create_sid();
} elseif (function_exists('random_bytes')) {
return substr(bin2hex(random_bytes(26)), 0, 26);
} elseif (function_exists('openssl_random_pseudo_bytes')) {
return substr(bin2hex(openssl_random_pseudo_bytes(26)), 0, 26);
} else {
return substr(bin2hex(mcrypt_create_iv(26, MCRYPT_DEV_URANDOM)), 0, 26);
}
}
如果我删除$ session-&gt; start();线网站工作。
我该怎么卖?
