我正在尝试在CodeIgniter应用程序中实现CAS身份验证,但我找不到当前是否有任何库设置它。我正在管理,只是包括该类并添加一些脏的修复,但如果有人知道一个合适的库我认为这将是一个更清洁的解决方案。
我一直在寻找这里以及谷歌各地的一系列帖子,但似乎在我需要的东西上做得不够。唯一相关的地方是VCU Libraries上的帖子,但不包括图书馆下载链接。
谢谢大家!

更新:您可以在Github找到最新版本的库:https://github.com/eliasdorneles/code-igniter-cas-library
您也可以通过sparks http://getsparks.org/packages/cas-auth-library/versions/HEAD/show
安装
我已经启动了一个CAS库来简化为CodeIgniter设置CAS身份验证,它依赖于现有的phpCAS。
要开始使用它,只需在某个可访问的目录中安装phpCAS,将库文件放在application/libraries/Cas.php
中并创建一个配置文件config/cas.php
,如下所示:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$config['cas_server_url'] = 'https://yourserver.com/cas';
$config['phpcas_path'] = '/path/to/phpCAS-1.3.1';
$config['cas_disable_server_validation'] = TRUE;
// $config['cas_debug'] = TRUE; // <-- use this to enable phpCAS debug mode
然后,在您的控制器中,您将能够这样做:
function index() {
$this->load->library('cas');
$this->cas->force_auth();
$user = $this->cas->user();
echo "Hello, $user->userlogin!";
}
这是库文件(必须命名为 Cas.php ):
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
function cas_show_config_error(){
show_error("CAS authentication is not properly configured.<br /><br />
Please, check your configuration for the following file:
<code>config/cas.php</code>
The minimum configuration requires:
<ul>
<li><em>cas_server_url</em>: the <strong>URL</strong> of your CAS server</li>
<li><em>phpcas_path</em>: path to a installation of
<a href=\"https://wiki.jasig.org/display/CASC/phpCAS\">phpCAS library</a></li>
<li>and one of <em>cas_disable_server_validation</em> and <em>cas_ca_cert_file</em>.</li>
</ul>
");
}
class Cas {
public function __construct(){
if (!function_exists('curl_init')){
show_error('<strong>ERROR:</strong> You need to install the PHP module <strong>curl</strong>
to be able to use CAS authentication.');
}
$CI =& get_instance();
$this->CI = $CI;
$CI->config->load('cas');
$this->phpcas_path = $CI->config->item('phpcas_path');
$this->cas_server_url = $CI->config->item('cas_server_url');
if (empty($this->phpcas_path)
or filter_var($this->cas_server_url, FILTER_VALIDATE_URL) === FALSE) {
cas_show_config_error();
}
$cas_lib_file = $this->phpcas_path . '/CAS.php';
if (!file_exists($cas_lib_file)){
show_error("Could not find file: <code>" . $cas_lib_file. "</code>");
}
require_once $cas_lib_file;
if ($CI->config->item('cas_debug')) {
phpCAS::setDebug();
}
// init CAS client
$defaults = array('path' => '', 'port' => 443);
$cas_url = array_merge($defaults, parse_url($this->cas_server_url));
phpCAS::client(CAS_VERSION_2_0, $cas_url['host'],
$cas_url['port'], $cas_url['path']);
// configures SSL behavior
if ($CI->config->item('cas_disable_server_validation')){
phpCAS::setNoCasServerValidation();
} else {
$ca_cert_file = $CI->config->item('cas_server_ca_cert');
if (empty($ca_cert_file)) {
cas_show_config_error();
}
phpCAS::setCasServerCACert($ca_cert_file);
}
}
/**
* Trigger CAS authentication if user is not yet authenticated.
*/
public function force_auth()
{
phpCAS::forceAuthentication();
}
/**
* Return an object with userlogin and attributes.
* Shows aerror if called before authentication.
*/
public function user()
{
if (phpCAS::isAuthenticated()) {
$userlogin = phpCAS::getUser();
$attributes = phpCAS::getAttributes();
echo "has attributes? ";
var_dump(phpCAS::hasAttributes());
return (object) array('userlogin' => $userlogin,
'attributes' => $attributes);
} else {
show_error("User was not authenticated yet.");
}
}
/**
* Logout and redirect to the main site URL,
* or to the URL passed as argument
*/
public function logout($url = '')
{
if (empty($url)) {
$this->CI->load->helper('url');
$url = base_url();
}
phpCAS::logoutWithRedirectService($url);
}
}

我建议使用Ion Auth Library,它基于Redux Auth,它已经过时了。 Ion Auth重量轻,易于定制,可满足您的需求。 Ion Auth是CodeIgniter最好的身份验证库之一。

究竟什么不能用于VCU库?
您可以在PHP中执行任何操作,您可以在CodeIgniter中执行。 所以你可以使用PHP CAS客户端: http://www.jasig.org/phpcas-121-final-release
以下是如何进行身份验证的示例。
