Restler 3.0基本身份验证

restler basic-authentication php

我正在尝试Restler为我的新项目构建web api。
其中一个要求是简单的身份验证。
我在SO上找到了一个很好的例子 https://stackoverflow.com/a/7969250/965722 但这是给Restler 2的。使用手册,我成功地将该类转换为Restler 3.0

<?php
class BasicAuthentication implements iAuthenticate
{
    const REALM = 'Restricted API';
    public static $currentUser;
    public static $requires = 'user';
    public static $role = 'user';

    public function __isAllowed()
    {
        if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
        {
            $user = $_SERVER['PHP_AUTH_USER'];
            $pass = $_SERVER['PHP_AUTH_PW'];
            $user = mysql_real_escape_string($user);
            $pass = mysql_real_escape_string($pass);

            $roles = array('12345' => 'user', '67890' => 'admin');

            if (!isset($pass) || !array_key_exists($pass, $roles))
            {
                return false;
            }

            static ::$role = $roles[$pass];
            Resources::$accessControlFunction = 'AccessControl::verifyAccess';
            return static ::$requires == static ::$role || static ::$role == 'admin';
        }
        header('WWW-Authenticate: Basic realm="' . self::REALM . '"');
        throw new RestException(401, 'Basic Authentication Required');
    }

    /**
     * @access private
     */
    public static function verifyAccess(array $m)
    {
        $requires = isset($m['class']['AccessControl']['properties']['requires']) ? $m['class']['AccessControl']['properties']['requires'] : false;
        return $requires ? static ::$role == 'admin' || static ::$role == $requires : true;
    }
}
?>

我的示例api类如下所示:

<?php
class Api
{
    /**
     * @url GET
     * @url GET hello
     * @url GET hello/{to}
     */
    function hello($to = 'world')
    {
        return "Hello $to!";
    }
    /**
     * @access protected
     * @class  AccessControl {@requires user}
     */
    public function user()
    {
        return "protected api, only user and admin can access";
    }
    /**
     * @access protected
     * @class  AccessControl {@requires admin}
     */
    public function admin()
    {
        return "protected api, only admin can access";
    }
}

任何我的index.php

<?php
require_once 'vendor/restler.php';
use Luracast\Restler\Restler;

$r = new Restler();
$r->addAPIClass('Api', '');
$r->addAuthenticationClass('BasicAuthentication');
$r->handle();
?>

当我导航到我的网页时,会显示标准的登录和密码表单,但即使我输入了正确的用户名和密码,也不会发生任何事情——登录窗口会重新打开。

我可能犯了一些愚蠢的错误,但我找不到。这是我第一次尝试基本身份验证,所以请耐心等待。

我需要在服务器上进行一些特殊配置吗?

编辑:
看起来我需要一些特殊的配置,因为我的服务器以CGI/FastCGI的方式运行。
我已尝试从此注释添加代码: http://php.net/manual/en/features.http-auth.php#106285 但我无法正确配置.htaccess。
这是默认的Restler htaccess文件:

Options -MultiViews
DirectoryIndex index.php
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^$ index.php [QSA,L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php [QSA,L]
</IfModule>
<IfModule mod_php5.c>
    php_flag display_errors Off
</IfModule>

并且这些行是从上一个链接到工作的变通方法所需要的:

RewriteEngine on
RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization},last]

如何将两者结合起来?

我不知道为什么,但我必须执行 iUseAuthentication 在我的 BasicAuthentication 班(文档中没有任何关于它的内容,可能是因为这是RC版本,文档和示例都被修改了)。
就这样,一切都开始运转了。
我也这样修改了htaccess:

Options -MultiViews
DirectoryIndex index.php
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^$ index.php [QSA,L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php [QSA,L]
    RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization},last]
</IfModule>
<IfModule mod_php5.c>
    php_flag display_errors Off
</IfModule>

希望这能帮助到某人:)

我已经找到了我的代码,并将其发布在这里,也许有人会觉得它很有用。

<?php
use \Luracast\Restler\iAuthenticate;
use \Luracast\Restler\Resources;
class BasicAuthentication implements iAuthenticate
{
    const REALM = 'Restricted API';
    public static $requires = 'user';
    public static $role = 'user';

    public function __isAllowed()
    {
        //set http auth headers for apache+php-cgi work around
        if (isset($_SERVER['HTTP_AUTHORIZATION']) && preg_match('/Basic\s+(.*)$/i', $_SERVER['HTTP_AUTHORIZATION'], $matches))
        {
            list($name, $password) = explode(':', base64_decode($matches[1]));
            $_SERVER['PHP_AUTH_USER'] = strip_tags($name);
            $_SERVER['PHP_AUTH_PW'] = strip_tags($password);
        }

        //set http auth headers for apache+php-cgi work around if variable gets renamed by apache
        if (isset($_SERVER['REDIRECT_HTTP_AUTHORIZATION']) && preg_match('/Basic\s+(.*)$/i', $_SERVER['REDIRECT_HTTP_AUTHORIZATION'], $matches))
        {
            list($name, $password) = explode(':', base64_decode($matches[1]));
            $_SERVER['PHP_AUTH_USER'] = strip_tags($name);
            $_SERVER['PHP_AUTH_PW'] = strip_tags($password);
        }
        if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
        {
            $user = $_SERVER['PHP_AUTH_USER'];
            $pass = $_SERVER['PHP_AUTH_PW'];

            $roles = array('12345' => 'user', '67890' => 'admin');

            if (!isset($pass) || !array_key_exists($pass, $roles))
            {
                return false;
            }

            static ::$role = $roles[$pass];
            Resources::$accessControlFunction = 'BasicAuthentication::verifyAccess';
            $x = static ::$requires == static ::$role || static ::$role == 'admin';

                        $file = 'a.txt';
            $current = file_get_contents($file);
            $current .= static ::$requires." ".static::$role . "\n";
            file_put_contents($file, $current);

            return $x;
        }
        header('WWW-Authenticate: Basic realm="' . self::REALM . '"');
        throw new RestException(401, 'Basic Authentication Required');
    }

    /**
     * @access private
     */
    public static function verifyAccess(array $m)
    {
        $requires = isset($m['class']['BasicAuthentication']['properties']['requires']) ? $m['class']['BasicAuthentication']['properties']['requires'] : false;

                                $file = 'a.txt';
            $current = file_get_contents($file);
            $current .= $requires." - ".static::$role . "\n";
            file_put_contents($file, $current);
        return $requires ? static ::$role == 'admin' || static ::$role == $requires : true;
    }
}
?>

以及我的示例API类:

<?php
class Api implements iUseAuthentication
{
    private $_authenticated = false;
    /**
     * This method will be called first for filter classes and api classes so
     * that they can respond accordingly for filer method call and api method
     * calls
     *
     *
     * @param bool $isAuthenticated passes true when the authentication is
     *                              done, false otherwise
     *
     * @return mixed
     */
    public function __setAuthenticationStatus($isAuthenticated = false)
    {
        $this->_authenticated = $isAuthenticated;
    }

    /**
     * @access protected
     * @class  BasicAuthentication {@requires user}
     */
    public function user()
    {
        return "protected api, only user and admin can access";
    }
    /**
     * @access protected
     * @class  BasicAuthentication {@requires admin}
     */
    public function admin()
    {
        return "protected api, only admin can access";
    }
}
?>
