检查头对Restler API框架授权 [英] check header Authorization on Restler API framework

问题描述

我要扩展Restler检查，如果自定义标题授权的有效值传递。我有在周围的修复越来越麻烦，我想这一点，但没有机会：

 类AuthenticateMe实现IAuthenticate进行（）{功能__isAuthenticated（）{
    //返回使用isset（$ _ SERVER ['HTTP_AUTH_KEY']）及＆放大器; $ _ SERVER ['HTTP_AUTH_KEY'] == AuthenticateMe :: KEY？真假;
    $头= apache_request_headers（）;
    的foreach（$标题，如$头=＆GT; $值）{
        如果（$头==授权）{
            返回TRUE;
        }其他{
            //返回FALSE;
            抛出新RestException（404）;
        }
    }
}
}
 

解决方案

让我很快地解决您的自定义AUTH头示例

 类HeaderAuth实现IAuthenticate进行{
    功能__isAuthenticated（）{
        //我们只是在寻找所谓的验证自定义标题
        //但$ _ SERVER prepends HTTP_并使其全部大写
        //这就是为什么我们需要寻找'HTTP_AUTH，而不是
        //也不要用头'授权'。不是这样
        //包含在PHP的$ _ SERVER变量
        返回使用isset（$ _ SERVER ['HTTP_AUTH']）及＆放大器; $ _ SERVER ['HTTP_AUTH'] =='密码';
    }
}
 

我测试，以确保它的作品！

下面是如何使它与工作的授权的头，它只能在Apache服务器

 类授权实现IAuthenticate进行{
    功能__isAuthenticated（）{
        $头= apache_request_headers（）;
        返回使用isset（$头['授权']）及＆放大器; $头['授权'] =='密码';
    }
}
 

我想通了，PHP 授权头转换成 $ _ SERVER ['PHP_AUTH_DIGEST'] 或 $ _ SERVER ['PHP_AUTH_USER'] 和 $ _ SERVER ['PHP_AUTH_PW'] 根据AUTH请求的类型（摘要或基本）我们可以使用下面的的.htaccess 文件以启用 $ _ SERVER ['HTTP_AUTHORIZATION'] 头

的DirectoryIndex index.php文件

 的DirectoryIndex index.php文件
＆LT; IfModule mod_rewrite.c＆GT;
    RewriteEngine叙述在
    重写规则^ $的index.php [QSA，L]
    的RewriteCond％{} REQUEST_FILENAME！-f
    的RewriteCond％{} REQUEST_FILENAME！-d
    重写规则^（。*）$的index.php [QSA，L]
    。重写规则*  -  [ENV = HTTP_AUTHORIZATION：％{HTTP：授权}，最后]
＆LT; / IfModule＆GT;
 

重要的部分就是重写规则* - [ENV = HTTP_AUTHORIZATION：％{HTTP：授权}，最后]

现在我们的例子可以被简化为：

 类授权实现IAuthenticate进行{
    功能__isAuthenticated（）{
        返回使用isset（$ _ SERVER ['HTTP_AUTHORIZATION']）及＆放大器; $ _ SERVER ['HTTP_AUTHORIZATION'] =='密码';
    }
}
 

I want to extend Restler to check if a valid value of custom header Authorization was passed. I am having trouble in getting around the fix, I tried this, but no chance:

class AuthenticateMe implements iAuthenticate() {

function __isAuthenticated() {
    //return isset($_SERVER['HTTP_AUTH_KEY']) && $_SERVER['HTTP_AUTH_KEY']==AuthenticateMe::KEY ? TRUE : FALSE;
    $headers = apache_request_headers();
    foreach ($headers as $header => $value) {
        if($header == "Authorization") {
            return TRUE;
        } else {
            //return FALSE;
            throw new RestException(404);
        }
    }
}
}

解决方案

Let me quickly fix your custom auth header example

class HeaderAuth implements iAuthenticate{
    function __isAuthenticated(){
        //we are only looking for a custom header called 'Auth'
        //but $_SERVER prepends HTTP_ and makes it all uppercase
        //thats why we need to look for 'HTTP_AUTH' instead
        //also do not use header 'Authorization'. It is not
        //included in PHP's $_SERVER variable
        return isset($_SERVER['HTTP_AUTH']) && $_SERVER['HTTP_AUTH']=='password';
    }
}

I have tested it to make sure it works!

Here is how to make it work with Authorization header, it works only on apache servers

 class Authorization implements iAuthenticate{
    function __isAuthenticated(){
        $headers =  apache_request_headers();
        return isset($headers['Authorization']) && $headers['Authorization']=='password';
    }
}

I figured out that PHP converts Authorization header into $_SERVER['PHP_AUTH_DIGEST'] or $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'] depending on the type of auth request (digest or basic), we can use the following .htaccess file to enable the $_SERVER['HTTP_AUTHORIZATION'] header

DirectoryIndex index.php

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>

important part is RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization},last]

Now our example can be simplified to:

class Authorization implements iAuthenticate{
    function __isAuthenticated(){
        return isset($_SERVER['HTTP_AUTHORIZATION']) && $_SERVER['HTTP_AUTHORIZATION']=='password';
    }
}
