调用未定义函数 apache_request_headers Slim 框架

Question

我发这篇文章是因为 none 其他帖子帮助解决了我的问题。我在 chrome 上使用 slim and advanced rest api 应用程序进行测试。我在网上尝试了很多建议，但没有任何效果。我在 hostgator 上的运行 php 5.5。通过授权 header 时出现错误：

call to undefined function apache_request_headers()

  <?php

require_once '../include/DbHandler.php';
require_once '../include/PassHash.php';
require '.././libs/Slim/Slim.php';

\Slim\Slim::registerAutoloader();

$app = new \Slim\Slim();


// User id from db - Global Variable
$user_id = NULL;


function authenticate(\Slim\Route $route) {
    // Getting request headers
    $headers = apache_request_headers();
    $response = array();
    $app = \Slim\Slim::getInstance();

    // Verifying Authorization Header
    if (isset($headers['Authorization'])) {
        $db = new DbHandler();

        // get the api key
        $api_key = $headers['Authorization'];
        // validating api key
        if (!$db->isValidApiKey($api_key)) {
            // api key is not present in users table
            $response["error"] = true;
            $response["message"] = "Access Denied. Invalid Api key";
            echoRespnse(401, $response);
            $app->stop();
        } else {
            global $user_id;
            // get user primary key id
            $user_id = $db->getUserId($api_key);
        }
    } else {
        // api key is missing in header
        $response["error"] = true;
        $response["message"] = "Api key is misssing";
        echoRespnse(400, $response); 
        //echoRespnse(400, $headers);

        $app->stop();
    }
}

.htaccess

RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule ^(.*)$ %{ENV:BASE}index.php [QSA,L]
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=

PHP 5.4.0 及更高版本支持 apache_request_headers()。但是还有其他解决方案，例如下面的代码来自：http://php.net/manual/en/function.apache-request-headers.php

function apache_request_headers() {
  $arh = array();
  $rx_http = '/\AHTTP_/';
  foreach($_SERVER as $key => $val) {
    if( preg_match($rx_http, $key) ) {
      $arh_key = preg_replace($rx_http, '', $key);
      $rx_matches = array();
      // do some nasty string manipulations to restore the original letter case
      // this should work in most cases
      $rx_matches = explode('_', $arh_key);
      if( count($rx_matches) > 0 and strlen($arh_key) > 2 ) {
        foreach($rx_matches as $ak_key => $ak_val) $rx_matches[$ak_key] = ucfirst($ak_val);
        $arh_key = implode('-', $rx_matches);
      }
      $arh[$arh_key] = $val;
    }
  }
  return( $arh );
}

正在更新，这似乎解决了 header 问题

   if (!function_exists('apache_request_headers')) { 


       function apache_request_headers() { 
            foreach($_SERVER as $key=>$value) { 
                if (substr($key,0,5)=="HTTP_") { 
                    $key=str_replace(" ","-",ucwords(strtolower(str_replace("_"," ",substr($key,5))))); 
                    $out[$key]=$value; 
                }else{ 
                    $out[$key]=$value; 
        } 
            } 
            return $out; 
        } 
}
