SLIM框架路由验证v2与v3

Question

我有一个使用Slim v2构建的API，我保护某些路由通过中间件功能“authenticate”：

    /**
     * List marca novos
     * method GET
     * url /novos/marca/:idmarca
     */
    $app->get('/novos/marca/:idmarca', 'authenticate', function($idmarca) {
        $response = array();
        $db = new DbHandler('dbnovos');


        // fetching marca
        $marca = $db->getMarcaNovos($idmarca);

        $response["error"] = false;
        $response["marca"] = array();

        array_walk_recursive($marca, function(&$val) {
            $val = utf8_encode((string)$val);
        });

        array_push($response["marca"], $marca);

        echoRespnse(200, $response, "marcaoutput");
    })->via('GET', 'POST');

authenticate函数检查是否已发送标头授权值（user_api_key）并对数据库进行检查。

我正在尝试使用以下路径在Slim v3 API中获得相同的功能：

    /**
     * List marca novos
     * method GET
     * url /novos/marca/:idmarca
     */
    $app->get('/novos/marca/{idmarca}', function ($request, $response, $args) {

    $output = array();
    $db = new DbHandler('mysql-localhost');
    $marca = $db->getMarcaNovos($args['idmarca']);

    if ($marca != NULL) {
        $i = 0;
        foreach($marca as $m) {
            $output[$i]["id"] = $m['id'];
            $output[$i]["nome"] = utf8_encode($m['nome']);
            $i++;
        }

    } else {
        // unknown error occurred
        $output['error'] = true;
        $output['message'] = "An error occurred. Please try again";
    }

    // Render marca view
    echoRespnse(200, $response, $output, "marca");
})->add($auth);

这是我的中间件

/**
 * Adding Middle Layer to authenticate every request
 * Checking if the request has valid api key in the 'Authorization' header
 */
$auth = function ($request, $response, $next) {

$headers = $request->getHeaders();
$outcome = array();

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

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

};

但我总是得到错误：“这里不允许 - 缺少Api键”基本上，如果设置$ headers ['Authorization']的测试失败。什么是$ headers数组结构或如何获得通过标头传递的Authorization值？

如果您发送的内容不是有效的HTTP Basic Authorization标头，PHP将无法访问它。您可以通过将以下重写规则添加到.htaccess文件来解决此问题。

RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
