带有 PHP 的 Lametric 和 Spotify api

Question

我想创建一个应用程序，可以将 spotify 上播放的曲目发送到我的 LAMETRIC 时钟 我在 Github 上找到了一些很好的代码，我尝试调试它们，但我卡住了……你能帮我解决吗？？？

代码有效，我被困在一个返回值（空）的循环中，但它没有返回那个值

https://github.com/WilliamVenner/LaMetric-Spotify 这里是代码...

我在 spotify web 上创建了我的应用程序，我得到了我的客户 ID 和我的秘密，并且我准备好使用...... 我在 lametric dev 上创建我的应用程序：它已启动并正在运行 我在这里部署我的应用程序：https://c2x-services.com/lametric/currently_playing.php?show-artist=0&show-paused=0 可以访问

    }
    $headers = getallheaders();
    
    if (!isset($headers["Authorization"])) {
        output("X"); return;

    output($s);
    
?>

if (!isset($result["item"])) {
        output("[X]"); return;
    }

这个返回“null”

<?php
    
    class Spotify {
        
        private $auth;
        
        public function __construct($auth) {
            $this -> auth = $auth;
        }
        
        public function API($url, $post = false, $json = false) {
            
            if (!isset($this -> auth)) {
                throw new Exception('No authentication provided.');
                return;
            }
            
            $ch = curl_init();
            
            curl_setopt($ch, CURLOPT_URL, "https://accounts.spotify.com/authorize/$url");

            else
                curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
            
            curl_setopt($ch, CURLOPT_HTTPHEADER, ['Authorization: ' . $this -> auth]);
            
            $result = curl_exec($ch);
            curl_close($ch);

        }
        
    }
    

?>
