Question

我试图从Spotify获取一些数据，因为他们最近改变了他们的API我写了一个遵循新指令的新功能：

function get_Spotify() {
    $getTrackID = $this->db->query("SELECT `trackid` FROM `spotify` ORDER BY RAND() LIMIT 1");
    $TrackID = $getTrackID->fetch_assoc();
    $id=$TrackID['trackid'];

    $client_id = '********************'; 
    $client_secret = '**********************'; 

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,            'https://accounts.spotify.com/api/token' );
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt($ch, CURLOPT_POST,           1 );
    curl_setopt($ch, CURLOPT_POSTFIELDS,     'grant_type=client_credentials' ); 
    curl_setopt($ch, CURLOPT_HTTPHEADER,     array('Authorization: Basic '.base64_encode($client_id.':'.$client_secret))); 
    $result=curl_exec($ch); 
    $result = json_decode($result, true);
    curl_close($ch);    

    //find spotify data
    $spotifyURL = 'https://api.spotify.com/v1/tracks/'.$id;
    $authorization = 'Authorization: Bearer '.$result["access_token"];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization ));
    curl_setopt($ch, CURLOPT_URL, $spotifyURL);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:x.x.x) Gecko/20041107 Firefox/x.x");
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $json = curl_exec($ch);
    $json = json_decode($json, true);
    curl_close($ch);

    $spotifyURL_artist = $json['artists'][0]['href'];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization ));
    curl_setopt($ch, CURLOPT_URL, $spotifyURL_artist);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:x.x.x) Gecko/20041107 Firefox/x.x");
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $json_artist = curl_exec($ch);
    $data_artist = json_decode($json_artist, true);
    curl_close($ch);

    $Spotify_Player = '
    <div class="container-playerspot">
        <div class="playerspot">
            <div class="bg_spotify" style="background:url('.$data_artist['images'][0]['url'].');"><div class="ert-spotify"></div></div>
            <ul class="player_spot-info info-one">
                <li>'.$json['artists'][0]['name'].'</li>
                <li>'.$json['name'].'</li>
            </ul>
            <ul class="player_spot-info info-two">
                <li>'.$json['artists'][0]['name'].'</li>
                <li>'.$json['name'].'</li>
                <li><span id="duration"></span><i> / </i>0.30</li>
            </ul>
            <audio id="audio-player_spot" ontimeupdate="SeekBar()" ondurationchange="CreateSeekBar()" preload="none" loop>
            <source src="'.$json['preview_url'].'" type="audio/mpeg">Your browser does not support the audio element.
            </audio>
        </div>
    </div>';

    return $Spotify_Player;

}

但我的网页加载速度很慢，因此在调查使用microtime()后，我发现此功能（get_Spotify()）需要 300毫秒。

我的代码有什么问题会导致这样一个灾难性的后果吗？

P.S。

MySQL表实际上只有4个结果，所以我排除了我的查询可能的原因。

如何使用PHP cURL使用新的Spotify API？
