YouTube的PHP Curl从服务器和本地主机返回不同的结果

Question

我正在尝试使用php中的curl通过以下代码向YouTube发出GET请求。

    $ch = curl_init($url);

    curl_setopt($ch, CURLOPT_USERAGENT, $this->user_agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $this->cookie_file);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $this->cookie_file);

    if ($this->proxy) {
        curl_setopt($ch, CURLOPT_PROXY, $this->proxy);
    }

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

    // debug info
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    $verbose = fopen(storage_path()."/logs/tmp", 'w');
    curl_setopt($ch, CURLOPT_STDERR, $verbose);

    $result = curl_exec($ch);
    curl_close($ch);

    return $result;

该请求在服务器上按预期工作，但是当我在localhost上运行此代码时，得到的结果不同（格式不同）。

以下是$ ch的输出；

服务器的$ ch（PHP：7.2.24，cURL：7.58.0，Ubuntu）

我不知道为什么结果格式不同，如何获得与本地主机上的服务器相同的结果？
