Question

嘿，我现在一直在寻找解决问题的方法，但到目前为止还没有运气......基本上，我想在PHP中使用curl来下载页面内容。以下是代码

  static function getContent($url) {
    // pull down the content that the url pointing to 
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_VERBOSE, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); 
    curl_setopt($curl, CURLOPT_AUTOREFERER, true);
    curl_setopt($curl, CURLOPT_USERAGENT, Constants::$USER_AGENT_CHROME);
    $cookie = realpath(Constants::$ROOT_DIR . Constants::$COOKIE);
    curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);
    curl_setopt($curl, CURLOPT_FAILONERROR, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
    // curl_setopt ($curl, CURLOPT_CAINFO, dirname(__FILE__).'/cacert.pem');
    $content = curl_exec($curl);
    curl_close($curl);
    return $content;
  }

使用以下url对函数的调用总是返回空内容，到目前为止，我尝试过的其他不同网址（来自不同的域）没有问题。

$ url ='https://www.etsy.com/listing/150723421/iretrofone-20-steampunk-silver';

有什么理由？

[编辑]我在亚马逊Linux上运行此脚本，机器上可能缺少某些内容，以致问题暴露无遗。到目前为止，这两个答案对我不起作用。

[编辑]以下是curl_getinfo输出
