不下载图片，只判断是否存在
我是这样用的
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_NOBODY, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
$result = curl_exec($curl);
$found = false;
if($result !== false) {

$statusCode = curl_getinfo($curl, CURLINFO_HTTP_CODE); if ($statusCode == 200) { $found = true; }

}
curl_close($curl);
可是对https的图片链接$statusCode一直是404
