php - curl如何判断https图片是否存在

Question

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

Answer 1

试试

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false) 

判断下返回的东西是否404

$contents = curl_exec($ch);

if(preg_match("/404/", $contents)){
    return false;
}else{
    return true;
}

Answer 2

可以用get_headers啊

<?php
$url='https://ss0.bdstatic.com/5aV1bjqh_Q23odCf/static/superman/img/logo/bd_logo1_31bdc765.png';
print_r(get_headers($url));

Answer 3

head方式请求

Answer 4

模拟请求一下，看看是不是200
