php使用curl下载https资源文件如何实现?

https

代码如下:

$url = 'https://www.xxx.com/xxx.mp3';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);

var_dump(curl_error($ch));


提示错误:SSL: certificate verification failed (result: 5)

然后网上搜了一大片：最多的解决方法是加上如下代码:

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

加上之后又报错：

SSL: CA certificate set, but certificate verification is disabled

请问如何解决？？？？

随便他们好了

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

可用吧，平常这样没出现问题啊

百度https这样可以，你要爬那个地址

<?php

$url = 'https://www.baidu.com/';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$output = curl_exec($ch);
if (!$output) {
    echo curl_error($ch);
} else {
    var_dump($output);
}

?>

闹闹依旧不闹

补充代码＝_＝

<?php
$urls = [
    "https://cdn.pixabay.com/photo/2017/01/28/21/48/lion-2016620__340.jpg 1x, https://cdn.pixabay.com/photo/2017/01/28/21/48/lion-2016620__480.jpg",
    "https://cdn.pixabay.com/photo/2017/02/20/19/29/architecture-2083687__340.jpg 1x, https://cdn.pixabay.com/photo/2017/02/20/19/29/architecture-2083687__480.jpg",
    "https://cdn.pixabay.com/photo/2017/02/06/12/34/reptile-2042906__340.jpg 1x, https://cdn.pixabay.com/photo/2017/02/06/12/34/reptile-2042906__480.jpg"
];

foreach ($urls as $k => $v) {
     if (!empty($v) && preg_match("~^http~i", $v)) {
        $nurl[$k] = trim(str_replace(' ', "%20", $v));
        $curl[$k] = curl_init($nurl[$k]);
        curl_setopt($curl[$k], CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
        curl_setopt($curl[$k], CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl[$k], CURLOPT_HEADER, 0);
        curl_setopt($curl[$k], CURLOPT_CONNECTTIMEOUT, 20);
        curl_setopt($curl[$k], CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl[$k], CURLOPT_SSL_VERIFYHOST, false);        
        if (!isset($handle)) {
           $handle = curl_multi_init();
        }
        curl_multi_add_handle($handle, $curl[$k]);
      }
      continue;
}
$active = null;
do {
   $mrc = @curl_multi_exec($handle, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
   while ($active && $mrc == CURLM_OK) {
       if (curl_multi_select($handle) != -1) {
          do {
             $mrc = curl_multi_exec($handle, $active);
          } while ($mrc == CURLM_CALL_MULTI_PERFORM);
       }
   }

foreach ($curl as $k => $v) {
   var_dump(curl_error($curl[$k]));
}

会有报错：

SSL: CA certificate set, but certificate verification is disabled

已解决

curl_setopt($curl[$k], CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

改成：

curl_setopt($curl[$k], CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V6);

就可以了。
