PHP - 与get_headers和SSL

Question

错误这是我的代码

$url = 'http://www.wikipedia.com'; // URL WITH HTTP 
$hurl = str_replace("http", "https", $url); // URL WITH HTTPS 

$urlheads = get_headers($url, 1); 
$surlheads = get_headers($hurl, 1);  
$urlx = false; 
$surlx = false; 

foreach ($urlheads as $name => $value) 
{ 
    if ($name === 'Location') 
    { 
     $urlx=$value; 
    } 
    else{ 

    } 
} 
print_r($urlx); 

这是错误我收到：

Warning: get_headers(): Peer certificate CN=`*.wikipedia.org' did not match expected CN=`www.wikipedia.com' in.... 

Warning: get_headers(): Failed to enable crypto in.... 

Warning: get_headers(https://www.wikipedia.com): failed to open stream:  operation failed in ..... 
Array ([0] => http://www.wikipedia.org/ [1] => https://www.wikipedia.org/) 

这是怎么回事，什么是适当的方式从中获取头https页面没有错误（没有卷曲）。此外，当我尝试了一些其他的HTTPS网站一切正常

的问题是下到服务器证书被呈现为一个通配符*所以它可以允许同一个证书下的所有子域，但出于某种奇怪的原因通配符*在SSL验证期间被逐字使用导致失败。要解决此问题，请使用stream_context_set_default()将SSL验证设置为false。

stream_context_set_default([ 
    'ssl' => [ 
     'verify_peer' => false, 
     'verify_peer_name' => false, 
    ], 
]); 

$url = 'https://www.wikipedia.com'; // URL WITH HTTPS 

$headers = get_headers($url, 1); 

var_dump($headers); 

输出
