file_get_content 在 php 中不适用于 https

Question

有人对通过 https 的网站显示内容有疑问吗？该代码一直有效，直到服务器上的所有站点都获得 ssl。也许证书是 tlss 1.2？所以我试图从中执行此操作的站点现在拥有此证书。

$data = file_get_contents('https://www.ladygaga.com/'); 
echo $data;

Answer 1

Based on OpenSSL changes in PHP 5.6，试试这个：


$arrContextOptions=array(
    "ssl"=>array(
        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ),
);  

$response = file_get_contents("https://www.ladygaga.com/", false, stream_context_create($arrContextOptions));

echo $response;

另一种选择是这样使用 curl：

function file_get_contents_curl( $url ) {

  $ch = curl_init();

  curl_setopt( $ch, CURLOPT_AUTOREFERER, TRUE );
  curl_setopt( $ch, CURLOPT_HEADER, 0 );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt( $ch, CURLOPT_URL, $url );
  curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, TRUE );

  $data = curl_exec( $ch );
  curl_close( $ch );

  return $data;

}

$data = file_get_contents_curl("https://www.ladygaga.com");

Answer 2

根据php.net

When using SSL, Microsoft IIS will violate the protocol by closing the connection without sending a close_notify indicator. PHP will report this as "SSL: Fatal Protocol Error" when you reach the end of the data. To work around this, the value of error_reporting should be lowered to a level that does not include warnings. PHP can detect buggy IIS server software when you open the stream using the https:// wrapper and will suppress the warning. When using fsockopen() to create an ssl:// socket, the developer is responsible for detecting and suppressing this warning.
