卷毛-检索标头-空响应 [英] Curl - Retrieve headers - empty response

问题描述

在使用curl时使用php。

Using php when working with curl.

我试图只接收标头。

我从以下网址请求： http://halens.se / kvinna-klader-bad-strand-baddrakter-93 / baddrakt-074209 /

我的设置如下：

  CURLOPT_AUTOREFERER     => true,
  CURLOPT_CERTINFO        => false,
  CURLOPT_CRLF            => true,
  CURLOPT_CONNECTTIMEOUT  => 15,
  CURLOPT_FAILONERROR     => true,
  CURLOPT_FOLLOWLOCATION  => true,
  CURLOPT_FORBID_REUSE    => true,
  CURLOPT_FRESH_CONNECT   => true,
  CURLOPT_HEADER          => true,
  CURLOPT_MAXREDIRS       => 15,
  CURLOPT_PROTOCOLS       => CURLPROTO_HTTP,
  CURLOPT_REDIR_PROTOCOLS => CURLPROTO_HTTP,
  CURLOPT_RETURNTRANSFER  => true,
  CURLOPT_SSL_VERIFYPEER  => false,
  CURLOPT_TIMEOUT         => 15,
  CURLOPT_HEADER          => true,
  CURLOPT_NOBODY          => true

但是响应为空。.我做错了什么？或我们如何以其他方式解决此问题？

如果我改了最后一个设置为：

If I instead change the last setting to:

  CURLOPT_NOBODY          => false

然后我得到标题：

推荐答案

对于具体问题没有答案：似乎有点奇怪和谷歌搜索我可以看到其他人也在这个问题上苦苦挣扎（没有进一步解释）-但是您是否知道 get_headers 函数？

Not an answer to the specific : It seems a little bit weird and googling around I can see other people have struggling with this issue also (without getting closer to an explanation) - but are you aware of the get_headers function?

$header = get_headers('http://halens.se/kvinna-klader-bad-strand-baddrakter-93/baddrakt-074209/');
echo '<pre>';
print_r($header);
echo '</pre>';

输出
