使用 Curl 将标头作为数组返回 [英] Returning header as array using Curl

问题描述

我正在尝试获得响应 &来自使用 PHP 的 CURL 的响应标头，专门用于 Content-Disposition:附件；所以我可以返回在标题中传递的文件名.这似乎没有在 curl_getinfo 中返回.

I'm trying to get the response & the response headers from CURL using PHP, specifically for Content-Disposition: attachment; so I can return the filename passed within the header. This doesn't seem to get returned within curl_getinfo.

我已尝试使用 HeaderFunction 调用函数来读取附加标头，但是，我无法将内容添加到数组中.

I've tried using the HeaderFunction to call a function to read the additional headers, however, I am unable to add the contents to an array.

请问大家有什么想法吗?

Does anyone have any ideas please?

下面是我的代码的一部分，它是一个 Curl 包装类:

Below is part of my code which is a Curl wrapper class:

 ...
 curl_setopt($this->_ch, CURLOPT_URL, $this->_url);
 curl_setopt($this->_ch, CURLOPT_HEADER, false);
 curl_setopt($this->_ch, CURLOPT_POST, 1);
 curl_setopt($this->_ch, CURLOPT_POSTFIELDS, $this->_postData);
 curl_setopt($this->_ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($this->_ch, CURLOPT_USERAGENT, $this->_userAgent);
 curl_setopt($this->_ch, CURLOPT_HEADERFUNCTION, 'readHeader');

 $this->_response = curl_exec($this->_ch);
 $info = curl_getinfo($this->_ch);
 ...


 function readHeader($ch, $header)
 {
      array_push($this->_headers, $header);
 }

推荐答案

这里应该这样做:

curl_setopt($this->_ch, CURLOPT_URL, $this->_url);
curl_setopt($this->_ch, CURLOPT_HEADER, 1);
curl_setopt($this->_ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($this->_ch);
$info = curl_getinfo($this->_ch);

$headers = get_headers_from_curl_response($response);

function get_headers_from_curl_response($response)
{
    $headers = array();

    $header_text = substr($response, 0, strpos($response, "

"));

    foreach (explode("
", $header_text) as $i => $line)
        if ($i === 0)
            $headers['http_code'] = $line;
        else
        {
            list ($key, $value) = explode(': ', $line);

            $headers[$key] = $value;
        }

    return $headers;
}
