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

问题描述

我想得到回应&来自CURL的响应头使用PHP，专门用于Content-Disposition：attachment;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。

我已经尝试使用HeaderFunction调用一个函数来读取额外的标题，但是，我无法添加

下面是我的代码的一部分，它是一个Curl包装类：

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

解决方案

：

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

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.

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.

Does anyone have any ideas please?

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);
 }

解决方案

Here, this should do it:

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, "\r\n\r\n"));

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

            $headers[$key] = $value;
        }

    return $headers;
}
