PHP cURL在单个请求中检索响应标头和正文？ [英] PHP cURL retrieving response headers AND body in a single request?

问题描述

有没有办法使用PHP获取cURL请求的标题和正文？我发现这个选项：

Is there any way to get both headers and body for a cURL request using PHP? I found that this option:

curl_setopt($ch, CURLOPT_HEADER, true);

将返回正文加标题，但是我需要解析它得到的身体。

is going to return body plus headers, but then i need to parse it to get the body. Any way to get both in a more usable (and secure) way?

EDIT ：对于单个请求，我指的是发出一个HEAD

EDIT: for "single request" i mean avoind issuing a HEAD request prior of GET/POST.

推荐答案

有。详情请参阅在PHP文档中发布： http://www.php.net/manual/en/ function.curl-exec.php＃80442

Yes. For details, please take a look at this post in the PHP documentation: http://www.php.net/manual/en/function.curl-exec.php#80442

代码示例：

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
// ...

$response = curl_exec($ch);

// Then, after your curl_exec call:
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);
