PHP cURL：读取特定的响应头 [英] PHP cURL: Read a specific response header

问题描述

我在PHP中使用cURL来POST到创建资源的端点。它返回201响应，其Location标题给出了创建的资源的URL。我还在响应正文中获得了一些信息。

I am using cURL in PHP to POST to an endpoint that is creating a resource. It returns a 201 response with a Location header giving the URL of the resource created. I also get some information in the body of the response.

获取响应的纯文本正文的最佳方法是什么，并获取位置的值头？ curl_getinfo没有返回那个标题，当我这样做时：

What's the best way to get the plain-text body of the response, and also get the value of the location header? curl_getinfo doesn't return that header, and when I do this:

    curl_setopt($ch, CURLOPT_HEADERFUNCTION, function($ch, $header) {
        var_dump($header);
    });

我只看到一个标题被转出 - HTTP / 1.1 201 Created响应代码。

I only see one header dumped out--the "HTTP/1.1 201 Created" response code.

推荐答案

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'http://www.google.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER,true);

$result = curl_exec($ch);

curl_close($ch);

list($headers, $content) = explode("\r\n\r\n",$result,2);

// Print header
foreach (explode("\r\n",$headers) as $hdr)
    printf('<p>Header: %s</p>', $hdr);

// Print Content
echo $content;
