问题是我无法使用 php curl 获取所有顺序请求标头。Curl只返回最后一个请求的 headers。请检查下面的php代码：

$curl = curl_init('http://yandex.com');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_VERBOSE, true);
curl_setopt($curl, CURLOPT_COOKIEFILE, '');
curl_setopt($curl, CURLOPT_HEADER, true); //include the header in the output
curl_setopt($curl, CURLINFO_HEADER_OUT, true); //track the handle's request str
curl_setopt($curl, CURLOPT_NOBODY, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curl, CURLOPT_TIMEOUT, 5); //seconds

$requestHeaders = array("Connection: keep-alive", //we want to look like real browser
    "Cache-Control: max-age=0",
    "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
    "User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36",
    "Dnt: 1",
    "Accept-Encoding: gzip, deflate, sdch",
    "Accept-Language: ru,en-US;q=0.8,en;q=0.6,uk;q=0.4,tr;q=0.2"
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $requestHeaders);

$response = curl_exec($curl);
$info = curl_getinfo($curl);

echo 'Redirect count = ' . $info['redirect_count'] . "\n\n<br /><br />";
echo "Request header\n<br />" . str_replace("\n", "\n<br />", $info['request_header']) . "\n\n<br /><br />";
echo "Response headers\n<br />" . str_replace("\n", "\n<br />", substr($response, 0, intval($info['header_size']))) . "\n\n<br /><br />";

此代码仅显示最后一个请求标头：

HEAD / HTTP/1.1
Host: www.yandex.com
Cookie: yandexuid=1858417061425447211
Connection: keep-alive
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36
Dnt: 1
Accept-Encoding: gzip, deflate, sdch
Accept-Language: ru,en-US;q=0.8,en;q=0.6,uk;q=0.4,tr;q=0.2

但是所有三个http响应：

通过 cURL 方法无法做到这一点。唯一的方法是手动处理重定向。像这样的东西：

$a_options = array(
    CURLOPT_NOBODY => false,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_BINARYTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_FOLLOWLOCATION => false,
    CURLOPT_VERBOSE => true,
    CURLOPT_HEADER => true,
    CURLINFO_HEADER_OUT => true,
    CURLOPT_TIMEOUT => 5,
    CURLOPT_COOKIEFILE => '',
    CURLOPT_HTTPHEADER => array(
        ...
    ),
);
$a_headers = array();
$url = 'http://yandex.com';
$url_ref = '';
$ch = curl_init();
$count = 0;
for ($count = 0; $url; $count++) {
    $a_options[CURLOPT_URL] = $url;
    if ($url_ref) $a_options[CURLOPT_REFERER] = $url_ref;
    curl_setopt_array($ch, $a_options);
    $response = curl_exec($ch);
    $a_info = curl_getinfo($ch);
    $header = substr($response, 0, $i = $a_info['header_size']);
    $response = substr($response, $i);
    $a_headers[] = array(
        'request' => $a_info['request_header'],
        'response' => $header
    );
    $url_ref = $url;
    $url = '';
    if ($a_info['http_code'] == 302 && 
        preg_match('/\nlocation:\s*(\S+)\s/i', $header, $arr)) {
        $url = $arr[1];
    }
}

echo "Redirect count = $count\n\n";
echo "Headers:\n" . print_r($a_headers, true) . "\n\n";
