问题是我无法使用php-ccurl获取所有顺序请求头。Curl只返回最后一个请求的头。请检查以下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 />";
此代码只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：

检查
- win8.1、php5.5.9x86、apachex86、curl 7.30.0
- Linux 2.6.32，PHP 5.4.32，curl 7.19.7
通过cURL的方式无法做到这一点。唯一的方法是手动处理重定向。类似这样的东西：
$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";
