为什么 php 中 curl 调用后 set-cookie 的区别

>我有两页

http：//site.aspx？page=AddressData2&AddressID=298587,466579,66052

http：//site.aspx？page=AddressData2&ShowPanel=EID

第二个链接旨在维护访问后存储在第一个链接中的相同cookie/会话信息。

我通过以下方式存储了第一个cookie：

$cookies    =array(
        $cookies[0]=>$cookies[1],
        "__utma"=>"250300755.603693956.1425821004.1425827777.1425854702.4",
        "__utmb"=>"250300755",
        "__utmc"=>"250300755",
        "__utmz"=>"250300755.1425821004.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none)",
        "style"=>"A--"
);
$formattedCookies='';
foreach ($cookies as $key => $value) {
    $formattedCookies.=$key."=".$value."; ";
}
$formattedCookies   .=" path=/; HttpOnly ";

它密切模拟您将在浏览器的 Cookie 存储中获得的相同 Cookie。

但是，在我以与第一个链接相同的方式访问第二个链接后

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER  ,1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; rv:11.0) Gecko/20100101 Firefox/11.0');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url_search);
// Execute
$result=curl_exec($ch);

并且仅在另外，对于访问第二个链接的 curl 调用，我在 curl_setopt($ch, CURLOPT_HEADER ,1); 下添加此行以设置我之前制作的 cookie，

curl_setopt($ch2, CURLOPT_COOKIE,$formattedCookies);

然而，结果却大不相同。

在第一个链接中，curl_exec($ch2)的标头结果如下所示：

而在第二个链接中，结果如下所示：

如您所见，Set-Cookie 和 Location 之间存在很大差异，在第二个链接卷曲结果中，该位置成为错误页面，而标头的第一部分不存在 set-cookie。
