为什么在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

第二个链接旨在保持访问后第一个链接中存储的相同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 ";

可以紧密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之后

$ch = curl_init();
curl_setopt($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);

另外，对于访问第二个链接的curl调用，我将以下行添加到下面curl_setopt($ch, CURLOPT_HEADER ,1);以设置我之前制作的Cookie，

curl_setopt($ch2, CURLOPT_COOKIE,$formattedCookies);

但是，结果却大不相同。

在第一个链接中，标头结果curl_exec($ch2)如下：

HTTP/1.1 302 Found

而在第二个链接中，结果是这样的：

HTTP/1.1 302 Found
Date: Mon, 09 Mar 2015 00:01:19 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET

Content-Length: 16335

如您所见，Set-Cookie和Location之间存在很大的差异，在第二个链接卷曲结果中，该Location变成了一个错误页面，而标头的第一部分不存在set-cookie。

我想知道我在哪里做错了？
