How do I pass cookies on a CURL redirect?
提问by acme
imagine the following scenario: I open a CURL connection and pass some XML-Logindata via POST. The server answers with an 302 redirect, where the session cookies are set and redirects me to a following "welcome"-page. If I enable FOLLOWLOCATION the cookies set on the redirection-page get lost and the welcome-page fails with a "session expired"-message. If I disable FOLLOWLOCATION, I'm not redirected (obviously) and get a HTML-page with "the page has moved to another location" with a link that leads me to the welcome-page. This works as the cookies are set, but I need to follow the redirect and go straight to the welcome-page.
想象以下场景：我打开一个 CURL 连接并通过 POST 传递一些 XML-Logindata。服务器以 302 重定向进行响应，其中设置了会话 cookie 并将我重定向到以下“欢迎”页面。如果我启用 FOLLOWLOCATION，重定向页面上设置的 cookie 会丢失，欢迎页面失败并显示“会话已过期”消息。如果我禁用 FOLLOWLOCATION，我不会被重定向（显然）并获得一个带有“页面已移动到另一个位置”的 HTML 页面，其中包含一个将我引导到欢迎页面的链接。这在设置 cookie 时起作用，但我需要遵循重定向并直接转到欢迎页面。
So, how do I maintain the cookies so that they are set correctly?
那么，我如何维护 cookie 以便正确设置它们？
This is my code so far:
到目前为止，这是我的代码：
$ch = curl_init('https://www.example.com/login');
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, '<some xml data>');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml; charset=UTF-8"));
curl_exec($ch);
curl_close($ch)
Thanks for any help! ;
谢谢你的帮助！;

This is an old question, but I had the same problem, so google took me here. Finally, I managed to solve it. By passing an empty string "" to set CURLOPT_COOKIEFILE using curl_setopt will solve the problem:
这是一个老问题，但我遇到了同样的问题，所以谷歌把我带到了这里。最后，我设法解决了它。通过使用 curl_setopt 传递一个空字符串 "" 来设置 CURLOPT_COOKIEFILE 将解决问题：
curl_setopt($ch, CURLOPT_COOKIEFILE, "");
See section CURLOPT_COOKIEFILEof http://curl.haxx.se/libcurl/c/curl_easy_setopt.html
见CURLOPT_COOKIEFILE的http://curl.haxx.se/libcurl/c/curl_easy_setopt.html

to instruct php on curl session to use cookies you should set two options:
要在 curl 会话中指示 php 使用 cookie，您应该设置两个选项：
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');// set where cookies will be stored
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');// from where it will get cookies
so every cookie will be appended on CURLOPT_COOKIEJAR and those cookie will be carried on every location by setting CURLOPT_COOKIEFILE
所以每个 cookie 都会被附加到 CURLOPT_COOKIEJAR 上，并且这些 cookie 将通过设置 CURLOPT_COOKIEFILE 被携带到每个位置

To answer myself, this is how I did it:
为了回答自己，我是这样做的：
Grab the header-http-status code. If it's redirect then extract the new location and redirect manually. Otherwise remove the header and output the contents:
获取 header-http-status 代码。如果是重定向，则提取新位置并手动重定向。否则删除标题并输出内容：
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
if($info['http_code'] == 301 || $info['http_code'] == 302) { // redirect manually, cookies must be set, which curl does not itself
// extract new location
preg_match_all('|Location: (.*)\n|U', $response, $results);
$location = implode(';', $results[1]);
// redirect manually
header("Location: $location");
exit;
} else { // no redirect, remove header and output directly
$response = substr_replace($response, '', 0, strpos($response, '<', 0));
echo $response;
}
