Why php curl does not save cookie in my cookiefile?
提问by kasper Taeymans
I'm trying to save a cookie in the curl cookiejar. I've simplified my code but its not working.
我正在尝试在 curl cookiejar 中保存一个 cookie。我已经简化了我的代码，但它不起作用。
<?php
$cookie_file = './cookies.txt';
if (! file_exists($cookie_file) || ! is_writable($cookie_file)){
echo 'Cookie file missing or not writable.';
exit;
}//cookie_file is writable, so this is not the issue
$ch = curl_init (html_entity_decode("http://localhost/kiala_test/setcookie.php"));
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie_file);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
//curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$output = curl_exec ($ch);
echo $output;
?>
setcookie.php
设置cookie.php
<?php
$value = 'something from somewhere';
setcookie("TestCookie", $value);
?>
received header

so the testcookie is in the header but my cookiefile stays empty. What I'm doing wrong? what can I try to make this example work? thank you!
所以 testcookie 在标题中，但我的 cookiefile 保持为空。我做错了什么？我可以尝试什么来使这个示例工作？谢谢你！

When setting CURLOPT_COOKIEJAR, you need to use an absolute path. You can do this easily by using:
设置时CURLOPT_COOKIEJAR，需要使用绝对路径。您可以使用以下方法轻松完成此操作：
curl_setopt ($ch, CURLOPT_COOKIEJAR, realpath($cookie_file) );
Reference: cannot use cookies in cURL PHP

As referenceabout CURLOPT_COOKIEJAR:
作为参考有关CURLOPT_COOKIEJAR：
The name of a file to save all internal cookies to when the handle is closed, e.g. after a call to curl_close.
当句柄关闭时保存所有内部 cookie 的文件名，例如在调用 curl_close 之后。
So, in your code didn't used curl_close.
所以，在你的代码中没有使用curl_close.
Use curl_close($ch);after curl_exec, for save cookies in jar file.
使用curl_close($ch);after curl_exec, 将 cookie 保存在 jar 文件中。

Yes realpath works, but remember that (thanks to php.net) before second call of curl_exec, CURLOPT_COOKIEFILE should be the same as in previous setting of CURLOPT_COOKIEJAR - because it is used for reading from "jared" file :)
是的 realpath 有效，但请记住（感谢 php.net）在第二次调用 curl_exec 之前，CURLOPT_COOKIEFILE 应该与 CURLOPT_COOKIEJAR 的先前设置相同 - 因为它用于从“jared”文件中读取:)
//my working snippet for one php file:
//....
curl_setopt($ch, CURLOPT_COOKIEJAR, realpath('test2-cookie.txt'));
$content = curl_exec($ch);
curl_close($ch);
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, realpath('test2-cookie.txt'));
curl_setopt ($ch, CURLOPT_COOKIEFILE, realpath('test2-cookie.txt'));
$content = curl_exec($ch);//second call
