为什么php curl不保存cookie在我的cookiefile？ [英] Why php curl does not save cookie in my cookiefile?

问题描述

我试图在curl cookiejar中保存一个cookie。我已经简化了我的代码，但它不工作。

I'm trying to save a cookie in the curl cookiejar. I've simplified my code but its not working.

<?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

setcookie.php

<?php 
$value = 'something from somewhere';
setcookie("TestCookie", $value);

?>

收到标题

HTTP / 1.1 200 OK日期：Thu，10 Oct 2013 12:10:37 GMT服务器：
Apache / 2.4.4（Win64）PHP / 5.4.12 X-Powered-By：PHP / 5.4。 12 Set-Cookie：
TestCookie = something + from + somewhere Content-Length：0 Content-Type：
text / html

HTTP/1.1 200 OK Date: Thu, 10 Oct 2013 12:10:37 GMT Server: Apache/2.4.4 (Win64) PHP/5.4.12 X-Powered-By: PHP/5.4.12 Set-Cookie: TestCookie=something+from+somewhere Content-Length: 0 Content-Type: text/html

所以testcookie是在标题，但我cookverile保持空。我做错了什么？我可以尝试使这个例子工作吗？谢谢！

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!

推荐答案

当设置 CURLOPT_COOKIEJAR 时，绝对路径。您可以使用以下命令轻松完成此操作：

When setting CURLOPT_COOKIEJAR, you need to use an absolute path. You can do this easily by using:

curl_setopt ($ch, CURLOPT_COOKIEJAR, realpath($cookie_file) );

参考：无法在cURL PHP 中使用Cookie

Reference: cannot use cookies in cURL PHP
