Reading Cookie when using Curl in php, how to?
提问by Diode
I am connecting to an API service which authenticates users using cookies. I make these two statements from command prompt and it works.
我正在连接到使用 cookie 对用户进行身份验证的 API 服务。我从命令提示符发出这两个语句并且它有效。
curl -d "u=username&p=password" -c ~/cookiejar https://domain/login
curl -b https://domain/getData
Now I want to make two equivalent php files login.phpand get_data.phpusing curl.
现在我想使用 curl制作两个等效的 php 文件login.php和get_data.php。
I am using
我在用
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
in login.php
在 login.php
and
和
curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile);
in get_data.php
在 get_data.php
It is not working. Cookie file is getting created but second curl is not reading it.
Is this the right way to do it ? Do I have to read the cookie file seperately and set the header Cookie? Any help would appreciated. Thanks.
它不工作。正在创建 Cookie 文件，但第二个 curl 没有读取它。这是正确的方法吗？我是否必须单独读取 cookie 文件并设置标题Cookie？任何帮助将不胜感激。谢谢。

This will do the trick. I run it against Google.com as an example:
这将解决问题。我以 Google.com 为例运行它：
<?PHP
// open a site with cookies
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.google.com");
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; rv:11.0) Gecko/20100101 Firefox/11.0');
curl_setopt($ch, CURLOPT_HEADER ,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER ,1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$content = curl_exec($ch);
// get cookies
$cookies = array();
preg_match_all('/Set-Cookie:(?<cookie>\s{0,}.*)$/im', $content, $cookies);
print_r($cookies['cookie']); // show harvested cookies
// basic parsing of cookie strings (just an example)
$cookieParts = array();
preg_match_all('/Set-Cookie:\s{0,}(?P<name>[^=]*)=(?P<value>[^;]*).*?expires=(?P<expires>[^;]*).*?path=(?P<path>[^;]*).*?domain=(?P<domain>[^\s;]*).*?$/im', $content, $cookieParts);
print_r($cookieParts);
?>
See other examplesfor how to effectively parse such as string.

is there any method to see the curl request headers. Can I get it from curl instance ? or is there any tool like fiddler for Mac (I am working Mac OS ) ?
有什么方法可以查看 curl 请求标头。我可以从 curl 实例中获取它吗？或者有没有像 fiddler for Mac 这样的工具（我正在使用 Mac OS）？
Yes, you can get the request headers with the following:
是的，您可以使用以下内容获取请求标头：
<?php
...
curl_setopt($ch, CURLINFO_HEADER_OUT, true); // enable tracking
$result = curl_exec($ch);
var_dump(curl_getinfo($ch, CURLINFO_HEADER_OUT)); // request headers
?>

In PHP 5.5.0 it looks like you can now get the cookies in one line but I only get back an empty array using this with PHP 7.1.0:
在 PHP 5.5.0 中，看起来您现在可以在一行中获取 cookie，但我只能在 PHP 7.1.0 中使用它返回一个空数组：
CURLINFO_COOKIELIST - get all known cookies
CURLINFO_COOKIELIST - 获取所有已知的 cookie
$cookies = curl_getinfo($curl, CURLINFO_COOKIELIST);
