使用PHP cURL扩展在两个网站之间共享相同的cookie(share the same cookie between two website using PHP cURL extension)

 我想在我的Gmail帐户中获取一些电子邮件的内容。 我想使用PHP cURL扩展来执行此操作。 我在第一次尝试时遵循了以下步骤： 
 
 
 
 在PHP代码中，输出https://www.google.com/accounts/ServiceLoginAuth的内容。 
 
 
 在浏览器中，用户输入用户名和密码进行登录。 
 
 
 在PHP代码中，将cookie保存在名为cookie.txt的文件中。 
 
 
 在PHP代码中，将请求发送到https://mail.google.com/以及从cookie.txt检索到的cookie并输出内容。 
 
 
 以下代码不起作用： 
 
$login_url = 'https://www.google.com/accounts/ServiceLoginAuth';
$gmail_url = 'https://mail.google.com/';
$cookie_file = dirname(__FILE__) . '/cookie.txt';

$ch = curl_init();

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
curl_setopt($ch, CURLOPT_URL, $login_url);
$output = curl_exec($ch);
echo $output;

curl_setopt($ch, CURLOPT_URL, $gmail_url);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
$output = curl_exec($ch);
echo $output;

curl_close($ch);

I want to get the contents of some emails in my gmail account. I would like to use the PHP cURL extension to do this. I followed these steps in my first try:
 
 
 
In the PHP code, output the contents of https://www.google.com/accounts/ServiceLoginAuth.
 
 
In the browser, the user input username and password to login.
 
 
In the PHP code, save cookies in a file named cookie.txt.
 
 
In the PHP code, send request to https://mail.google.com/ along with cookies retrieved from cookie.txt and output the contents.
 
 
The following code does not work:
 
$login_url = 'https://www.google.com/accounts/ServiceLoginAuth';
$gmail_url = 'https://mail.google.com/';
$cookie_file = dirname(__FILE__) . '/cookie.txt';

$ch = curl_init();

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
curl_setopt($ch, CURLOPT_URL, $login_url);
$output = curl_exec($ch);
echo $output;

curl_setopt($ch, CURLOPT_URL, $gmail_url);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
$output = curl_exec($ch);
echo $output;

curl_close($ch);
