我需要一个大约 2012 年的示例，说明如何使用 PHP cURL 登录 UPS。我不会在通话之间关闭会话。需要获取 3 个页面，1) 登录页面 2) 密码页面和 3) 发票页面
我以前有它的工作，但它不再。我删除了 cookie 文件，它工作了一段时间，然后我收到消息“由于不活动，您当前的请求已超时。您需要重新启动请求。” 如果我不在窗口内登录，即使成功登录也会超时。我尝试删除cookie文件并重新开始，但没有奏效。任何想法如何使它超时窗口是无限的？这是我的代码，已删除凭据：
$cookie_file_path = "/tmp/cookie.txt";
// remove previous cookie
if (file_exists($cookie_file_path)) {
`rm -fr {$cookie_file_path}`;
}
$login_url = 'https://www.ups.com/one-to-one/login';
$password_url = 'https://www.ups.com/one-to-one/password';
$invoice_url = 'upsDOTcomSLASHviewbillSLASHinvoices';

即使在删除并重新创建 cookie 文件后，我也无法通过第一个登录页面，因为我得到了：
由于不活动，您当前的请求已超时。您将需要重新开始您的请求。
