是否可以检查当前页面是否已使用SSL打开?例如，我希望我的登录页面(login.php)检查是否使用SSL(https://mywebserver.com/login.php)访问了该页面.如果没有，请将其重定向到页面的SSL版本.

推荐答案

您应该能够检查是否已设置$_SERVER['HTTPS']，例如:

You should be able to check that $_SERVER['HTTPS'] is set, e.g.:

if (empty($_SERVER['HTTPS'])) {
    header('Location: https://mywebserver.com/login.php');
    exit;
}
