使用 PHP 从 HTTP 重定向到 HTTPS

Redirecting from HTTP to HTTPS with PHP(使用 PHP 从 HTTP 重定向到 HTTPS)

问题描述

我在一个购物车网站上工作，我想在用户输入账单详细信息时将用户重定向到 HTTPS 页面，并在他退出之前保持下一页的 HTTPS 连接.

I'm working on a shopping cart website and I would like to redirect the user to a HTTPS page when he's entering his billing details and maintain the HTTPS connection for the next pages until he logs out.

我需要在服务器上安装什么(我使用的是 Apache)才能执行此操作，以及如何从 PHP 完成此重定向?

What do I need to install on the server (I'm using Apache) in order to do this, and how can this redirect be done from PHP?

推荐答案

尝试这样的事情(应该适用于 Apache 和 IIS):

Try something like this (should work for Apache and IIS):

if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === "off") {
    $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $location);
    exit;
}
