获取完整的URL在PHP重定向到SSL [英] Get full URL in PHP to redirect to SSL

问题描述

我有我需要强制SSL一些PHP页面。我不想与mod_rewrite的或类似的东西做到这一点，我想保持所有的逻辑在PHP。现在我有code，看起来像这样：

I have some PHP pages that I need to force SSL for. I don't want to do it with mod_rewrite or anything like that, I want to keep all the logic in PHP. Right now I have code that looks like this:

if($_SERVER["HTTPS"] != "on") {
    header("HTTP/1.1 301 Moved Permanently");
    header("Location: https://" . $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"]);
    exit();
}

由于服务器名称是通用的，因为我托管多个站点，不同的域名，然而，这并不正常工作。所以SERVER_NAME是WWW。以上code会重定向到的https：//www/index.php 这是无效的。

This does not work however because the server name is generic as I am hosting multiple sites with different domain names. So the SERVER_NAME is "www". The above code will redirect to https://www/index.php which is not valid.

我已经试过的print_r（$ _ SERVER）来查看可用的变量我，但他们都不给我完整的URI请求（http://example.com/index.php），以及下一个最接近的选项，我可以看到而不是SERVER_NAME是SERVER_ADDR这也不会帮我，因为要去 https://127.0.0.1/index.php 必去的默认的Apache网站并没有给定义example.com（更不用提我的SSL证书将不再有效）。

I have tried print_r($_SERVER) to see the variables available to me but none of them give me the full URI request (http://example.com/index.php), and the next closest option I can see instead of SERVER_NAME is SERVER_ADDR which will also not help me, because going to https://127.0.0.1/index.php will go to the default apache site and not to the definition for "example.com" (not to mention that my SSL cert would no longer be valid).

有什么建议？

推荐答案

在最后我不得不谁管理Apache的代理服务器来添加家伙代理preserveHost在到apache2.conf，这使HTTP_HOST（和SERVER_NAME）的正确转发到后端的Apache服务器。

In the end I had the guy who manages the Apache proxy server to add ProxyPreserveHost On to apache2.conf and this enabled forwarding of HTTP_HOST (and SERVER_NAME) properly to the backend Apache server.

感谢大家对你的建议，我很抱歉，这个问题最终被一些愚蠢的事，这不是即使在我的问题的范围。如果我工作的Apache服务器没有在它前面的代理，你的大部分建议都已经被证明完全正确的。

Thank you everyone for your suggestions, I'm sorry the problem ended up being something stupid that wasn't even in the scope of my question. If the Apache server I was working on did not have a proxy in front of it, most of your suggestions would have proven completely accurate.
