.htaccess中的动态环境变量

Question

我正在努力弄清楚如何根据我的场景使用SetEnvIf来使环境变量工作,并且想知道是否有人可以告诉我该怎么做,或者举个例子.

我的结果是我需要根据环境变量进行以下重定向,我还有其他需要使用此逻辑的情况.

我有下面的内容,所以重定向只发生在制作上

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{ENV:environment} production
    RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</IfModule>

我希望我可以设置以下内容,但无法弄明白.

SetEnvIf environment ^(.*)$ environment=production #set it to production, if it is not already set?
SetEnvIf Host ^staging. environment=staging
SetEnvIf Host .dev$ environment=wamp

理想情况下,我的psudo代码将是

SetEnvIf environment is not set, set to production
SetEnvElse host starts with staging, set to staging
SetEnvElse host ends with dev, set to wamp

然后在我的PHP中我得到了

<?php

if( getenv('environment') ){
    exit(getenv('environment'));
}
else {
    exit("environment not found");
}

我的输出肯定是

environment not found

任何人都能指出我做错的方向吗？

经过几个小时,我终于得到了一个工作解决方案,允许基于环境的动态.htaccess

对于任何对类似设置感兴趣的人,这里是我们的配置,它自动处理SSL,WWW重定向,Apache Auth和Is_Admin标志.
