如何在 .htaccess 文件中编写 if - elseif - elseif 条件块？
这就是我想用伪代码完成的事情：
if server.host equals 'productionsite.com' then
RewriteBase /
else if server.host equals 'stagingsite.com' then
RewriteBase /staging/mysite
else if server.host equals 'localhost' or server.host equals '127.0.0.1' then
Rewrite /dev/mysite
然而，这是我迄今为止实际拥有的，但似乎并没有像我预期的那样工作：
RewriteCond %{HTTP_HOST} =productionsite.com
RewriteBase /
RewriteCond %{HTTP_HOST} =stagingsite.com
RewriteBase /staging/mysite
RewriteCond %{HTTP_HOST} =localhost
RewriteBase /dev/mysite
我感谢我可以提前获得的任何帮助。
This is what I want to accomplish in pseudocode:
if server.host equals 'productionsite.com' then
RewriteBase /
else if server.host equals 'stagingsite.com' then
RewriteBase /staging/mysite
else if server.host equals 'localhost' or server.host equals '127.0.0.1' then
Rewrite /dev/mysite
However, this is what I actually have so far which doesn't seem to work as I expect:
RewriteCond %{HTTP_HOST} =productionsite.com
RewriteBase /
RewriteCond %{HTTP_HOST} =stagingsite.com
RewriteBase /staging/mysite
RewriteCond %{HTTP_HOST} =localhost
RewriteBase /dev/mysite
I appreciate any help I can get in advance.

本身不是答案（作为评论开始），但可能对您有一点帮助：
您的方法不起作用，因为 RewriteBase 不受 RewriteCond 指令的影响。 RewriteCond 后面只能跟另一个 RewriteCond 或 RewriteRule。 RewriteBase 是一个完全不同的野兽：我不认为有条件的 RewriteBase 是可能的；我有一种模糊的感觉，它是在启动时处理的，所以不能动态更改（但我对此可能是非常错误的）。谷歌有很多关于“条件重写库”的点击，你可能会浏览这些，但它们似乎大多是负面的。
玩弄 IfDefine 来实现类似的效果值得一试。
或者，您可以尝试使用 RewriteRules 和环境变量来执行此操作：
然后在每个重写路径前添加 FRB 环境变量，例如
但这只是一个未经测试的理论。
Not an answer per-se (started out as a comment), but may help you a bit:
Your approach doesn't work because the RewriteBase isn't affected by RewriteCond directives. A RewriteCond can only be followed by another RewriteCond or a RewriteRule. RewriteBase is an entirely different beast: I don't think that a conditional RewriteBase is possible; I have the vague feeling that it's processed at startup, so can't be changed dynamically (but I may be very wrong about this). Google has a number of hits for "conditional rewritebase", you may look through those, but they seem largely negative.
Toying with IfDefine to achieve a similar effect would be worth a shot.
Alternatively, you could try doing it with RewriteRules and environmental variables:
And then prepend each rewrite path with the FRB environmental variable, like
But this is just an untested theory.
