在.htaccess文件elseif的条件块 - 我怎么会写一个if - elseif的？ [英] How would I write an if - elseif - elseif conditional block in an .htaccess file?

问题描述

这就是我要完成的伪code：

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

不过，这是我居然有这么远，这似乎并没有工作，我期望：

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

我AP preciate任何帮助，我可以提前得到。

I appreciate any help I can get in advance.

推荐答案

不是一个每本身答案（一开始是注释），但可能你有点帮助：

Not an answer per-se (started out as a comment), but may help you a bit:

您的方法不起作用，因为的RewriteBase不受的RewriteCond指令。一个的RewriteCond只能跟着另一个的RewriteCond或重写规则。的RewriteBase是一个完全不同的野兽：我不认为有条件的RewriteBase是可能的;我有模糊的感觉，它在启动时进行处理，所以不能动态地改变（但我可能是非常错误的这个）。谷歌有许多命中为有条件的RewriteBase，你可以看通过这些，但他们似乎主要是负面的。

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.

与 IfDefine 的玩弄以达到类似的效果将是值得一试。

Toying with IfDefine to achieve a similar effect would be worth a shot.

另外，你可以尝试使用规则集和环境变量这样做：

Alternatively, you could try doing it with RewriteRules and environmental variables:

 RewriteBase /

 RewriteCond %{HTTP_HOST} =stagingsite.com
 RewriteRule ^ - [E=FRB:/staging/mysite]

 RewriteCond %{HTTP_HOST} =localhost
 RewriteRule ^ - [E=FRB:/dev/mysite]

然后prePEND每个重写路径与FRB环境变量，如

And then prepend each rewrite path with the FRB environmental variable, like

 RewriteRule ^home$ %{ENV:FRB}/index.php

但是，这仅仅是一个未经测试的理论。

But this is just an untested theory.
