如何写一个htaccess文件夹通配符子域 [英] How to write a htaccess file to wildcard folder to subdomain

问题描述

我想我所有的文件夹（使用通配符）重定向到其子域。例如：

  

www.mywebsite.com/folder1到folder1.mywebsite.com/~~V
  www.mywebsite.com/folder2到folder2.mywebsite.com/~~V
  www.mywebsite.com/folder3到folder3.mywebsite.com /

现在无需编写规则他们每个人，有没有办法把它们全部重定向到各自的子域名？

我想：

  RewriteEngine叙述上
的RewriteCond％{HTTP_HOST}！^ WWW \ .mywebsite \ .COM $
的RewriteCond％{HTTP_HOST} ^（\ W +）\。mywebsite \ .COM $
重写规则^（。*）$ / 1％/ $ 1 [QSA]
 

但它给了我一个内部错误500

解决方案

您需要保持规则的循环，使用条件，首先检查 /％1 / $ 1 确实存在，或的URI尚未与％1

所以：

  RewriteEngine叙述上
的RewriteCond％{HTTP_HOST}！^ WWW \ .mywebsite \ .COM $
的RewriteCond％{HTTP_HOST} ^（\ W +）\。mywebsite \ .COM $
的RewriteCond％{DOCUMENT_ROOT} /％1％{REQUEST_URI} -f [OR]
的RewriteCond％{DOCUMENT_ROOT} /％1％{REQUEST_URI} -d
重写规则^（。*）$ / 1％/ $ 1 [QSA]
 

或者

  RewriteEngine叙述上
的RewriteCond％{HTTP_HOST}！^ WWW \ .mywebsite \ .COM $
的RewriteCond％{HTTP_HOST} ^（\ W +）\。mywebsite \ .COM $
的RewriteCond％{REQUEST_URI}：％1 ^ /（[^ /] +）/（[^：] *）：！\ 1
重写规则^（。*）$ / 1％/ $ 1 [QSA]
 

在 ^ /（[^ /] +）/（[^：] *）：！\ 1 EX pression团体第一次在URI文件夹，并与反向引用它\ 1 。如果这些都是平等的，那么在URI的第一个文件夹是％1 这是backreferenced到previous比赛（\ w +）。

I'm trying to redirect all my folders (using a wildcard) to their subdomain. For example:

www.mywebsite.com/folder1 to folder1.mywebsite.com/
www.mywebsite.com/folder2 to folder2.mywebsite.com/
www.mywebsite.com/folder3 to folder3.mywebsite.com/

Now without writing a rule for each one of them, is there a way to redirect them all to their respective subdomain?

I tried:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.mywebsite\.com$
RewriteCond %{HTTP_HOST} ^(\w+)\.mywebsite\.com$
RewriteRule ^(.*)$ /%1/$1 [QSA]

But it gives me an internal error 500

解决方案

You need to keep the rules from looping, use a condition to first check if the /%1/$1 actually exists, or that the URI doesn't already start with %1

So:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.mywebsite\.com$
RewriteCond %{HTTP_HOST} ^(\w+)\.mywebsite\.com$
RewriteCond %{DOCUMENT_ROOT}/%1%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}/%1%{REQUEST_URI} -d
RewriteRule ^(.*)$ /%1/$1 [QSA]

Or:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.mywebsite\.com$
RewriteCond %{HTTP_HOST} ^(\w+)\.mywebsite\.com$
RewriteCond %{REQUEST_URI}:%1 !^/([^/]+)/([^:]*):\1
RewriteRule ^(.*)$ /%1/$1 [QSA]

The !^/([^/]+)/([^:]*):\1 expression groups the first folder in the URI, and backreferences it with \1. If those are equal, then the first folder in the URI is %1 which is backreferenced to the previous match (\w+).
