将通配符子域重定向到子目录，而无需更改地址栏中的 URL [英] Redirect wildcard subdomains to subdirectory, without changing URL in address bar

问题描述

我在这里阅读了很多关于此的问题和答案，但似乎没有一个能解决我的具体问题.

I've read a lot of questions and answers about this on here but none that seem to solve my specific problem.

我想将任何子域重定向到要匹配的子目录.

I want to redirect any subdomain to the subdirectory to match.

所以:x.domain.com 会转到 domain.com/x，而 y.domain.com 会转到 domain.com/y - 但我想在地址栏中不更改 URL 的情况下执行此操作.

So: x.domain.com would go to domain.com/x, and y.domain.com would go to domain.com/y - But I want to do this without the URL in the address bar changing.

这是我目前所拥有的:

    Options +FollowSymLinks 

    RewriteEngine on

    RewriteBase /

    RewriteCond %{HTTP_HOST} !^(www)\. [NC]

    RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com [NC]

    RewriteRule ^ /%1 [P,L]

但这将我带到一个网站重定向循环，在子域仍然存在的 URL 栏中有一个不正确的地址.

But this takes me to a website redirect loop, with an incorrect address in the URL bar where the subdomain still exists.

例如，x.domain.com 将我带到 x.domain.com/x 并且我收到重定向循环错误.

For example, x.domain.com takes me to x.domain.com/x and I get a redirect loop error.

如果有人能指出我正确的方向，我将不胜感激！我改变的一切似乎都不起作用......

I'd be grateful if anyone can point me in the right direction! Nothing I change seems to work...

推荐答案

首先确保 apache 配置中的 vhost 配置正确，并且 domain.com 的所有子域都在同一个主机配置中(通配符):

First of all, make sure that the vhost in the apache configuration is properly configured and all subdomains of domain.com are in the same host configuration (wildcard):

<VirtualHost *:80>
ServerName domain.com
ServerAlias *.domain.com
...

您可以使用以下 htaccess 配置进行重定向:

You can get the redirect working with the following htaccess configuration:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ http://domain.com/%1/$1 [L,NC,QSA]

现在，如果您打开 asd.domain.com，它应该将您重定向到 domain.com/asd.您仍然会遇到问题，即重定向在 URL 地址栏中可见.为了防止这种情况，在您的服务器上启用 mod_proxy(并加载子模块)并将L"标志与P"标志交换:

Now, if you open asd.domain.com it should redirect you to domain.com/asd. You will still have the problem, that the redirect is visible in the URL address bar. In order to prevent this, enable mod_proxy (and load the submodules) on your server and exchange the "L" flag with the "P" flag:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ http://domain.com/%1/$1 [P,NC,QSA]

如果这不起作用，在子域调用时查看 vhost 配置和 error.log 的内容会很有帮助！

If this doesn't work, viewing the vhost configuration and the content of error.log on subdomain calling will be helpful!
