.htaccess 将子域重写到目录并将子域保留在 url 中

2021-12-21 00:00:00 regex php .htaccess apache mod-rewrite

我需要使用 .htaccess 将子域重写为子目录，但将子域保留在 url 中，如下所示:

I need to rewrite a subdomain to a subdirectory using .htaccess but keep the subdomain in the url like this:

浏览器中访问的 url:sub1.domain.com

Visited url in browser: sub1.domain.com

提供的网址:sub.domain.com/sub1/

我尝试了以下

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

但这会导致无限循环.我知道通过 php 执行此操作会更容易，但是使用 .htaccess 是否有任何解决方案?

but this leads to an endless loop. I know that it would be easier to do this by php but is there any solution for this with using .htaccess?

推荐答案

您可以在文档根目录中使用此规则:

You can use this rule in document root:

RewriteCond %{HTTP_HOST} ^subdomain.domain.com$ [NC]
RewriteRule ^((?!sub1/).*)$ /sub1/$1 [L,NC]

说明:

  • NC:忽略大小写
  • L:最后一条规则
  • RewriteCond %{HTTP_HOST} 行确保规则只对 subdomain 执行
  • (?!sub1/) 是否定前瞻表达式，表示请求的意思不是以 /sub1/
    • 开头
  • RewriteRule ^((?!sub1/).*)$/sub1/$1 [L,NC] 将当前路径重写为 /sub1/
  • NC: Ignore case
  • L: Last rule
  • RewriteCond %{HTTP_HOST} line makes sure that rule only executes for subdomain
  • (?!sub1/) is negative lookahead expression that means of request is not starting with /sub1/
  • RewriteRule ^((?!sub1/).*)$ /sub1/$1 [L,NC] rewrites current path to /sub1/<uri>
