Question

我正在尝试实现以下mod_rewrite规则：

host.com/developer/ =＆gt; host.com/developer/index.py
host.com/developer/branchX =＆gt; host.com/developer/index.py?branch=branchX
host.com/developer/branchX/commitY =＆gt; host.com/developer/index.py?branch=branchX&commit=commitY

目前，相应的配置部分如下所示：

  Options FollowSymLinks
  AllowOverride None
  RewriteEngine on
  RewriteRule ^([^/]+)$                   /$1/index.py                          [L]
  RewriteRule ^([^/]+)/([^/]+)            /$1/index.py?branch=$2                [L]
  RewriteRule ^([^/]+)/([^/]+)/([^/]+)$   /$1/index.py?branch=$2&commit=$3      [L]

但是，在最初重写URL之后，会发生内部重定向，并且会再次重写URL，从而破坏它。该过程重复多次，最终导致500错误。日志（删除了时间戳和perdir部分）：

[..initial] (3) strip per-dir prefix: /home/www/host.com/master/a -> master/a
[..initial] (3) applying pattern '^([^/]+)$' to uri 'master/a'
[..initial] (3) strip per-dir prefix: /home/www/host.com/master/a -> master/a
[..initial] (3)  applying pattern '^([^/]+)/([^/]+)' to uri 'master/a'
[..initial] (2) rewrite 'master/a' -> '/master/index.py?branch=a'

[..initial/redir#1] (3) strip per-dir prefix: /home/www/host.com/master/index.py -> master/index.py

[..initial/redir#1] (3) split uri=/master/index.py?branch=index.py -> uri=/master/index.py, args=branch=index.py

如何修复规则以防止无休止的内部重定向？感谢。

问题是你要重写的网址在下一次传递中是匹配的。 L指定最后一条规则但仅针对规则的执行，在某些情况下（在本例中为内部重定向）会再次处理URL。解决方案是添加RewriteCond以防止循环，如下所示：

RewriteEngine on
RewriteCond %{REQUEST_URI}              !index\.py
RewriteRule ^([^/]+)$                   /$1/index.py                          [L]
RewriteCond %{REQUEST_URI}              !index\.py
RewriteRule ^([^/]+)/([^/]+)            /$1/index.py?branch=$2                [L]
RewriteCond %{REQUEST_URI}              !index\.py
RewriteRule ^([^/]+)/([^/]+)/([^/]+)$   /$1/index.py?branch=$2&commit=$3      [L]
