将 RewriteRule 与 [L] 标志匹配后，重写不会停止

Question

我想将路径/health重写为/health.php。

我目前有以下 .htaccess 文件，带有 catch-all 规则：

RewriteEngine On
RewriteRule ^.*$ index.php [L]

所以我只是在包罗万象之前添加了一条新规则：

RewriteEngine On
RewriteRule ^health$ health.php [L]
RewriteRule ^.*$ index.php [L]

但令我惊讶的是，当我在浏览器中请求 /health 时，它并没有重写为 health.php。

但是，当我删除最后一个（包罗万象）规则时，它按预期工作。

为什么 mod_rewrite 在匹配带有[L] 标志的规则后不停止处理规则？

Answer 1

找到了。我一直认为[L] 标志停止了所有规则的处理，期间。实际上，它只是停止处理当前规则集中的规则，然后根据重写的请求重新运行整个规则集。

因此，我的包罗万象的代码终于捕捉到了它，正如rewrite log 所示：

strip per-dir prefix: [...]/public/health -> health
applying pattern '^health$' to uri 'health'
rewrite 'health' -> 'health.php'
add per-dir prefix: health.php -> [...]/public/health.php
strip document_root prefix: [...]/public/health.php -> /health.php
internal redirect with /health.php [INTERNAL REDIRECT]

strip per-dir prefix: [...]/public/health.php -> health.php
applying pattern '^health$' to uri 'health.php'
strip per-dir prefix: [...]/public/health.php -> health.php
applying pattern '^.*$' to uri 'health.php'
rewrite 'health.php' -> 'index.php'
add per-dir prefix: index.php -> [...]/public/index.php
strip document_root prefix: [...]/public/index.php -> /index.php
internal redirect with /index.php [INTERNAL REDIRECT]

strip per-dir prefix: [...]/public/index.php -> index.php
applying pattern '^health$' to uri 'index.php'
strip per-dir prefix: [...]/public/index.php -> index.php
applying pattern '^.*$' to uri 'index.php'
rewrite 'index.php' -> 'index.php'
add per-dir prefix: index.php -> [...]/public/index.php
initial URL equal rewritten URL: [...]/public/index.php [IGNORING REWRITE]

在this blog 上找到的解决方案涉及在 catch-all 规则之前放置一个条件，以便仅在之前没有处理过内部重定向时执行它：

RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^.*$ index.php [L]
