.htaccess 如何检查 URI +在 RewriteRule 之前文件扩展名不存在

Question

当通过这样的 URL 访问页面时：

/pagename

如何通过 htaccess

/pagename.htm

检查以下文件是否存在，如果不存在则加载 index.php？

这就是我正在处理的内容：

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

我尝试过这种方法的变体，但没有运气： RewriteCond %{REQUEST_URI} !/.htm -f

Answer 1

# If the URI is not .htm and doesn't have any additonal params, try .htm
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(?![^/]+\.htm)([^/]+)$ $1.htm [L,R=302]
# Adding the R flag causes the URI to be rewritten in the browser rather than just internally

# If the URI is .htm but it doesn't exist, pass to index.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/\.]+\.htm)$ $1/no [L]

# Passes requested path as 'q' to index.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/no/?$ index.php?q=$1 [L]

应该对你来说相当优雅。如果找不到该文件，它只会将其传递给index.php。您当然可以修改它使用的变量，我只是将“q”用于通用目的。

另外，请注意，您可以将其压缩为一组 RewriteCond。我在这里出于注释目的对它们进行了扩展。
