Htaccess - 将下划线结合到连字符和大写到小写 301 重定向

Question

目前我在我的网站上使用下划线连字符 301，这运行良好，但我还想将所有链接转换为小写，并将大写添加到小写重写。

我可以这样做，但使用当前方法它会执行以下操作，我认为这对 SEO 不是很好：

1. 原始网址
2. 301
3. 已替换连字符
4. 301
5. 连字符小写 URL

如何将以下重写合并到一个查询中，以便通过 301 将带有下划线或大写的 url 转换为连字符和小写？

下划线改写连字符

RewriteRule ^post/([^_]*)_([^_]*_.*)$ /posts/new-category-1/$1-$2 [L,NE]
RewriteRule ^post/([^_]*)_([^_]*)$ /posts/new-category-1/$1-$2 [L,NE,R=301]

RewriteRule ^forum/([^_]*)_([^_]*_.*)$ /forums/new-category-1/$1-$2 [L,NE]
RewriteRule ^forum/([^_]*)_([^_]*)$ /forums/new-category-1/$1-$2 [L,NE,R=301]

大写到小写重写

httpd.conf

RewriteMap lc int:tolower

.htaccess

RewriteCond %{REQUEST_URI} ^[^A-Z]*[A-Z].*
RewriteRule ^ ${lc:%{REQUEST_URI}} [L,R=301]

Answer 1

您可以通过以下规则避免多个301：

RewriteRule ^(post|forum)/([^_]*)_([^_]*_.*)$ /$1/$2-$3 [L,NE]

# if there is any upper case letter then do both lowercase conversion AND
# underscore to hyphen replacement
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule ^(post|forum)/([^_]*)_([^_]*)$ /${lc:$1}/${lc:$2}-${lc:$3} [L,NE,R=301]

# otherwise regular underscore to hyphen replacement
RewriteRule ^(post|forum)/([^_]*)_([^_]*)$ /$1/$2-$3 [L,NE,R=301]

# and regular lower case conversion
RewriteRule ^(post|forum)/[^A-Z]*[A-Z] ${lc:%{REQUEST_URI}} [L,R=301]
