我想将example.com/para1/para2转换为example.com/PARA1/PARA2。我正在使用共享主机，因此只能将htaccess用于重写。我发现下面的htaccess代码将上层转换成下层，我尝试通过替换所有下层到上层以及上层到下层来使用它，但不幸的是，id无效。
RewriteEngine On
RewriteBase /
# If there are caps, set HASCAPS to true and skip next rule
RewriteRule [A-Z] - [E=HASCAPS:TRUE,S=1]
# Skip this entire section if no uppercase letters in requested URL
RewriteRule ![A-Z] - [S=28]
# Replace single occurance of CAP with cap, then process next Rule.
RewriteRule ^([^A]*)A(.*)$ $1a$2
RewriteRule ^([^B]*)B(.*)$ $1b$2

将非常感谢您的友善回答。

将upper -> lower转换为lower -> upper很简单，因为您已经完成了第一个工作。您要做的就是应用逆逻辑
RewriteEngine On
RewriteBase /
# If there are lowers, set HASLOWERS to true and skip next rule
RewriteRule [a-z] - [E=HASLOWERS:TRUE,S=1]
# Skip this entire section if no lowercase letters in requested URL
RewriteRule ![a-z] - [S=28]
# Replace single occurance of lower with LOWER, then process next Rule.
RewriteRule ^([^a]*)a(.*)$ $1A$2
RewriteRule ^([^b]*)b(.*)$ $1B$2
RewriteRule ^([^c]*)c(.*)$ $1C$2
RewriteRule ^([^d]*)d(.*)$ $1D$2
RewriteRule ^([^e]*)e(.*)$ $1E$2
RewriteRule ^([^f]*)f(.*)$ $1F$2
RewriteRule ^([^g]*)g(.*)$ $1G$2
RewriteRule ^([^h]*)h(.*)$ $1H$2
RewriteRule ^([^i]*)i(.*)$ $1I$2
RewriteRule ^([^j]*)j(.*)$ $1J$2
RewriteRule ^([^k]*)k(.*)$ $1K$2
RewriteRule ^([^l]*)l(.*)$ $1L$2
RewriteRule ^([^m]*)m(.*)$ $1M$2
RewriteRule ^([^n]*)n(.*)$ $1N$2

RewriteRule ^([^y]*)y(.*)$ $1Y$2
RewriteRule ^([^z]*)z(.*)$ $1Z$2
# If there are any lowercase letters, restart at very first RewriteRule in file.
RewriteRule [a-z] - [N]
RewriteCond %{ENV:HASLOWERS} TRUE
RewriteRule ^/?(.*) /$1 [R=301,L]
