将大写 url 重写为小写 url htaccess

Question

我希望将包含大写字符的网址重定向到小写网址。不幸的是，我无权访问 httpd.config 文件。所以我尝试了这种方法来用 htaccess 文件重写 url：http://www.askapache.com/htaccess/rewrite-uppercase-lowercase.html。但是它添加了额外的 / 因为它是一个循环，并且当 url 包含两个以上的部分（例如 www.mysite.com/part1/part2/part3/ ）时它也不起作用（504 错误）

我该如何解决这个问题，或者有其他/更好的方法吗？

如果您查看您的 Apache 错误日志（这很可能是由于这件事造成的），您应该会看到以下内容：

一切顺利，直到应用路径信息后缀。我不确定为什么，但我知道将DPI 标志应用于将大写转换为小写的 26 个 RewriteRules 很可能会解决您的问题。

# 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$2 [DPI]
RewriteRule ^([^B]*)B(.*)$ $1b$2 [DPI]
RewriteRule ^([^C]*)C(.*)$ $1c$2 [DPI]
RewriteRule ^([^D]*)D(.*)$ $1d$2 [DPI]
RewriteRule ^([^E]*)E(.*)$ $1e$2 [DPI]
RewriteRule ^([^F]*)F(.*)$ $1f$2 [DPI]
RewriteRule ^([^G]*)G(.*)$ $1g$2 [DPI]
RewriteRule ^([^H]*)H(.*)$ $1h$2 [DPI]
RewriteRule ^([^I]*)I(.*)$ $1i$2 [DPI]

RewriteRule ^([^Y]*)Y(.*)$ $1y$2 [DPI]
RewriteRule ^([^Z]*)Z(.*)$ $1z$2 [DPI]

# If there are any uppercase letters, restart at very first RewriteRule in file.
RewriteRule [A-Z] - [N]

RewriteCond %{ENV:HASCAPS} TRUE
RewriteRule ^/?(.*) /$1 [R,L]

在 VirtualHosts 站点目录（已启用站点）

RewriteEngine On
RewriteMap lowercase int:tolower 

在 .htaccess:

RewriteCond $1 [A-Z]
RewriteRule ^(.*)$ /${lowercase:$1} [R=301,L]
