阿帕奇重写规则，太多的重定向错误

Question

我想实现我需要别人的帮助下COMPLE重写规则..

这里是我的要求..

HTTPS://{domain}/contextPath/browse  //should transformed to 
HTTPS://{domain}/contextPath?dl=browse 

另一个样品..

HTTPS://{domain}/contextPath/login  //should transformed to 
HTTPS://{domain}/contextPath?dl=login 

当我试图用这个规则，我收到了太多错误重定向..

RewriteRule ^/contextPath/(*) ^/contextPath?dl=$1 [R,L] 

能否请你帮我这个

RewriteRule ^/contextPath/(*) ^/contextPath?dl=$1 [R,L]

似乎有一些问题与此指令：

• 模式(*)是无效，应该是(.*)
• ^字符在替换开始时没有意义。 ^（插入符号）是正则表达式中字符串锚的开始。替换字符串不是一个正则表达式。因此，除非您的网址中有文字^，否则应该省略。
• 这应该是内部重写，而不是外部重定向（R标志）。想必您不想将您的/contextPath?dl=网址暴露给用户？

尝试像在你的Apache配置如下：

# Internally rewrite the request providing the "dl" param is not already present 
RewriteCond %{QUERY_STRING} !dl= 
RewriteRule ^/contextPath/(.+) contextPath?dl=$1 [L]
