重写规则301重定向的URL与多个查询字符串

Question

我有这样的URL：

siteurl.com/category.php?id=6&name=internet 

我想打一个301重定向到

siteurl.com/category/6/internet/ 

我尝试没有成功：

RewriteRule ^category.php?id=([^&]*)&name=([^&]*) /category/$1/$2/ [R=301,L] 

有关更多信息：Duplicated content on google. htaccess or robots.txt?

有什么帮助吗？

Xtra Edit;该页面也可以通过siteurl.com/category.php?id=6（witohut名称查询）访问。什么是处理这个问题的最好方法？将这种类型的URL重定向到主页？如果是这样，我该怎么做？

查询字符串不会出现在RewriteRule表达式中。相反，您必须通过%{QUERY_STRING}与RewriteCond匹配。

RewriteEngine On 
# Capture the id and name into %1 and %2 from the query string 
RewriteCond %{QUERY_STRING} ^id=(\d+)&name=([a-zA-Z-]+) 
# If the query string does not include noredirect= 
# This protects against a rewrite loop when attempting to 301 redirect the ugly URL 
RewriteCond %{QUERY_STRING} !noredirect= 
# Rewrite category.php to /category/id/name 
RewriteRule ^category\.php /category/%1/%2/? [L,R=301] 

的?时，只需要避免在URL的末尾reapeating查询。

# I assume you also have the following rule, which configures the pretty URL in the first place 
# Then in the rule which points the pretty URL to the real internal one, add 
# the fake query string param noredirect=1, which won't actually be used by PHP. It just 
# matches in the rules above to prevent rewriting when present 
RewriteRule ^category/(\d+)/([^/]+) category.php?id=$1&name=$2&noredirect=1 [L]
