重寫規則301重定向的URL與多個查詢字符串

Question

我有這樣的URL：

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

我想打一個301重定向到

siteurl.com/category/6/internet/ 

我嘗試沒有成功：

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

有關更多信息：Duplicated content on google. htaccess or robots.txt?

有什麼幫助嗎？

Xtra Edit;該頁面也可以通過siteurl.com/category.php?id=6（witohut名稱查詢）訪問。什麼是處理這個問題的最好方法？將這種類型的URL重定向到主頁？如果是這樣，我該怎麼做？

查詢字符串不會出現在RewriteRule表達式中。相反，您必須通過%{QUERY_STRING}與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?時，只需要避免在URL的末尾reapeating查詢。

# 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]
