匹配第二个规则的网址也将匹配的第一个规则。作为第一个规则被标记为L时，第二条规则将永远不会被施加

URLs that match the second rule will also match the first rule. As the first rule is marked "L", the second rule will never be applied.

也许你应该匹配绝对URL - 以正则表达式^ / 来匹配URL的开头，并以 $ 系铃人code>到URL的末尾匹配。请记住，重写规则应用于URL路径（所有在它后面website.com，包括斜线）。

Maybe you should match absolute URLs - begin the regex with ^/ to match the beginning of a URL, and end it with $ to match the end of the URL. Remember that rewrite rules are applied to the URL path (everything that follows website.com, including the slash).

例如（没有测试这门课程的）：

For example (didn't test this of course):

# Example: website.com/books.php -> website.com/index.php?com=cat&catname=books
RewriteRule ^/([^/]+).php$ /index.php?com=cat&catname=$1 [L]
# Example: website.com/books/java.php -> website.com/index.php?com=detail&catname=books&prodname=java
RewriteRule ^/([^/]+)/([^/]+).php$ /index.php?com=detail&catname=$1prodname=$2 [L]
