您重定向到 $ 1 在这两种情况下，你没有RewriteBase指令，告诉阿帕奇哪里根这样的相对路径。

You are redirecting to $1 in both cases, and you don't have a RewriteBase directive to tell Apache where to root such a relative path.

先试的$ 1把一根斜线把它固定到Web服务器的根目录下，例如：

Try adding a root slash before the $1 to anchor it to the root of your webserver, for instance:

RewriteRule ^(.*)$ /$1.php [L]
