我有N WordPress多站点中的站点数。我想限制个人网站登录，即：。，

• http://www.example.com/site1/wp-admin
• http://www.example.com/site2/wp-adminhttp://www.example.com/wp-admin. 如果可能，所有其他登录URL应重定向到各自的主页。是否有任何功能或.htaccess 实现这一目标的规则？

  .htaccess 文件：

  # BEGIN WordPress
  <IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteRule ^index\\.php$ - [L]
  
  # add a trailing slash to /wp-admin
  RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
  
  RewriteCond %{REQUEST_FILENAME} -f [OR]
  RewriteCond %{REQUEST_FILENAME} -d
  RewriteRule ^ - [L]
  RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
  RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\\.php)$ $2 [L]
  RewriteRule . index.php [L]
  </IfModule>
  # END WordPress
