- if ( strpos( $user_agent, 'Googlebot' ) === false && strpos( $user_agent, 'Bingbot' ) === false && strpos( $user_agent, 'Slurp' ) === false && strpos( $user_agent, 'DuckDuckBot' ) === false ) {
- global $wp_query;
- $wp_query->set_404();
- status_header( 404 );
- get_template_part( 404 );
- exit();
- }
- }
- }
- add_action( 'template_redirect', 'block_homepage_for_pc' );
二、nginx 屏蔽网站首页访问 允许蜘蛛访问的方法

- }
- # other rules
- }
三、NGINX 禁止PC访问 不影响蜘蛛抓取的方法
- if ($http_user_agent !~* (android|iphone|ipod|ipad|windows\s*phone|blackberry|symbian|bot|crawl|spider)) {
