你可以钩住parse_request 并欺骗WordPress，使其认为它与一个页面永久链接相匹配，如果存在一个类别术语具有相同的slug：

/**
 * Override query for pages that match a category slug.
 * 
 * @param   WP  $wp
 */ 
function wpse_177014_category_to_page ( $wp ) {
    if ( ! empty( $wp->query_vars[\'category_name\'] ) && get_page_by_path( $slug = $wp->query_vars[\'category_name\'] ) ) {
        if ( ! empty( $wp->query_vars[\'paged\'] ) )
            $page = $wp->query_vars[\'paged\'];
        else
            $page = \'\';

        $wp->matched_query = "pagename=$slug&page=$page";
        $wp->query_vars    = array(
            \'pagename\' => $slug,
            \'page\'     => $page,    
        );      
    }
}

add_action( \'parse_request\', \'wpse_177014_category_to_page\' );
