每次调用管理页面都会加载\\wp-admin\\admin.php 文件

例如，从\\wp-admin\\index.php 文件：

/** Load WordPress Bootstrap */
require_once( dirname( __FILE__ ) . \'/admin.php\' );

从…起\\wp-admin\\admin.php:

require_once(ABSPATH . \'wp-admin/includes/admin.php\');

auth_redirect();

// Schedule trash collection
if ( !wp_next_scheduled(\'wp_scheduled_delete\') && !defined(\'WP_INSTALLING\') )
    wp_schedule_event(time(), \'daily\', \'wp_scheduled_delete\');

set_screen_options();

/**
 * Checks if a user is logged in, if not it redirects them to the login page.
 *
 * @since 1.5
 */
function auth_redirect() {

    [...]

    $login_url = wp_login_url($redirect, true);

    wp_redirect($login_url);
    exit();
