好的，我已经破解了它，通过欺骗$\\u服务器变量并预定义一些常量，我能够阻止Wordpress在包含wp load后重定向。php。

define(\'WP_USE_THEMES\', false);
define( \'DOMAIN_CURRENT_SITE\', $siteRow[\'domain\'] );
define( \'PATH_CURRENT_SITE\', \'/\' );
define( \'SITE_ID_CURRENT_SITE\', 1 );
define( \'BLOG_ID_CURRENT_SITE\', $siteRow[\'wp_blog_id\'] );

$_SERVER = array(
    "HTTP_HOST" => $siteRow[\'domain\'],
    "SERVER_NAME" => $siteRow[\'domain\'],
    "REQUEST_URI" => "/",
    "REQUEST_METHOD" => "GET"
);

require_once WP_PATH.\'wp-load.php\';
switch_to_blog($siteRow[\'wp_blog_id\']);
