dump(request());会得到object(think\Request)#8 (38) {
["instance":protected] => NULL
["config":protected] => object(think\Config)#3 (2) {
["config":"think\Config":private] => array(10) {
["app"] => array(65) {
["app_name"] => string(0) ""
["app_host"] => string(0) ""
["app_debug"] => bool(true)
["app_trace"] => bool(true)
["app_status"] => string(0) ""
["app_multi_module"] => bool(false)
["auto_bind_module"] => bool(false)
["root_namespace"] => array(0) {
}
["default_return_type"] => string(4) "html"
["default_ajax_return"] => string(4) "json"
["default_jsonp_handler"] => string(11) "jsonpReturn"
["var_jsonp_handler"] => string(8) "callback"
["default_timezone"] => string(13) "Asia/Shanghai"
……
……怎么取得几级里面的值，例如dump(require()->config()-config()->app()->default_return_type); // html 最佳答案
