首先谢谢你，我开始通过使用你的代码编程来实现 creditmemo，我遇到的问题是创建了 credit memom 但没有产品。我将分享我的代码，以便您使用它。
/*
I think your problem is with the content of the variable data, I'll give you an example:
array(6) {
["items"] => array(2) {
[11] => array(1) {
["qty"] => string(6) "2"
}
[13] => array(1) {
["qty"] => string(1) "0"
}
}
["do_offline"] => string(1) "1"
["comment_text"] => string(0) ""
["shipping_amount"] => string(1) "0"
["adjustment_positive"] => string(1) "0"
["adjustment_negative"] => string(1) "0"
["qtys"] => array(2) {
[11] => int(2)
[13] => int(0)
}
}
*/
