问题描述
我正在使用此代码在购物车中订购产品.我正在尝试获取所生成订单的订单ID.我不太确定发生了什么，因为结果"是AnyHashable值，ID是我需要的值.运行代码时，它始终显示nil吗?
I'm using this code to order a product place in the cart. I'm trying to get the order ID of the order generated. I'm not too sure what is happening as the 'result' is the AnyHashable value and ID is the value I need. When the code is ran, it always prints nil?
Moltin.sharedInstance().cart.order(withParameters: orderParameters, success: { (responceDictionary) -> Void in
print(responceDictionary)
let orderID1 = responceDictionary!["result.id"] as? String
let orderID = orderID1
print(orderID)

推荐答案
您不能将密钥路径传递给密钥订阅，并且id是Int:
You cannot pass a key path to a key subscription and id is an Int:
if let resultDictionary = responceDictionary["result"] as? [String:Any],
let orderID = resultDictionary["id"] as? Int {
let orderIDString = "\(orderID)"
print(orderIDString)
}
