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。运行代码后，它始终显示nil吗？
Moltin.sharedInstance().cart.order(withParameters: orderParameters, success: { (responceDictionary) -> Void in
print(responceDictionary)
let orderID1 = responceDictionary!["result.id"] as? String
let orderID = orderID1
print(orderID)

最佳答案
您不能将密钥路径传递给密钥订阅，并且id是一个整数：
if let resultDictionary = responceDictionary["result"] as? [String:Any],
let orderID = resultDictionary["id"] as? Int {
let orderIDString = "\(orderID)"
print(orderIDString)
}
