解析JSON返回无

Question

我使用此代码在购物车中订购产品。我正在尝试获取生成订单的订单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。代码运行时，它总是打印零？

Moltin.sharedInstance().cart.order(withParameters: orderParameters, success: { (responceDictionary) -> Void in 
    print(responceDictionary) 

    let orderID1 = responceDictionary!["result.id"] as? String 
    let orderID = orderID1 

    print(orderID) 

我试图分析这些数据：

你不可错过的关键路径的关键订阅和id是一个int：

if let resultDictionary = responceDictionary["result"] as? [String:Any], 
    let orderID = resultDictionary["id"] as? Int { 
     let orderIDString = "\(orderID)" 
     print(orderIDString) 
}
