json - 当变量在 Swift 中作为 AnyObject 传入时，字典键和值丢失引号 ("")

Question

我正在 Swift 中创建一个 [String: AnyObject] 类型的字典，其中包含键:值对以及嵌套字典。每个项目都被转换为 AnyObject。但是，只有外部字典的键:值对在字符串两边带有引号(“”)。嵌套字典的键:值对一起丢失。我将整个嵌套字典转换为 AnyObject 元素。

let parameter: [String: AnyObject] = [
                   "cartonNumber": "\(cartonNumber)" as AnyObject,
                   "status": "DELIVERED" as AnyObject,
                   "documentNumbers":
                       [
                         "\"shipmentNumber\"": "\(currentShipmentNumber)",
                        "referenceNumber": "\(referenceNumber)",
                        "proNumber": "\(proNumber)",
                        "billOfLadingNumber": "\(bolNumber)",
                        "trackingNumber": "\(trackingNumber)"
                       ] as AnyObject,
                           "sourceLocation": [
                                "plantCode":"1028"
                           ] as AnyObject,
            "targetLocation": [
                           "id":"73e64de9-36cd-4b20-be1d-13003e455008",
                           "type":"store/stores"
                       ] as AnyObject,
            "shipDate": "\(dateToday)" as AnyObject,
            "items": [
            "\"product\"": [
                "gtin":"00004007334274"
                ],
            "quantity": 2,
            "documentNumbers":
                [
          "deliveryNumber": "\(deliveryNumber)"
            ],
               ] as AnyObject
        ]

希望在嵌套字典中的键:值周围保留引号

如果我在调试器中打印你的 JSON，我会得到这个输出。看来所有的“”都是正确的。您能解释一下您到底在尝试什么吗？
