Question

我有这个JSON，响应中有多个具有相同键值名称的字段，我该如何访问它们呢？我正在快速使用Codable，可以从“ pricingInfo”访问第一个“ value”，但是如何访问其他priceingInfo？

"fareComponentList":[

            },
            "value":0
         }
      }
   }
]

我想做的是，存储每个

中的“值”

"pricingInfo":{  
   "baseFare":{  
      "amount":{  
         "currency":{  
            "code":"USD"
         },
         "value":45
      };

我该怎么办？（基本上是在尝试获取成人，儿童和婴儿的价格）

对于您的JSON，这可以是您的可编码模型。

typealias FareComponentList = [FareComponentListElement]

struct FareComponentListElement: Codable {
    let passengerFareInfoList: [PassengerFareInfoList]
    let pricingOverview: PricingOverview
}

struct PassengerFareInfoList: Codable {
    let passengerTypeQuantity: PassengerTypeQuantity
    let pricingInfo: PricingInfo
    let fareInfoList: [FareInfoList]
}

struct FareInfoList: Codable {
    let cabinClassCode, fareReferenceCode: String
    let flightSegmentSequence: Int

使用以上模型，可以访问以下值。

let passengerType = fareComponentList[0].passengerFareInfoList[0].passengerTypeQuantity.passengerType // ADLT / CHLD / INFT
let amount = fareComponentList[0].passengerFareInfoList[0].pricingInfo.baseFare.amount.value

如果字典中有多个json字段具有相同的名称，如何获取值？
