ios - 如何解码包含日期信息的 JSON？

Question

我的 JSON 结构为:

"symbol": "SNAP",

"stock_exchange_short": "NYSE",
"timezone_name": "America/New_York",
"intraday": {

    "2019-12-20 15:59:00": {
        "open": "15.55",
        "close": "15.55",
        "high": "15.55",
        "low": "15.52",
        "volume": "670218"
    },
    "2019-12-20 15:58:00": {
        "open": "15.55",
        "close": "15.55",
        "high": "15.55",
        "low": "15.54",
        "volume": "284225"
    },
   ...
}

关于如何实现日期信息的任何想法我尝试像这样解析它:

public struct WorldTradingIntradayData: Decodable {
    let symbol : String
    let stock_exchange_short : String
    let timezone_name : String
    let intraday : Intraday?
 }
public struct Intraday: Decodable {
    let dateTime: WorldTradingIntradayDetails

 public struct WorldTradingIntradayDetails: Decodable {
     let open : String
     let close : String
     let high : String
     let low : String
     let volume : String
    }

但它没有按预期工作。知道如何做到这一点吗？

我认为它应该被视为字符串，那么如果你想将其转换为日期，你需要更改空格的T来创建dateFormatter:

struct WorldTradingIntradayData: Decodable {
    let symbol: String
    let stockExchangeShort: String
    let timezoneName: String
    let intraday: [String: Intraday]

    enum CodingKeys: String, CodingKey {
        case symbol
        case stockExchangeShort = "stock_exchange_short"
        case timezoneName = "timezone_name"
        case intraday
    }
}

struct Intraday: Decodable {
    let intradayOpen: String
    let close: String
    let high: String 
    let low: String
    let volume: String

    enum CodingKeys: String, CodingKey {
        case intradayOpen = "open"
        case close
        case high
        case low 
        case volume
    }
}
