Swift 4解析json数字键，带1+；氮量

我仍在学习Swift 4中JSON解析的新功能

我能够构建一个结构并获取温度键，但是泵和其他类似的项目是数字字符串，可以是1到n。将它们解析为数组或字典的最佳方法是什么。我会假设一个for循环

 public struct ServerReponse: Codable {
    let temperature: Temperature
    let circuit: Circuit 
 }

public struct Circuit: Codable {
    let number: Int
    let numberStr: String
    let name: String
    let circuitFunction: String
    let status: Int
    let freeze: Int
    let delay: Int
    let friendlyName: String
    let light: Light?
}

public struct Light: Codable {
    let pump: Int
    let position: Int
    let colorStr: String
    let color: Int
    let colorSet: Int
    let colorSetStr: String
    let prevColor: Int
    let prevColorStr: String
    let colorSwimDelay: Int
    let mode: Int
    let modeStr: String
}

public struct Temperature : Codable {
    let poolTemp: Int
    let airTemp: Int
    let poolSetPoint: Int
    let heaterActive: Int
    }
...
let poolData = try? JSONDecoder().decode(ServerReponse.self, from: data)
print(poolData?.temperature)

我在解析下一节“电路”时遇到问题，其中可能有1到多个数字键，然后电路会在每一个数字键下面自行构造

下面是我正在使用的一些JSON

键

电路
的值是一个字典

如果需要通过数字快速访问，请将对象解码为
[String:Circuit]

public struct ServerReponse: Codable {
   let temperature: Temperature
   let circuit: [String:Circuit] 
}

如果数组更合适，则编写一个自定义初始值设定项，该初始值设定项还将值映射到数组

public struct ServerReponse: Codable {
    let temperature: Temperature
    let circuits: [Circuit]

    private enum CodingKeys: String, CodingKey { case temperature, circuits = "circuit"}

    public init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        temperature = try container.decode(Temperature.self, forKey: .temperature)
        let circuitData = try container.decode([String:Circuit].self, forKey: .circuits)
        circuits = Array(circuitData.values).sorted(by: {$0.number < $1.number})
    }
}

公共结构ServerResponse:Codable{
让温度：温度
let电路：[电路]
私有枚举编码键：字符串，编码键{case temperature，circuits=“circuit”}
public init（来自解码器：解码器）抛出{
let container=try decoder.container（keyedBy:CodingKeys.self）
温度=尝试容器。解码（temperature.self，forKey:.temperature）
让circuitData=try container.decode（[String:Circuit].self，forKey:.circuits）
电路=数组（circuitData.values）。排序（按：{$0.number<$1.number}）
}
}

public struct ServerReponse: Codable {
    let temperature: Temperature
    let circuits: [Circuit]

    private enum CodingKeys: String, CodingKey { case temperature, circuits = "circuit"}

    public init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        temperature = try container.decode(Temperature.self, forKey: .temperature)
        let circuitData = try container.decode([String:Circuit].self, forKey: .circuits)
        circuits = Array(circuitData.values).sorted(by: {$0.number < $1.number})
    }
}
