swift - 如何从 OpenWeatherMap 解析 "Rain"？

Question

当从 OpenWeatherMap API 实现 Rain 时，我遇到了这个错误:

'h' 不是整数文字中的有效数字

我有一个单独的 .swift 文档来解析所有 API 引用，并尝试像这样解析 Rain:

struct Rain: Decodable {
let 3h: Double?
}

但我不确定如何解决“Rain: 3h”这样错误就不会发生。？

有人可以看看 OpenWeatherMap API 并告诉我他们的想法吗？

更新:

结构.swift:

struct Rain: Decodable {
enum CodingKeys: String, CodingKey { case threeHours = "3h" }

let threeHours: Double?
}

ViewController.swift

@IBOutlet weak var precipitation: UILabel!


let clouding = (self.rain?.threeHours!)!
precipitation.text = precipitation.text! + "  " + String(format:"%.0f", clouding)

Answer 1

只需通过 CodingKeys 翻译 key

struct Rain: Decodable {
    enum CodingKeys: String, CodingKey { case threeHours = "3h" }

    let threeHours: Double?
}

或

struct Rain: Codable {
    enum CodingKeys: String, CodingKey { case h3 = "3h" }

    let h3: Double?
}
