获取API Swift

Question

以前，我正在处理的API如下所示

{
  "kurumsicilno": 457.0,
  "yillikizin": 30.0,
}

我的模型如下所示

struct Leave: Decodable, Identifiable {
    var id: Double? {
        return registerNumber
    }
    let registerNumber: Double
    let annualLeave: Double
    
    enum CodingKeys: String, CodingKey {
        case registerNumber = "kurumsicilno"
        case annualLeave = "yillikizin"
    }
}

这是我的网络功能

 let task = session.dataTask(with: request) { (data, response, error) in
            if error == nil {
                let decoder = JSONDecoder()
                if let safeData = data {
                    do {
                        let result = try decoder.decode(Leave.self, from: safeData)
                        DispatchQueue.main.async {
                            completion(result)
                        }
                    } catch {
                        print(error)
                    }
                }
            }
        }
        task.resume()

但出于某种原因，他们已将API更改为此。

{
"isSucceed": true,
"singleData": {
    "sicilNo": "457",
    "yillikIzin": "30",
},

我应该如何修改我的模型，这样我才能像以前一样到达并获取数据？

Answer 1

只需创建一个新的根结构

struct Response : Decodable {
   let isSucceed: Bool
   let singleData: Leave
}

并且您必须更改类型和( CodingKeys之一)

struct Leave: Decodable, Identifiable {
    var id: String { // no Optional!!
        return registerNumber
    }
    let registerNumber: String
    let annualLeave: String
    
    enum CodingKeys: String, CodingKey {
        case registerNumber = "sicilNo"
        case annualLeave = "yillikIzin" // is this really a capital `I`?
    }
}

最后更改解码码

let result = try decoder.decode(Response.self, from: safeData)
      DispatchQueue.main.async {
          completion(result.singleData)
      }

您可能必须在其他代码中管理类型更改双→字符串。
