问题描述
我想将 JSON 嵌套数组解析为我的可分解结构,但问题是没有键值,我该如何将其设置为可分解的结构.我还使用SwiftJSON来解析项目中的对象...
I want to parse the JSON nested array into my decodable struct but the issue is there is no Key values how can i set into my decodable struct. I am also using SwiftJSON to parse object in my project...
这是我的可分解结构:
struct PlayerData: Decodable { let playerID: Int? let platIDRef: Int? let EnrolledDateTime: String? let PlayerType: String? let LastCheckIn: Double? let SerialNo: Int? let Offered: Double? let PlayerReferralCode: Int? let PlayerStats: Double? let PlayerUpstream: Int? }这是控制台中的服务器响应JSON对象:
here is the server response JSON object in console:

要解码数组,您需要获取unkeyedContainer()并分别解码每个值
To decode an array you need to get the unkeyedContainer() and decode each value separately
