{
"actions" : {
"upvote" : {
"delete" : true,
"read" : true,
"create" : true,
"update": true
},
"read" : {
"delete" : true,
"update" : true,
"read" : true,
"create" : true
}
}
}
我有来自服务器的Json响应,下面是使用Decodable协议创建的模型结构
struct Actions: Decodable {
let upvote: UpvoteStatus
let read: ReadStatus
enum CodingKeys: String, CodingKey {
case upvote
case read
}
init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)
self.upvote = try container.decode(UpvoteStatus.self, forKey: .upvote) {
self.read = try container.decode(ReadStatus.self, forKey: .read)
}
}
struct UpvoteStatus: Decodable {
let delete: Bool
let update: Bool
let read: Bool
let create: Bool
}
struct ReadStatus: Decodable {
var delete: Bool
var update: Bool
var read: Bool
var create: Bool
}
这很好用,但是会创建很多重复的代码,因为UpvoteStatus和ReadStatus结构具有相似的属性,并且来自服务器的JSON相似,只是键不同。
有什么办法可以创建一个通用的状态结构,将状态属性添加到ReadStatus和UpvoteStatus类
struct Status: Decodable {
let delete: Bool
let update: Bool
let read: Bool
let create: Bool
}
现在,我要添加以下内容,以便删除重复的代码。
struct UpvoteStatus: Decodable {
let status: Status
}
struct ReadStatus: Decodable {
let status: Status
}

无需编写自定义初始化程序并显式定义编码键。
您可以简单地写
struct Response: Codable {
let actions: Actions
struct Actions : Codable {
let upvote: Element
let read: Element
struct Element: Codable {
let delete: Bool
let read: Bool
let create: Bool
let update: Bool
}
}
}
