Question

解码json时，我得到了无响应。我已经嵌套了json。我是否不知道，我正在解析正确的方式。这是我的代码。

struct ProfileModelClass : Codable {
    let status : Int?
    let message : String?
    let profile : Profile?

    enum CodingKeys: String, CodingKey {

        case status = "status"
        case message = "message"
        case profile
    }
    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        status = try values.decodeIfPresent(Int.self, forKey: .status)
        message = try values.decodeIfPresent(String.self, forKey: .message)
        profile = try Profile(from: decoder)
    }
}


struct Profile : Codable {
    let name : String?
    let email : String?
    let verified : Bool?
    let phone : Int?
    let articletype : [String]?
    let ai_score : Int?
    let bfi : String?
    let pic : String?
    let cover : String?
    let background : String?
    let layout : String?
    let customcolors : Customcolors?
    let widgets : [String]?
    let basket : [Basket]?
    let joindate : String?
    let linklink_id : String?
    let gps : Bool?
    let radius : Int?
    let showme : Bool?

    enum CodingKeys: String, CodingKey {

        case name = "name"
        case email = "email"
        case verified = "verified"
        case phone = "phone"
        case articletype = "articletype"
        case ai_score = "ai_score"
        case bfi = "bfi"

        case linklink_id = "linklink_id"
        case gps = "gps"
        case radius = "radius"
        case showme = "showme"
    }

    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        name = try values.decodeIfPresent(String.self, forKey: .name)
        email = try values.decodeIfPresent(String.self, forKey: .email)
        verified = try values.decodeIfPresent(Bool.self, forKey: .verified)
        phone = try values.decodeIfPresent(Int.self, forKey: .phone)
        articletype = try values.decodeIfPresent([String].self, forKey: .articletype)
        ai_score = try values.decodeIfPresent(Int.self, forKey: .ai_score)
        bfi = try values.decodeIfPresent(String.self, forKey: .bfi)
        pic = try values.decodeIfPresent(String.self, forKey: .pic)
        cover = try values.decodeIfPresent(String.self, forKey: .cover)
        background = try values.decodeIfPresent(String.self, forKey: .background)
        layout = try values.decodeIfPresent(String.self, forKey: .layout)
        customcolors = try Customcolors(from: decoder)
        widgets = try values.decodeIfPresent([String].self, forKey: .widgets)
        basket = try values.decodeIfPresent([Basket].self, forKey: .basket)
        joindate = try values.decodeIfPresent(String.self, forKey: .joindate)
        linklink_id = try values.decodeIfPresent(String.self, forKey: .linklink_id)
        gps = try values.decodeIfPresent(Bool.self, forKey: .gps)
        radius = try values.decodeIfPresent(Int.self, forKey: .radius)
        showme = try values.decodeIfPresent(Bool.self, forKey: .showme)
    }

}

struct Basket : Codable {
    let mood : String?
    let score : Int?

    enum CodingKeys: String, CodingKey {

        case mood = "mood"
        case score = "score"
    }

    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        mood = try values.decodeIfPresent(String.self, forKey: .mood)
        score = try values.decodeIfPresent(Int.self, forKey: .score)
    }

}

struct Customcolors : Codable {
    let text : String?
    let opacity : Double?
    let bg : String?

    enum CodingKeys: String, CodingKey {

        case text = "text"
        case opacity = "opacity"
        case bg = "bg"
    }

    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        text = try values.decodeIfPresent(String.self, forKey: .text)
        opacity = try values.decodeIfPresent(Double.self, forKey: .opacity)
        bg = try values.decodeIfPresent(String.self, forKey: .bg)
    }

}

这是我的json回复

Answer 1

请阅读错误消息。他们很清楚

在Profile中，密钥phone的值为String
在CustomColors中，密钥opacity的值为String

双引号中的每个值都是String，甚至是"0"，"1.0"和"false"

您可以删除所有编码密钥和所有初始化程序，因为它们是隐式提供的。并且不要随意声明一切都是可选的。仅将那些属性声明为可选，其相应的键可能会丢失。此特定JSON在没有任何可选属性的情况下工作

Answer 2

正如@vadian正确地说的那样，删除所有的初始化程序，并且不要将所有内容声明为可选的直接。确定响应中可能缺少的键，并仅将这些键声明为可选项。您提供的JSON不需要任何选项。

为了更清楚，请查看以下代码

struct ProfileModelClass : Codable {
    let status : Int
    let message : String
    let profile : Profile
}

struct Profile : Codable {
    let name : String
    let email : String
    let verified : Bool
    let phone : String
    let articletype : [String]
    let ai_score : Int
    let bfi : String
    let pic : String
    let cover : String
    let background : String
    let layout : String
    let customcolors : Customcolors
    let widgets : [String]
    let basket : [Basket]
    let joindate : String
    let linklink_id : String
    let gps : Bool
    let radius : Int
    let showme : Bool
}

struct Customcolors : Codable {
    let text : String
    let opacity : String
    let bg : String
}

struct Basket : Codable {
    let mood : String
    let score : Int
}
