嵌套的Json解碼器Swift

Question

在解碼json時，我得到零響應。 我已經嵌套了json。 無論我不知道，我正在解析正確的方法。 這是我的代碼。

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 pic = "pic"
        case cover = "cover"
        case background = "background"
        case layout = "layout"
        case customcolors
        case widgets = "widgets"
        case basket = "basket"
        case joindate = "joindate"
        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)
    }

}

這也是我的json響應

{“狀態”：1，“消息”：“獲取的數據”，“配置文件”：{“名稱”：“ Prem Kumar”，“電子郵件”：“ a@a.com”，“已驗證”：true，“電話“：” + 91998532542“，” articletype“：[” fun“，” article“，” insight“]，” ai_score“：100，” bfi“：” 100％“，” pic“：”“，” cover“ ：“”，“ background”：“”，“ layout”：“ 3column”，“ customcolors”：{“ text”：“＃e7e7e7”，“ opacity”：“ 0.8”，“ bg”：“＃272323”} ，“小配件”：[“興趣”，“教育”，“興趣”，“媒體”，“習慣”，“職業”，“天氣”，“社交類型”，“訂單歷史”，“報紙”，“國家”， “ wishlist”]，“ basket”：[{“ mood”：“ sadness”，“ score”：5}，{“ mood”：“ fear”，“ score”：4}，{“ mood”：“ anger” ，“得分”：4}，{“心情”：“厭惡”，“得分”：3}，{“心情”：“討厭”，“得分”：3}，{“心情”：“嫉妒”，“ score“：2}，{” mood“：” satisfaction“，” score“：0}，{” mood“：” competetive“，” score“：0}，{” mood“：” frustration“，” score“ ：0}，{“ mood”：“歡樂”，“得分”：0}，{“ mood”：“海拔”，“得分”：0}，{“ mood”：“愛”，“得分”：0 }，{“ mood”：“ energytic”，“ score”：0}]，“ joindate”：“ 2017-12-10T07：50：06.379Z”，“ linklink_id”：“ 5a435b0a5c23904f78b76542”，“ gps”：true， “ radius”：5，“ showme”：true}}

Answer 1

請閱讀錯誤消息。 他們很清楚

• 在Profile中，按鍵phone值為String
• 在CustomColors中，鍵opacity值為String

雙引號中的每個值都是String ，甚至是"0" ， "1.0"和"false"

您可以刪除所有編碼鍵和所有初始化器，因為它們是隱式提供的。 並且不要將所有內容都隨意聲明為可選。 僅將那些屬性聲明為可選，否則其相應的鍵可能會丟失。 此特定的JSON無需任何可選屬性即可工作

Answer 2

就像@vadian正確說的那樣，刪除所有初始化程序，不要將所有內容都聲明為可選的。 確定響應中可能缺少的鍵，並僅將這些鍵聲明為可選鍵。 您提供的JSON不需要任何可選選項。

為了更清楚一點，請檢查以下代碼

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
}
