ios - 使用 Codable 在 swift 4.2 中解析 Json

Question

我正在开发一个项目。我从 API 得到了一个响应。现在我想通过使用可解码类的结构的 JsonDecode().decod 函数获取该响应。

我已经制作了可编码的结构，但它给了我这样的错误:

无法读取数据，因为格式不正确。

我的 API 响应是:

{
    auth = 1;
    data =     {
        "dealer_rating" =         {
            average = "3.5";
            "average_width" = "70%";
            count = 2;
            dislikes = 0;
            likes = 2;
            rate1 = 4;
            "rate1_label" = "Atenci\U00f3n al cliente";
            "rate1_width" = "80%";
            rate2 = "3.5";
            "rate2_label" = "Proceso de compra";
            "rate2_width" = "70%";
            rate3 = 3;
            "rate3_label" = "Experiencia general";
            "rate3_width" = "60%";
        };
        review =         (
                        {
                average = 3;
                "post_author" = 16;
                "post_content" = "Test of iOS developer.";
                "post_title" = "iOS Test";
                rate1 = 3;
                "rate1_label" = "Atenci\U00f3n al cliente";
                rate2 = 3;
                "rate2_label" = "Proceso de compra";
                rate3 = 3;
                "rate3_label" = "Experiencia general";
                "stm_recommended" = yes;
                username = "";
            },
                        {
                average = 4;
                "post_author" = 22;
                "post_content" = vvvvvvvvvv;
                "post_title" = vvvvvvvvvv;
                rate1 = 5;
                "rate1_label" = "Atenci\U00f3n al cliente";
                rate2 = 4;
                "rate2_label" = "Proceso de compra";
                rate3 = 3;
                "rate3_label" = "Experiencia general";
                "stm_recommended" = yes;
                username = Vnn;
            }
        );
    };
    message = "Review found.";
    status = 1;
}

我的可解码结构是:

struct resDelerReview : Codable {
    struct struDataString : Codable {
        var average:String?
        var rate1:Int
        var rate1_label:String?
        var rate2:Int
        var rate2_label:String?
        var rate3:Int
        var rate3_label:String?
        var likes:Int
        var dislikes:Int
        var count:Int
        var rate1_width:String?
        var rate2_width:String?
        var rate3_width:String?
        var average_width:String?
    }

    struct struReviewList : Codable {
        var post_author:String?
        var username:String?
        var post_content:String?
        var post_title:String?
        var rate1:String?
        var rate1_label:String?
        var rate2:String?
        var rate2_label:String?
        var rate3:String?
        var rate3_label:String?
        var stm_recommended:String?
        var average:Int
    }


    struct reviewRating : Codable {
        let dealer_rating:struDataString
        let review:[struReviewList]
    }

    let data:reviewRating
    let status:Bool
    let auth:Bool
    let message:String?
}

postman 以文本形式回复

            }
        ]
    },
    "status": true,
    "auth": true,
    "message": "Review found."
}

我的 postman 回复是:

请帮助我，我陷入困境。

如果您阅读整个错误，错误就非常清楚了，属性 rate2 被声明为 Int，但其中一个元素包含 3.5

因此将 struDataString 结构中的它更改为

var rate2: Double

注意还有其他几个类似的字段，例如 struDataString 中的rate2，这些字段很可能包含 double 值，就像其他rateX字段。您可能想查看所有这些的文档
