使用对象映射器解析嵌套的字典数组

Question

我正在解析网络 api 响应，它是一个字典数组。每个字典依次有一个嵌套的字典数组。我如何解析它？请提供一些代码示例。

我的 api 回复是，

(
            {
        FilingStatusId = 0;
        FormName = "MISC";
        OrderId = 0;
        RecipientList =             (
                           {
                FilingStatusId = 0;
                FormId = 1;
                FormName = "MISC";
                PayerId = 26142;
                PayerName = bsbbshs;
                RecipientId = 221438;
                RecipientName = tests;
                ReturnId = 209998;
                UserId = 0;
            },
                          {
                FilingStatusId = 0;
                FormId = 1;
                FormName = "MISC";
                PayerId = 26142;
                PayerName = bsbbshs;
                RecipientId = 221438;
                RecipientName = tests;
                ReturnId = 209998;
                UserId = 0;
            }
        );
    },
        {
        FilingStatusId = 0;
        FormName = "MISC";
        OrderId = 0;
        RecipientList =             (
                           {
                FilingStatusId = 0;
                FormId = 1;
                FormName = "MISC";
                PayerId = 26142;
                PayerName = bsbbshs;
                RecipientId = 221438;
                RecipientName = tests;
                ReturnId = 209998;
                UserId = 0;
            },
                          {
                FilingStatusId = 0;
                FormId = 1;
                FormName = "MISC";
                PayerId = 26142;
                PayerName = bsbbshs;
                RecipientId = 221438;
                RecipientName = tests;
                ReturnId = 209998;
                UserId = 0;
            }
        );
    }
);

到目前为止我的代码是，

这是我的整个响应模型 - ReturnModel

import UIKit
import ObjectMapper

class ReturnModel: Mappable
{
var FilingStatusId : Int = 0
var FormName : String = ""
var OrderId : String = ""
var RecipientList:[[String:Any]]  = [[:]]

required init?(map: Map) {

}

func mapping(map: Map)
{
    FilingStatusId <- map["FilingStatusId"]
    FormName <- map["FormName"]
    OrderId <- map["OrderId"]
    RecipientList <- map["RecipientList"]
}
}

到目前为止，我正在将 RecipientList 解析为字典。但我有另一个名为 RecipientModel 的模型。我如何在此 ReturnModel 中使用它来解析 RecipientList？

Answer 1

Objectmapper 处理嵌套对象，只要它们符合 Mappable:

    import UIKit
    import ObjectMapper

    class ReturnModel: Mappable
    {
    var FilingStatusId : Int = 0
    var FormName : String = ""
    var OrderId : String = ""
    var RecipientList:[RecipientModel] = []

    required init?(map: Map) {

    }

    func mapping(map: Map)
    {
        FilingStatusId <- map["FilingStatusId"]
        FormName <- map["FormName"]
        OrderId <- map["OrderId"]
        RecipientList <- map["RecipientList"]
    }
    }

Answer 2

您的第一个模型将代表外部数组。第二个将代表内部数组。这是一个示例

 import Foundation
 import ObjectMapper


// RecipientModel is an array itself
class RecipientModel: Mappable {

var filingStatusId:Int
var orderId: Int
var formName: String
var recipientList: [RecipientList]

required init?(_ map: Map) {

    filingStatusId = 0
    orderId = 0
    formName = ""
    recipientList = []
}

func mapping(map: Map) {

    filingStatusId      <- map["FilingStatusId"]
    orderId             <- map["OrderId"]
    formName            <- map["FormName"]
    recipientList       <- map["RecipientList"]
}
}

现在您将为 RecipientList 创建另一个模型

class RecipientList: Mappable {


var filingStatusId:Int
var formId: Int
var formName: String

required init?(_ map: Map) {

    filingStatusId = 0
    formId = 0
    formName = ""
}

func mapping(map: Map) {

    filingStatusId      <- map["FilingStatusId"]
    formId              <- map["FormId"]
    formName            <- map["FormName"]
}
}
