Swift学习笔记（四）HandyJSON序列化

GitHub：https://github.com/alibaba/HandyJSON

根据返回数据格式进行建Model：

struct WeatherModel: HandyJSON {

    var shidu : String?
    var wendu : String?
    var pm25 : String?
    var pm10 : String?
    var quality : String?
    var yesterday : WeatherListModel?//昨日天气
    var forecast : Array<WeatherListModel>?//未来几天天气
}

struct WeatherListModel: HandyJSON {

    var api : String?
    var type : String?
    var date : String?//日期
    var sunrise : String?//日出
    var sunset : String?//日落
    var high : String?//最高温
    var low : String?//最低温
    var fx : String?//东南风
    var fl : String?//4-5级
}

发起Http请求在成功后block序列化的Model对象

static func weather(city:String, success:((_ model:WeatherModel?) -> Void)?, failure:((_ e:HttpException) -> Void)?) -> Void {

        let requestURL = "https://www.sojson.com/open/api/weather/json.shtml"//接口URL

        var modelR = CityWeatherModelR.init()//入参Model对象
        modelR.city = city//赋值
        let paramer : Dictionary = modelR.toJSON()!//反序列化成Dictionary

        HttpClient.GET(url: requestURL, params: paramer, success: { (responseObj) in

            if let object = WeatherModel.deserialize(from: responseObj) {//序列化成Model
                success!(object)
            }
        }) { (e) in

            failure!(e)
        }
}

在视图控制器中，获取上海市的天气信息：

NetworkAPI.weather(city: "上海", success: { (model) in

    self.dataArr = model?.forecast;//未来几日天气预报数组
    self.tableView.reloadData()
}) { (e) in

    print("获取失败，原因：\(e.message!)");
}

最后附上我写的Demo：https://github.com/Geniune/LearnSwift
