swift - 网络请求数据处理 - 协议处理

1. 在类的模型之中或类的结构体 里面 实现下面方法

/// 添加预约数据源模型 - rootModel
class DataModelForAddNewBespeakModel: NSObject {

    /// 返回新增预约界面 cell数量 目前就3个
    var cellCount = 3

    /// 顾客模型
    var customerModel = Mapper<JYCustomerListItemModel>().map(JSONObject: "默认是空的")

    /// 时间和发型师 的组合
    var timeModelAndHairdresserModel = TimeModelAndHairdresserModel()

    /// 选择的项目 - 传给后台的数据
    var itemsModel = ItemsModel()

    /// phz 传给我的原生的数据 JYBespekSelectItemModel
    var originalDataForItemsModel = [JYBespekSelectItemModel]()

    /// 新增预约需要的参数  这是关键 的一个
    func paramsForNewAddBespeak() -> [String: Any] {
        return ["crm_customer_ID": self.customerModel?.customerId ?? "",
                "BookingDate" : self.timeModelAndHairdresserModel.timeModel.selectedDateModel.yearMonthDay ,
                "StartTime" : self.timeModelAndHairdresserModel.timeModel.bookTime ,
                "ServiceEmployee" : self.timeModelAndHairdresserModel.hairdresserModel?.employeeId ?? "",
                "ServiceItemGroupID" : self.itemsModel.groupId ,
                "Remark" : "备注",
                "itemIds" : self.itemsModel.projectIdArr] as [String: Any]
    }
}

　　
2. 协议的实现

//MARK: 纯功能性协议：BespeakRequestProtocol(保证控制器拥有这个方法)， 必须实现 业务处理协议：JYServiceNetworkProtocol(请求失败和请求成功的业务处理)
protocol BespeakRequestProtocol{}
extension BespeakRequestProtocol where Self: UIViewController {

    /// 新增预约请求
    func requestForNewAddBespeak(params:[String:Any], type:JYServiceNetworkProtocol)  {
        JYRequestAlamofire.request(method: JYHTTPMethod.post, url: JY_API_ADD_BESPEAK, params: params, handleSuccess: { (result) in
            let model = Mapper<QueryBespeakModel>().map(JSONObject: result)
            if model?.ret == "0"{
                type.operationSuccess(data: [:], identifier: "func requestForNewAddBespeak")
            }else{
                type.serverShowErr(err: model?.msg, identifier: "func requestForNewAddBespeak")
            }
        }) { (err) in
            type.serverShowErr(err: "暂无网络", identifier: "func requestForNewAddBespeak")
        }
    }
}

　
3. 控制器调用

 

　　class JYAddNewBespeakVC: JYBaseVC {

　　/// 页面所有数据模型

　　var dataModel = DataModelForAddNewBespeakModel()

　　}

3.1 

    //点击确定按钮
    @IBAction func clickSureBespeakBtn(_ sender: Any) {

        view.showHud()
        self.requestForNewAddBespeak(params: self.dataModel.paramsForNewAddBespeak(), type: self)

    }

3.2 实现协议

extension JYAddNewBespeakVC:BespeakRequestProtocol, JYServiceNetworkProtocol{

    func serverShowErr(err: String?, identifier: String?) {
        view.showTipsInfo(tips: err)
    }

    func operationSuccess(data: [String : Any]?, identifier: String?) {
        view.hiddenHUd()
　　　　"请求成功做的事情"
    }
}

4.因为本身是controller 遵循的协议, 可以获得view的属性

    /// 取消预约请求
    func requestForCancleBespeak(bespeakId : String, ProtocolFollower:JYServiceNetworkProtocol){

        view.showHud()
        let parameters = ["ID" : bespeakId]
        weak var weakSelf = self
        JYRequestAlamofire.request(method: .put, url:JY_API_CANCLE_BESPEAK , params: parameters, handleSuccess: { [weak self] (res) in

        }) { [weak self] (_) in
            self?.view.loseNetWorkDismissToast()
        }
    }
