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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

/// 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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

//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()

　　}

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13

/// 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()     } }
