Alamofire 的简单封装

这里简单的介绍一下Alamofire，同时将简单的分装分享给大家
首先给大家一手资料，免得大家东找西找，等再次使用的话又开始盲目的再找一次，然后后面重复很多次，因此建议大家收藏和学习最好从第一手资料开始，免得被误解，如果看不懂可以借鉴别人的分解。

Alamofire 的Github的一首资料，拿到后有些人会发现，唉怎么没有分享怎么使用，哈哈哈，为此再进一步 使用教程，如果感觉还是不够直接，大家可以参考Alamofire框架的使用一基本用法分解，比较详细，如果感觉还是比较困难，那我只能简单分享一下我这里的封装，为此大家借鉴一下，如果更好的方法还望推荐，谢谢！

【Model】

import UIKit
import Alamofire

class NetworkModel: NSObject {
    var urlString:String! = ""
    var methodType:HTTPMethod! = .get
    var parameters:[String: String]?
    var isAnimation:Bool = true
}

【Alamofire封装】其实简单的APP足够用啦

import UIKit
import Alamofire

class NetworkManager: NSObject {
    var alamofire:SessionManager?
}

extension NetworkManager {
    //单例
    static let sharedNetworkManager: NetworkManager = {
        let share = NetworkManager()
        let configuration = URLSessionConfiguration.default
        configuration.timeoutIntervalForRequest = 10 //时间超时
        share.alamofire = Alamofire.SessionManager(configuration: configuration)
        return share
    }()
    //方法
    func requestData(urlString:String, methodType:HTTPMethod, parameters:[String: String]?, finished:@escaping (_ result: AnyObject?, _ error: NSError?) -> ()) {
        self.alamofire?.request(urlString, method: methodType, parameters: parameters, encoding: URLEncoding.default)
            .responseJSON { response in
                
                if response.result.isSuccess {
                    debugPrint(response.result)
                    finished(response.result.value as AnyObject?, nil)
                } else {
                    finished(nil, response.result.error as NSError?)
                }
        }
    }
}

【使用和针对性APP使用】

import UIKit
import Alamofire
import CryptoSwift
import SwiftyJSON
import SwiftProgressHUD


enum NetworkActionType {
    case None                           //空
    
    case LoginIn                        //登录   
}


class JDNetwork: NSObject {
    //MARK - 参数
    var networkModel:NetworkModel?
    var actionType:NetworkActionType = .None

//MARK - 获取接口数据
extension JDNetwork {
    func getDataRequest(finished:@escaping (_ result: AnyObject?, _ error: NSError?) -> ()) {
        if self.networkModel!.isAnimation {
            SwiftProgressHUD.showWait()
        }
        let urlStr = APPHttp + "/" + self.networkModel!.urlString
        
        NetworkManager.sharedNetworkManager.requestData(urlString: urlStr, methodType: self.networkModel!.methodType!, parameters:self.networkModel!. parameters, finished: {(result, error) in
            SwiftProgressHUD.hideAllHUD()
            if result != nil  && error == nil {
                let data = self.handleData(result: result!)
                finished(data.0, data.1)
            } else {
                finished(nil, error)
                SwiftProgressHUD.show("网络请求失败", type: SwiftProgressHUDType.fail, autoClear: true, autoClearTime: 2)
            }
        })
    }
}


//MARK: handleData
extension JDNetwork {
    func handleData(result:AnyObject) -> (AnyObject?, NSError?){
        //返回值
        var object:AnyObject?
        var error: NSError?
        
        let dict =  result as! Dictionary<String, Any>
        let code = dict["code"] as? String
        //token超时，退出登录
        if code == "20000" {
            //退出 删除数据
            appDelegate.setLoginRootVC()
            //提示信息
            if let msg = dict["message"] as? String {
                SwiftProgressHUD.show(msg, type: SwiftProgressHUDType.fail, autoClear: true, autoClearTime: 2)
            }
        }
        else if code == "00000" { //正常返回
            switch self.actionType {
            case .None: break
                
            case .LoginIn:
                object = JDNetworkData.saveUserInfo(result: result) as AnyObject
            }
        }
        //错误返回
        else {
            if let msg = dict["message"] as? String {
                SwiftProgressHUD.showOnlyText(msg)
                DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
                    SwiftProgressHUD.hideAllHUD()
                }
                error = NSError(domain: msg, code: 9999, userInfo: nil)
            }
        }
        
        return (object, error)
    }
}

【产品Model】

import UIKit
class JDProductModel: JDModel {
    var id: Int = 0
    var name:String = ""
}

【数据处理】

import UIKit
import SwiftyJSON

class JDNetworkData: NSObject {
    //可以使用SwiftyJSON来做类型转换
    static func saveUserInfo(result:AnyObject?) -> JDUser? {
        let json = JSON(result!)
        let dict = json.dictionaryValue["data"]?.dictionaryObject
        let user = JDUser.deserialize(from: dict)
        return user
    }
   
    //也可以使用swift的可选功能进行数据解析
    static func handleProductListData(result:AnyObject?) ->(Int,Array<JDProductModel>) {
        var products: Array<JDProductModel> = []
        var count = 0
        if let dict = result as? Dictionary<String, AnyObject> {
            if let data = dict["data"] as? Dictionary<String, AnyObject> {
                count = data["count"] as! Int
                if let list = data["list"] as? Array<Dictionary<String, String>> {
                    for productDict in list {
                        let model = JDProductModel.deserialize(from: productDict)
                        products.append(model!)
                    }
                }
            }
        }
        return (count, products)
    }
}

【使用实例】

//MARK: - Network
    func loginRequest() {
        let network = JDNetwork()
        network.actionType = .LoginIn
        
        let model = NetworkModel()
        model.methodType = .post
        model.urlString = "app/ym/account.ashx"
        model.parameters = ["action":"login",
                            "username":self.loginView.accountView.field.text!,
                            "pwd":self.loginView.passwordView.field.text!]
        network.networkModel = model

        network.getDataRequest { (result, error) in
            if result != nil {
                //数据处理
                let user = result! as! JDUser
            }
        }
    }
