swift网络请求 swift同样可以实现OC中AFNetworking+MJExtension的效果，实现方法是Alamofire+SwiftyJSON+HandyJSON

Alamofire：网络请求 SwiftyJSON：数据解析 HandyJSON：映射为model

一、获取SessionManager子类的单例

节约系统开支不用每次网络请求都生成一个SessionManager子类对象

import UIKit
import Alamofire


/// 网络配置单例类
class TMNetManager: SessionManager {
    
    static var theManager:TMNetManager?
    
    class func shareManager(timeOutFlo:TimeInterval = 60) -> TMNetManager {
        
        let config = Config.shareConfig()
        config.timeoutIntervalForRequest = timeOutFlo
        
        if theManager == nil{
            theManager = TMNetManager.init(configuration: config)
        }

        return theManager!
    }
    
}





/// 网络配置单例类
class Config: URLSessionConfiguration {
    static var theConfig:URLSessionConfiguration?
    class func shareConfig() -> URLSessionConfiguration {
        if theConfig == nil {
            theConfig = URLSessionConfiguration.default
        }
        return theConfig!
    }
}

二、网络请求

                        }
                        
                    }

                        fail(json["message"].string ?? kNetFailMessage, response.error ?? NSError.init())
                    }
                    
                }else{ //没有获取到数据
                    fail(kNetFailMessage, NSError.init())
                }
            }else {//网络请求失败
                fail(kNetFailMessage, NSError.init())
            }
        }
        
        
    }
    
    
    
    
    
    
}

三、使用

新建model类

//
//  TMMineModel.swift
//  ivygateSwift
//
//  Created by 纪志刚 on 2018/4/24.
//  Copyright © 2018年 纪志刚. All rights reserved.
//

import UIKit
import HandyJSON



class TMMineModel: HandyJSON {
    
    var code:String = ""
    var name:String = ""
    var domain:String = ""
    var captcha:Bool = false
    
    
    
    
    

    //HandyJSON要求必须实现这个方法
    required init() {
        
    }
    

    
    
    
    
    
    
    /// 获取个人信息
    ///
    /// - Parameters:
    ///   - succ: <#succ description#>
    ///   - fail: <#fail description#>
    static func requestFun(succ: @escaping(_ arr:Array<TMMineModel>) -> (), fail: @escaping (_ errStr: String) -> ()) {
        
        TMNetworkingTool.requestFun(url: "你自己的网络请求", method: kHTTPMethodGet, parameters: nil, showLoading: false, succ: { (responseData, response) in
            succ([TMMineModel].deserialize(from: responseData, designatedPath: "data") as? Array<TMMineModel> ?? Array.init())
        }) { (errStr, err) in
            fail(errStr)
        }
    }
    

}

使用方法

        TMMineModel.requestFun(succ: { (model) in
            print("网络请求成功了")
        }) { (errStr) in
            print("失败了")
        }

image

可以看到网络请求成功之后返回了一个数组，数组内是自定义数据类型

HandyJSON用于数据映射时注意

  1. model类继承自HandyJSON并实现init方法
    //HandyJSON要求必须实现这个方法
    required init(){}

2.重命名属性时实现方法

    func mapping(mapper: HelpingMapper) {
        mapper <<<
            self.ID <-- "id"
        mapper <<<
            self.Description <-- "description"
    }

3.映射为model类和映射为model数组的用法分别为

TMMineSaleStatusModel.deserialize(from: jsonStr, designatedPath: kNet_data_Key) ?? TMMineSaleStatusModel.init()

[TMMineSaleStatusModel].deserialize(from: jsonStr, designatedPath: kNet_data_Key) as? Array<TMMineSaleStatusModel> ?? Array.init()
