首先怎麼下載框架我這裡就不說了，進入正題!

首先建立一個NewworkingTools檔案

import AFNetworking
//定義列舉型別
enum RequestType : String {
    case GET = "GET"
    case POST = "POST"
}
class NetworkTools: AFHTTPSessionManager {
   //單例 
    static let shareInstance :NetworkTools = {

        let tools = NetworkTools()
        //這是給JSON序列化加一個格式
 

        tools.responseSerializer.acceptableContentTypes?.insert("text/html")
        return tools
    }()

}
// MARK:- 封裝請求方法
extension NetworkTools {


    func request(methodType : RequestType , urlString : String,parameters :[String : AnyObject],failure :(result : AnyObject? , error : NSError?) -> ()) {
        //判斷是那種請求 GET
 

        if methodType == .GET{
            GET(urlString, parameters: parameters, progress: nil, success: { (stak : NSURLSessionDataTask ,result : AnyObject?) -> Void in
                print(result)
                }, failure: { (task :NSURLSessionDataTask?, error:NSError?) -> Void in
            })
        }
        else
 
 //POST
        {
            POST(urlString, parameters: parameters, progress: nil, success: { (stak : NSURLSessionDataTask, result : AnyObject?) -> Void in

                }, failure: { (task : NSURLSessionDataTask?, error : NSError?) -> Void in
                })
        }
   }
}


}

現在可以在外面試著呼叫了

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        NetworkTools.shareInstance.request(.GET, urlString: "http://httpbin.org/get", parameters: ["name":"MarkTang"]) { (result, error) -> () in

        }
    }

如果你沒有改配置的話，會出現以下錯誤

你需要需要以下info的配置，因為是可能是https

再次執行，你會拿到類似於以下資料

接下來在繼續優化一下程式碼

// MARK:- 封裝請求方法
extension NetworkTools {


    func request(methodType : RequestType , urlString : String,parameters :[String : AnyObject],failure :(result : AnyObject? , error : NSError?) -> ()) {

        //1.定義成功回撥的閉包
        let successCallBack = { (stak : NSURLSessionDataTask ,result : AnyObject?) -> Void in
            //把閉包傳出去
            failure(result: result, error: nil)

        }
        //2.定義失敗的回撥閉包
        let failureCallBack = { (stak : NSURLSessionDataTask? ,error : NSError?) -> Void in
            //把閉包傳出去
            failure(result: nil, error: error)

        }

        //3.判斷是那種請求 GET 傳送請求
        if methodType == .GET{
            GET(urlString, parameters: parameters, progress: nil, success: successCallBack, failure: failureCallBack)
        }
        else //POST
        {
            POST(urlString, parameters: parameters, progress: nil, success: successCallBack, failure: failureCallBack)
        }
   }

}

//在外面可以拿到返回的值
 override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        NetworkTools.shareInstance.request(.GET, urlString: "http://httpbin.org/get", parameters: ["name":"MarkTang"]) { (result, error) -> () in
            if error != nil {
                print(error)
                return
            }

            print(result)
         }
    }

再跑一下,可以返回引數,好了這就是最簡單的封裝了,下次再見，如果有疑問可以在下面回覆，我看到會及時回覆！
