首先怎么下载框架我这里就不说了，进入正题!

首先创建一个NewworkingTools文件

import AFNetworking//定义枚举类型enum RequestType : String {    case GET = "GET"    case POST = "POST"}class NetworkTools: AFhttpSessionManager {   //单例     static let shareInstance :NetworkTools = {        let tools = NetworkTools()        //这是给JsON序列化加一个格式        tools.responseSerializer.acceptableContentTypes?.insert("text/HTML")        return tools    }()}// MARK:- 封装请求方法extension NetworkTools {    func request(methodType : RequestType,urlString : String,parameters :[String : AnyObject],failure :(result : AnyObject?,error : NSError?) -> ()) {        //判断是那种请求 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,result : AnyObject?) -> VoID in                },failure: { (task : NSURLSessionDataTask?,error : NSError?) -> VoID in                })        }   }}}

现在可以在外面试着调用了

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

如果你没有改配置的话，会出现以下错误

你需要需要以下info的配置，因为是可能是https

再次运行，你会拿到类似于以下数据

接下来在继续优化一下代码

// MARK:- 封装请求方法extension NetworkTools {    func request(methodType : RequestType,error : NSError?) -> ()) {        //1.定义成功回调的闭包        let successCallBack = { (stak : NSURLSessionDataTask,result : AnyObject?) -> VoID in            //把闭包传出去            failure(result: result,error: nil)        }        //2.定义失败的回调闭包        let failureCallBack = { (stak : NSURLSessionDataTask?,error : NSError?) -> VoID in            //把闭包传出去            failure(result: nil,error: error)        }        //3.判断是那种请求 GET 发送请求        if methodType == .GET{            GET(urlString,success: successCallBack,failure: failureCallBack)        }        else //POST        {            POST(urlString,failure: failureCallBack)        }   }}//在外面可以拿到返回的值 overrIDe func touchesBegan(touches: Set<UItouch>,error) -> () in            if error != nil {                print(error)                return            }            print(result)         }    }
