作ってもらった。
alamofirをimportしている。

                   print(jsonData)

                    //if there is no error
                }
        }
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

Alamofire.request(URL, method: .get, parameters: nil).responseJSON　か。
alamofireのframe workを入れるところと、getだから、postの場合どうするかだね。
