 @IBAction func btnget(_ sender: UIButton) {

    let urlpath : String = "http://202.131.123.211/UdgamApi_v4/App_Services/UdgamService.asmx/GetAllTeacherData?StudentId=2011111"

    let url = URL(string: urlpath)

    var urlrequest = URLRequest(url: url!)

    urlrequest.httpMethod = "GET"

    let config = URLSessionConfiguration.default
    let session = URLSession(configuration: config)

    let task = session.dataTask(with: urlrequest) { (data, response, error) in

        do {
            guard let getResponseDic = try JSONSerialization.jsonObject(with: data!, options: []) as? [String: AnyObject] else {
                print("error trying to convert data to JSON")
                return
            }
            // now we have the todo, let's just print it to prove we can access it

            print(getResponseDic as NSDictionary)

            let dic = getResponseDic as NSDictionary
            let msg = dic.object(forKey: "message")

            print(dic)
            //let arrObj = dic.object(forKey: "teacherDetail") as! NSArray
            //print(arrObj)

            //let arr = dic.value(forKey: "TeacherName")as! NSArray

            print(((dic.value(forKey: "teacherDetail") as! NSArray).object(at: 0) as! NSDictionary).value(forKey: "TeacherName") as! String)

            // the todo object is a dictionary
            // so we just access the title using the "title" key
            // so check for a title and print it if we have one

            // print("The title is: " + todoTitle)
        } catch  {
            print("error trying to convert data to JSON")
            return
        }
    } task.resume()
}
