let paramString = "data=Hello"
request.httpBody = paramString.data(using: String.Encoding.utf8)

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

    guard let data = data, let _:URLResponse = response  where error == nil else {
        print("error")
        return
    }

    let dataString =  String(data: data, encoding: String.Encoding.utf8)
    print(dataString)

}

task.resume()
