  public   partial   class 登录：PhoneApplicationPage

  public  Login（）
 {
 InitializeComponent（）; 
} 
 
  private   void  Login_Click（ object  sender，RoutedEventArgs e）
 {
 SendRequest（Box_email.Text，PasswordBox.Password）; 
} 
 
  public   void  SendRequest（ String  email， String  mdp）
 {
  //  创建一个新的HttpWebRequest对象。 
 HttpWebRequest request =（HttpWebRequest）WebRequest.Create（  http://19.334.35.55/eip/api/web/app.php/oauth/v2/token？）; 
 
  string  _url =   http://19.334.35.55/eip/api/web/app.php/oauth/v2/token？; 
  string  _email =   Username = +电子邮件; 
  string  _mdp =   password = + mdp; 
 request.ContentType = _url + _email + _mdp; 
 request.Method =   GET;

        }

        public void SendRequest(String email, String mdp)
        {
            // Create a new HttpWebRequest object.
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://19.334.35.55/eip/api/web/app.php/oauth/v2/token?");

            string _url = "http://19.334.35.55/eip/api/web/app.php/oauth/v2/token?";
            string _email = "Username=" + email;

            allDone.WaitOne();
        }


        private void GetResponseCallback(IAsyncResult asynchronousResult)
        {
            //   Dispatcher.BeginInvoke(() =>
            //  {
            //      MessageBox.Show("inside get response");
            // });
            
            HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
            if (request != null)
            {

                try
                {
                    // End the operation
                    HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);

                    Stream streamResponse = response.GetResponseStream();

                    StreamReader streamRead = new StreamReader(streamResponse);
                    string responseString = streamRead.ReadToEnd();
                    Console.WriteLine(responseString);
                    // Close the stream object
                    streamResponse.Close();
                    streamRead.Close();

                    // Release the HttpWebResponse
                    response.Close();
                    allDone.Set();
                }
                catch (WebException e)
