Hello !
I use TweetSharp for WP7.1 and I have a problem during the Authentication.
In my page Connexion.xaml there is a WebBrowser Control, a TextBox named Pin and the button Connect.
service, Request and Access are declared in App.xaml.cs respectively as a TwitterService, an OAuthRequestToken and an OAuthAccessToken.
Code of Connexion.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;
using TweetSharp;
namespace CeCertainMoment
{
public partial class Connexion : PhoneApplicationPage
{
public Connexion()
{
InitializeComponent();
//Ask the Token and display the Twitter web page for the authorization
App.service.GetRequestToken((request, Response) =>
{
if (Response.StatusCode == HttpStatusCode.OK)
{
App.Request = request;
Uri uri = App.service.GetAuthorizationUri(request);
System.Windows.Deployment.Current.Dispatcher.BeginInvoke(() =>
{ LoginBrowser.Navigate(uri); });
}
});
}
private void Connect_Click(object sender, RoutedEventArgs e)
{
//Verify the entry of the user
App.service.GetAccessToken(App.Request, Pin.Text, (access, Response) =>
{
if (Response.StatusCode == HttpStatusCode.OK)
{
App.Access = access;
System.Windows.Deployment.Current.Dispatcher.BeginInvoke(() =>
{ NavigationService.Navigate(new Uri("/Composition.xaml", UriKind.Relative)); });
}
});
}
}
}
I don’t know if the problem is in GetRequestToken or in the GetAccessToken :
- when I put a wrong Pin number, nothing happens.
- when I put a empty or the right Pin number, I’m redirected to Composition.xaml and if I try to Tweet I have a NullReferenceException on the AuthenticateWith method.
Code of Composition.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using TweetSharp;
namespace CeCertainMoment
{
public partial class Composition : PhoneApplicationPage
{
public Composition()
{
InitializeComponent();
}
private void Envoi_Click(object sender, RoutedEventArgs e)
{
App.service.AuthenticateWith(App.Access.Token, App.Access.TokenSecret);
App.service.SendTweet((Intro.Text + tweet.Text), (Status, Response) =>
{
if (Response.StatusCode == HttpStatusCode.OK)
{
MessageBox.Show("Tweet Sent !");
}
});
}
}
}
I’m a little lost with this NullReferenceException because during the initialisation of the application, in App.xaml.cs, I initialize service, Request and Access.
Thanks for your help !
