Question

I am having problems building an app that can access google accounts. I have the following code that gets the sign in page for google accounts and then the access permissions page is also displayed!. Once i click on “Allow Access” the app is redirected to error page. here are few screenshots so that whoever is trying to help can understand better.. and below is the code that am using

 private void browseGoogle_Loaded(object sender, RoutedEventArgs e)
    {
        string address = "https://accounts.google.com/o/oauth2/auth" +
        "?client_id=" + "*******.apps.googleusercontent.com" +
        "&scope=" + "https://www.googleapis.com/auth/plus.me" +
        "&response_type=code" +
         "&redirect_uri=" + "https://www.****.com/oauth2callback";

        browseGoogle.Navigate(new Uri(address, UriKind.Absolute));

    }

https://accounts.google.com/o/oauth2/approval?as=634f855389bf10ff&hl=en_GB&xsrfsign=APsBz4gAAAAAUHZvwB3xTqisyv8hEcWem5X3eKvwAHN9
this is the URI its navigating to after allow access is selected/clicked. What does this mean?

This is all am doing. My BrowserNavigated Method doesn’t contain any code as of now. I dunno what to do further.hence seeking help.
Please help me resolve this issue.. All answers and suggestion appreciated.

Answer 1

 private void browseGoogle_Loaded(object sender, RoutedEventArgs e)
    { 
        try
        {
            StringBuilder autheticateURL = new StringBuilder();
            autheticateURL.Append(GmailSettings.AuthorizeUri).Append("?client_id=").Append(GmailSettings.clientID).Append("&scope=").
                Append(GmailSettings.ScopeValue).Append("&response_type=code").Append("&redirect_uri=").Append(GmailSettings.CallbackUri);
            browseGoogle.Navigate(new Uri(autheticateURL.ToString(), UriKind.Absolute));
        }
        catch (Exception ex)
        {

            Logger.log(TAG, "browseGoogle_Loaded()", ex.Message);

        }
    }

    /// <summary>
    /// Called when the web browser initiates Navigation to various pages 
    /// </summary>
    /// <param name="sender">Browser</param>
    /// <param name="e">Navigating event arguments</param>
    private void browseGoogle_Navigating(object sender, NavigatingEventArgs e)
    {
        try
        {
            string hostName = e.Uri.Host;
            string URL = e.Uri.ToString();

            if (hostName.StartsWith("localhost"))
            {
                NavigationService.Navigate(new Uri("/HomePage.xaml", UriKind.Relative));
            }
        }
        catch (Exception ex)
        {

            Logger.log(TAG, "browseGoogle_Navigating()", ex.Message);

        }
    }

The XAML goes like this

  <phone:WebBrowser x:Name="browseGoogle" Loaded="browseGoogle_Loaded" IsScriptEnabled="true" Navigating="browseGoogle_Navigating" />

My mistakes were two:-
1) as vignesh has mentioned in his comments I was using a wrong Redirect URI.
2)IsScriptEnabled was not at all set in my Web Browser Controls. Once i set it true everything was fine.
