我是新來的Facebook C#sdk。我遵循this link的教程。使用Facebook錯誤使用WPF Web瀏覽器的C#sdk
我創建的顯示在登錄後的用戶名的應用程序下面是我的代碼:
public partial class MainWindow : Window
{
private string appId = "appid";
private string extenededPermissions = "offline_access,publish_stream";
private Uri loginUrl = null;
private string accessToken = null;
private string userName = null;
public MainWindow()
{
InitializeComponent();
}
/// <summary>
/// Function to get the login url
/// with the requested permissions
/// </summary>
private void GetLoginUrl()
{
dynamic parameters = new ExpandoObject();
// add the client id
parameters.client_id = appId;
// add the redirect uri
parameters.redirect_uri = "https://www.facebook.com/connect/login_success.html";
// requested response
parameters.response_type = "token";
// type of display
parameters.display = "popup";
// If extended permissions are present
if (!string.IsNullOrWhiteSpace(extenededPermissions))
parameters.scope = extenededPermissions;
// Create the login url
Facebook fc = new FacebookClient();
loginUrl = fc.GetLoginUrl(parameters);
}
private void WindowLoaded(object sender, RoutedEventArgs e)
{
// get the login url
GetLoginUrl();
// Navigate to that page
webBrowser.Navigate(loginUrl);
}
private void webBrowser_Navigated(object sender, NavigationEventArgs e)
{
var fc = new FacebookClient();
FacebookOAuthResult fr;
// Check the returned url
if (fc.TryParseOAuthCallbackUrl(e.Uri, out fr))
{
// check if authentication is success or not
if (fr.IsSuccess)
{
getUserName(out userName);
}
else
{
var errorDes = fr.ErrorDescription;
var errorReason = fr.ErrorReason;
}
}
else
{
}
}
private void getUserName(out string name)
{
var fb = new FacebookClient(accessToken);
// Get the user details
dynamic result = fb.Get("me");
// Get the user name
name = result.name;
MessageBox.Show("Hai " + name + ",Welcome to my App");
}
}
我的問題是與FacebookOAuthResult
。
private void webBrowser_Navigated(object sender, NavigationEventArgs e)
{
var fc = new FacebookClient();
FacebookOAuthResult fr;
// Check the returned url
if (fc.TryParseOAuthCallbackUrl(e.Uri, out fr))
{
// check if authentication is success or not
if (fr.IsSuccess)
{
getUserName(out userName);
}
else
{
var errorDes = fr.ErrorDescription;
var errorReason = fr.ErrorReason;
}
}
else
{
}
}
我登錄後重定向到redirect_uri
。但fc.TryParseOAuthCallbackUrl(e.Uri, out fr)
失敗,雖然webbrowser重定向到認證成功頁面。
所以我無法獲得訪問令牌。我的代碼中存在什麼問題?
但即使在刪除offline_access之後,問題仍然存在。 – Naren 2013-04-26 08:57:17
