在WP7中使用facebook c＃sdk从Facebook登出 [英] Logging out from facebook using facebook c# sdk in WP7

问题描述

我想在我的Windows Phone应用程序中使用Facebook C＃sdk从Facebook实现注销

我的主要问题是我们如何使用WP7中的Facebook C＃SDK注销

我发现这篇文章在搜索

文章链接

他正在试图找到使用正则表达式注销url，但是在我的应用程序中没有工作

当我尝试浏览器浏览的事件进入无限循环

您可以在Windows Phone 7中分享与facebook注销相关的任何样品/帖子。

我想要注销应该发生在用户干预之后，点击在一个按钮上，他应该从Facebook上溜出去，下一次他应该看到登录页面

我也尝试过以下帖子/博客，但没有用。

更新

LogOutButtonCode

  FacebookClient _fbClient = new FacebookClient（fbaccess.AccessToken）; 
 var logoutParams = new Dictionary< string，object>（）; 
 logoutParams.Add（next，https://www.facebook.com/connect/login_success.html）; 
 //logoutParams.Add（，）
 
 var logoutUrl = _fbClient.GetLogoutUrl（logoutParams）; 
 BrowserControl.Navigated + = new EventHandler< System.Windows.Navigation.NavigationEventArgs>（BrowserControl_Navigated）; 
 
 BrowserControl.Navigate（new Uri（logoutUrl.AbsoluteUri））; 
  

导航事件代码

  if（e.Uri.AbsoluteUri ==https://www.facebook.com/connect/login_success.html）
 {
 
 
 NavigationService.Navigate（new Uri（/ MainPage.xaml，UriKind.Relative））; 
} 
  

e.Uri.AbsoluteUri返回 https：// www.facebook.com/home.php

注销URL我从服务器得到 https：// www .facebook.com / logout.php？next = https：//www.facebook.com/connect/login_success.html

解决方案

使用 FacebookClient.Logout 生成注销网址。

这是代码段来自 winforms示例，这将在wp7中进行一些修改。

  private void btnLogout_Click（object sender，EventArgs e）
 {
 var fb = new FacebookClient（）; 
 
 var logoutUrl = fb.GetLogoutUrl（new 
 {
 next =https://www.facebook.com/connect/login_success.html，
 access_token = _accessToken 
}）; 
 var webBrowser = new WebBrowser（）; 
 webBrowser.Navigated + =（o，args）=> 
 {
 if（args.Url.AbsoluteUri ==https://www.facebook.com/connect/login_success.html）
关闭（）; 
}; 
 
 webBrowser.Navigate（logoutUrl.AbsoluteUri）; 
} 
  

确保在登录时保存访问令牌，因为它需要登出。

I want to implement logout from facebook using facebook C# sdk in my windows phone app

My primary question is how do we logout using Facebook C# SDK in WP7

I found this article in search

Article link

there he is trying to find the logout url using regex, but that did not working in my app

when i try that the browser navigated event is going into infinite loop

you can share any samples/posts related to facebook logout in windows phone 7.

I want logout should happen with out user intervention, after he clicks on a button he should looged out from facebook and from next time he should see the login page

I tried following posts/blogs also but no use.

LINK 2 this giving error while splitting the accesstoken

UPDATE

LogOutButtonCode

 FacebookClient _fbClient = new FacebookClient(fbaccess.AccessToken);
        var logoutParams = new Dictionary<string, object>();
        logoutParams.Add("next", "https://www.facebook.com/connect/login_success.html");
        //logoutParams.Add("",)

        var logoutUrl = _fbClient.GetLogoutUrl(logoutParams);
        BrowserControl.Navigated += new EventHandler<System.Windows.Navigation.NavigationEventArgs>(BrowserControl_Navigated);

        BrowserControl.Navigate(new Uri(logoutUrl.AbsoluteUri));

Navigated Event CODE

if (e.Uri.AbsoluteUri == "https://www.facebook.com/connect/login_success.html")
        {


            NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative));
        }

e.Uri.AbsoluteUri returns https://www.facebook.com/home.php

Logout URL i am getting from the server https://www.facebook.com/logout.php?next=https://www.facebook.com/connect/login_success.html

解决方案

Use FacebookClient.Logout to generate the logout url.

This is the snippet from winforms sample which will work in wp7 with some modifications.

    private void btnLogout_Click(object sender, EventArgs e)
    {
        var fb = new FacebookClient();

        var logoutUrl = fb.GetLogoutUrl(new
                                            {
                                                next = "https://www.facebook.com/connect/login_success.html",
                                                access_token = _accessToken
                                            });
        var webBrowser = new WebBrowser();
        webBrowser.Navigated += (o, args) =>
                                    {
                                        if (args.Url.AbsoluteUri == "https://www.facebook.com/connect/login_success.html")
                                            Close();
                                    };

        webBrowser.Navigate(logoutUrl.AbsoluteUri);
    }

Make sure to persist the access token somewhere when you login as it is required to logout.
