我在Windows Phone上注销Facebook时遇到问题。我有要登录的代码,但无法注销。有人可以告诉我如何在Windows Phone上注销Facebook吗?
这是登录代码:
私人FacebookClient _asyncFbClient;
私有字符串_appID =“”;
私有字符串_appSecret =“”;
私有void StartFacebookLogin(对象发送者,RoutedEventArgs e)
{
string [] extendedPermissions = new [] {“ user_about_me”,“ publish_stream”,“ email”};
FacebookClient fb =新的FacebookClient();
var oauth =新的FacebookOAuthClient {AppId = _appID,AppSecret = _appSecret};
var logout = new FacebookUser();
var参数=新的Dictionary <字符串,对象>
{
{“ response_type”,“令牌”},
{“显示”,“触摸”}
};
如果(extendedPermissions!= null && extendedPermissions.Length> 0)
{
var scope = new StringBuilder();
scope.Append(string.Join(“,”,extendedPermissions));
参数[“ scope”] = scope.ToString();
}
var loginUrl = oauth.GetLoginUrl(parameters);
webBrowser.Navigated + =新的EventHandler (CheckForAuth);
webBrowser.Navigate(loginUrl);
}
私人无效CheckForAuth(对象发送者,System.Windows.Navigation.NavigationEventArgs e)
{
FacebookOAuthResult结果;
如果(FacebookOAuthResult.TryParse(e.Uri,超出结果))
{
如果(结果。成功)
{
IsolatedStorageSettings设置= IsolatedStorageSettings.ApplicationSettings;
MessageBox.Show(result.AccessToken);
访问= result.AccessToken;
如果(Settings.Contains(“ MyFacebookAccessToken1”))
设置[“ MyFacebookAccessToken1”] = result.AccessToken;
别的
Settings.Add(“ MyFacebookAccessToken1”,result.AccessToken);
Settings.Save();
_asyncFbClient =新的FacebookClient(result.AccessToken);
_asyncFbClient.GetCompleted + =新的EventHandler (_ asyncFbClient_GetCompleted);
_asyncFbClient.GetAsync(“ / me”);
}
}
}
这是注销代码:
HttpWebRequest request =(HttpWebRequest)WebRequest.Create(linkUrl);
request.Method =“ GET”;
request.BeginGetResponse(new AsyncCallback(LogoutResponse),request);
私有无效LogoutResponse(IAsyncResult结果)
{
字符串responseData =“”;
尝试
{
HttpWebRequest request = result.AsyncState as HttpWebRequest;
HttpWebResponse response = request.EndGetResponse(result)as HttpWebResponse;
if(响应!= null && response.StatusCode == HttpStatusCode.OK)
{
流stream = response.GetResponseStream();
StreamReader reader =新的StreamReader(stream);
responseData = reader.ReadToEnd();
// responseData = true
}
}
抓住(前例外)
{
Dispatcher.BeginInvoke(()=> {MessageBox.Show(ex.Message);});
}
}
我尝试使用Facebook的注销API并获得成功的结果,但是下次我打开Web浏览器时,它已经自动再次登录到Facebook。如何注销? 
我尝试了很多技巧来使其工作……然后Facebook终于用一个很好的答案更新了他们的文档:
登出
您可以通过将用户定向到来退出其Facebook会话
以下网址:
https://www.facebook.com/logout.php?next=YOUR_URL&access_token=ACCESS_TOKEN
YOUR_URL必须是您网站域中的网址,如
开发人员应用程序。
从http://developers.facebook.com/docs/authentication/
|
没有FB注销,它已被删除。
最好的选择是忘记您的凭据。
|
Facebook PHP SDK使用如下功能:
公共函数getLogoutUrl($ params = array()){
返回$ this-> getUrl(
'万维网',
'logout.php',
array_merge(array(
'next'=> $ this-> getCurrentUrl(),
'access_token'=> $ this-> getAccessToken(),
),$ params)
);
}
它将创建如下网址:https://www.facebook.com/logout.php?next = {YOUR_ENCODED_URL}&access_token = {YOUR_ACCESS_TOKEN}
我相信编码的URL必须归access_token所属的应用程序所有。
如果您正确找到该URL,它将可以正常工作(仅针对我的一个应用程序尝试过)。
我不确定100%是否可以在Windows Phone上使用,但可以尝试一下。
