如何防止“您已经授权了此应用" Facebook上的消息在WP8.1中连接? [英] How to prevent "You have already authorized this app" message on Facebook connect in WP8.1?

问题描述

我正在学习在WP8.1中集成Facebook登录.我的问题是，每次我按下连接按钮时，我都需要 facebook询问我的身份证明，但是它没有这样做，它会记住上一次登录并提示您已经授权了my_app_name".我该如何解决?无论如何，我可以阻止Facebook记住上一次登录吗? 我遵循了这教程，仅供参考

任何帮助将不胜感激.谢谢.

解决方案

我想出了解决方案.当用户点击连接到Facebook"按钮时，我使用WebAuthenticationBroker.AuthenticateSilentlyAsync静默调用注销uri.在打开Facebook连接对话框之前，这不会打开UI线程并注销以前登录的用户.

因此，基本上，每当用户尝试将我的应用程序连接到facebook时，它都会在显示连接对话框之前注销先前登录的用户.

I'm learning to integrate facebook login in WP8.1. My problem is that I need facebook to ask me for my credentials every time I press the connect button but it does not do that, it remembers the last log in and prompts "You have already authorized my_app_name". How do I go around this? Is there anyway I can prevent facebook to remember the last login? I've followed THIS tutorial, just fyi

Any help would be really appreciated. Thanks.

解决方案

I figured out the solution to this. When the user taps on the connect to facebook button, I silently call the logout uri using WebAuthenticationBroker.AuthenticateSilentlyAsync. This does not open the UI thread and logs out the previously logged in user before opening the facebook connect dialog.

So essentially every time a user tries to connect my application to facebook, it logs out the previous logged in user before presenting the connect dialog.
