如何清除 Silverlight/Windows Phone 7 中的导航历史记录? [英] How do I clear navigation history in Silverlight/Windows Phone 7?

问题描述

我正在制作一个具有登录/注销语义的 Windows Phone 7 应用程序(对网络应用程序进行身份验证).当用户注销时，我导航回登录屏幕并忘记会话身份验证.

I'm making a Windows Phone 7 app that has login/logout semantics (authenticating to a web app). When the user logs out I navigate back to the login screen and forget the session authentication.

这样做时，我还想清除导航历史记录，这样就无法返回期望它们已经通过身份验证的页面.

When doing so I'd also like to clear the navigation history so that can't go back to a page that expects them to be already authenticated.

看不到如何使用 NavigationService 来做这件事，我想知道是否有办法做到这一点.

Can't see how to do it with NavigationService and am wondering if there is a way to do this.

推荐答案

这里有几件事要看.首先，我建议您熟悉此处提供的指南.

There are a few things to look at here. First is I recommend familiarising with the guidance offered here.

介绍地点"的概念 - Peter Torr 的博客

重定向初始导航 - Peter Torr 的博客(抱歉，暂时关闭了)

如果您能够在此指导下工作，那是最佳途径.有处理登录屏幕的具体建议.

If you're able to work within this guidance that is the best path. There is specific advice for dealing with login screens.

如果您被迫提供主页按钮功能.请注意如何应用这一点，因为验证者会因为应用程序在导航方面的表现出乎意料而退缩.我觉得如果这个功能在主页按钮后面，你在惊喜部门应该没问题.随着时间的推移，我们将看到认证的情况.可以说是注销"场景同样适用.

If you are compelled to offer a home button feature. Be careful how you apply this, as certifiers are knocking apps back for behaving in unexpected ways with respect to navigation. I feel if this function is behind a home button you should be ok in the surprise department. How this stands over time with certification we will see. Arguably a "logout" scenario applies equally.
