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(对Web应用程序进行身份验证)的Windows Phone 7应用程序.当用户注销时，我导航回到登录屏幕，而忘记了会话身份验证.
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，以便无法返回到期望它们已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.
无法看到如何使用NavigationService来执行此操作，并且想知道是否有一种方法可以执行此操作.
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导.
There are a few things to look at here. First is I recommend familiarising with the guidance offered here.
如果您能够按照此指南进行操作，那将是最佳途径.对于处理登录屏幕有一些具体建议.
If you're able to work within this guidance that is the best path. There is specific advice for dealing with login screens.
如果您不得不提供主页按钮功能.请谨慎使用此方法，因为验证者会将应用程序以导航方面的意外行为拒之门外.我觉得如果此功能位于主页按钮后面，那么您应该在惊喜部门内还可以.随着时间的流逝，这将如何证明我们将获得认证.可以说，注销"方案同样适用.
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.
