Google 身份验证在一段时间后停止工作答案

【问题标题】：Google Authentication stops working after some timeGoogle 身份验证在一段时间后停止工作
【发布时间】：2015-10-27 10:22:04
【问题描述】：

我们在这里遇到了一个奇怪的问题。我们有 asp.net 应用程序，允许用户使用谷歌唱歌。在本地一切正常，但是当我们将应用程序部署到生产环境并且用户尝试使用 google 登录时，它只是将他们重定向回登录页面。

现在奇怪的事情来了。部署后，当我们通过添加空格来修改 web.config 文件时，它开始工作一段时间，允许用户使用 google 登录。但经过一段时间后，它再次停止工作。

因此，如果我们再次修改 web.config，它会再次工作一段时间。

有人遇到过这样的问题吗？自过去 2 天以来，我一直在拉头发，但无法摆脱这个问题。请提出任何有用的建议。

【问题讨论】：

“某段时间”和“某段时间”分别是多少？
听起来有些东西被缓存了。当 web.config 更改时，应用程序池会被回收并清除缓存，一切都会重新开始工作。几年前我见过这样的事情，但不记得做了什么来解决它……服务器的事件查看器中是否显示任何错误或警告？
@LasseV.Karlsen 这可能工作 4-5 小时然后停止。
@user1666620 是的，你是对的。我们还知道，当 web.config 更新时，应用程序池会重新启动。但仍然无法弄清楚是什么导致了这个问题。
@SachinTrivedi 在失败时是否有任何错误或警告或信息消息记录在应用程序或事件查看器中？

【解决方案1】：

我设法通过设置虚拟会话值解决了这个问题。

[AllowAnonymous]
public ActionResult Login(string returnUrl)
{
    Session["dummy"] = "dummy"; // Create ASP.NET_SessionId cookie

    return View();
}
