当我的网站负载很重时，我的网站会产生奇怪的影响。

我随机获取其他用户设置的属性。我有自己的配置文件系统实现，所以我想我不能责怪配置文件系统本身。

我只需要一个点来开始调试。我猜有一个 cookie 值映射到某处的 Profile 条目。有没有机会看看这个映射是如何工作的？

这是我的个人资料提供者：

这就是我在控制器中使用它的方式：

    public ActionResult AddTyreToCart(CartViewModel model)
    {

        string profile = Request.IsAuthenticated ? Request.AnonymousID : User.Identity.Name;

    }

我想调试：提供不同cookie的2个用户如何获得相同的profileid？

编辑

这是 getuniqueid 的代码

public int GetUniqueID(string userName, bool isAuthenticated, bool ignoreAuthenticationType, string appName)
{

  SqlParameter[] parms = {
            new SqlParameter("@Username", SqlDbType.VarChar, 256),
            new SqlParameter("@ApplicationName", SqlDbType.VarChar, 256)};
  parms[0].Value = userName;
  parms[1].Value = appName;

  if (!ignoreAuthenticationType)
  {
    Array.Resize(ref parms, parms.Length + 1);
    parms[2] = new SqlParameter("@IsAnonymous", SqlDbType.Bit) { Value = !isAuthenticated };
  }

  int userID;

  object retVal = null;
  retVal = SqlHelper.ExecuteScalar(ConfigurationManager.ConnectionStrings["SQLOrderB2CConnString"].ConnectionString, CommandType.StoredProcedure, "getProfileUniqueID", parms);

  if (retVal == null)
    userID = CreateProfileForUser(userName, isAuthenticated, appName);
  else
    userID = Convert.ToInt32(retVal);
  return userID;
}

这是SP：

CREATE  PROCEDURE [dbo].[getProfileUniqueID]

@Username VarChar( 256),
@ApplicationName VarChar( 256),
@IsAnonymous bit = null
AS
BEGIN

    SET NOCOUNT ON;
/*

created 
08.07.2009  mf

Retrive unique id for current user

*/
SELECT UniqueID FROM dbo.Profiles WHERE Username = @Username 
AND ApplicationName = @ApplicationName
AND IsAnonymous = @IsAnonymous or @IsAnonymous = null

END

我没有深入研究这一点，但有一件事确实让我眼前一亮。

在您的 where 子句中更改

@IsAnonymous = null

至

@IsAnonymous IS NULL

当@IsAnonymous 为空时，你想发生什么？您可能需要在 where 子句中添加一些括号。

SELECT UniqueID FROM dbo.Profiles 
WHERE Username = @Username 
    AND ApplicationName = @ApplicationName
    AND (IsAnonymous = @IsAnonymous OR @IsAnonymous IS NULL)

你们两个收到相同个人资料数据的用户吗？如果是这样，从那里开始。我会先通过存储过程运行它们。这将是容易和快速的。

这是一种非常难以解决的问题。我们在 ASP.NET 应用程序（不是 MVC）中遇到了类似的问题。我建议您可以先设置一个单独的 cookie 来识别用户，完全绕过 ASP.NET 配置文件系统。然后，您可以检查该 cookie 中的身份是否与配置文件中的身份相匹配。如果没有，那么您可以 1) 注销用户，以便至少他们无法访问其他人的数据，以及 2) 收集一些诊断信息 - 完整的 HTTP 请求详细信息将是一个开始。如果这没有建立任何类型的模式，您可以开始记录用户的所有 HTTP 请求，以查看他们的请求历史记录中是否有模式可以帮助您重现问题。

在我们的案例中，问题最终变成了一种愚蠢的本土缓存机制。应用程序将尝试在 ASP.NET 中缓存静态文件（例如图像），并且 cookie 与它们一起缓存。在重负载下，用户有时会使用其他用户的 cookie 加载图像并假设其他用户的身份。您的情况可能完全不同，但这可能会给您一些关于要寻找的事物类型的线索。

每当发生此类问题时...我已经看到以下原因...

  1. 缓存
  2. 静态变量

您可以尝试在没有静态变量的情况下编写此代码并检查问题是否解决？

问候， 拉胡尔

给定的来源似乎没问题，但如果没有所有相应的源代码（例如，B2CShop.DAL.UserRepository 类的所有使用方法），甚至可能是数据库方案，我就无法做出深刻的陈述。

首先是检查数据库中的数据是否已损坏，也就是说，某些用户可能实际上拥有相同的唯一 ID 或相同的用户名/应用程序/同名组合。如果 uniqueid 是主键，则可以排除此项。
