基于登录信息的C#Cookies

我在一个web应用程序上有两个登录控件，一个是默认的，另一个是默认的（命名约定将在我工作后更新）

我所做的是在每个登录名上设置一个cookie，该cookie将从login controls authenticate方法发送一个connectionstring名称。它将一个硬编码的字符串发送到名为Authenticate Users的基类。全班同学正在做以下工作

public class AuthenticatedUser : System.Web.UI.Page
{
public static string ConnectionString
{
    get
    {
        HttpCookie myCookie = HttpContext.Current.Request.Cookies["connectionString"];
        return GetConnectionStringFromName(myCookie);
    }
    set
    {
        HttpCookie oldCookie = HttpContext.Current.Request.Cookies["connectionString"];
        oldCookie.Expires = DateTime.Now.AddDays(-1);
        HttpCookie cookie = new HttpCookie("connectionString");
        cookie.Value = value;
        cookie.Expires = DateTime.Now.AddYears(100);
        HttpContext.Current.Request.Cookies.Add(cookie);
        string val = cookie.Value;
    }
}

private static string GetConnectionStringFromName(HttpCookie myCookie)
{
    string connectionStringName = myCookie.Value;
    return ConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString;
}

}

我在字符串“database1”和“database2”中搜索，这取决于它们使用的登录控件。当我调试代码时，connectionstring正在设置所有cookie信息，并且“database2”的一切都很好。然而，每次我使用与“database1”关联的表单登录时，它都会设置cookie，但调用get时，它仍然引用“database2”

这是因为cookie的名称相同，并且不会相互覆盖或更新自身，还是因为我的代码有问题

编辑——它仍然不能从上下文中删除cookie，当我运行“database1”时，它仍然会给我“database2”

最终编辑它的作品…这里是工作代码，如果有人感兴趣

public static string ConnectionString
{
    get
    {
        HttpCookie myCookie = HttpContext.Current.Request.Cookies["connectionString"];
        return GetConnectionStringFromName(myCookie);
    }
    set
    {
        if (HttpContext.Current.Request.Cookies["connectionString"] != null)
        {
            ExpireCookies(HttpContext.Current);
        }
        var allCookies = HttpContext.Current.Request.Cookies.AllKeys;
        HttpCookie cookie = new HttpCookie("connectionString");
        cookie.Value = value;
        cookie.Expires = DateTime.Now.AddYears(100);
        HttpContext.Current.Request.Cookies.Add(cookie);
        string val = cookie.Value;
    }
}

private static string GetConnectionStringFromName(HttpCookie myCookie)
{
    string connectionStringName = myCookie.Value;
    return ConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString;
}

private static void ExpireCookies(HttpContext current)
{
    var allCookies = current.Request.Cookies.AllKeys;
    foreach (var cook in allCookies.Select(c => current.Response.Cookies[c]).Where(cook => cook != null))
    {
        cook.Value = "";
        cook.Expires = DateTime.Now.AddDays(-1);
        current.Request.Cookies.Remove(cook.Name);
        cook.Name = "";
    }
}

您需要部分代码（使cookie过期）。但您还需要从上下文中删除，请尝试以下操作：

private static void ExpireCookies(HttpContext current)
    {
        var allCookies = current.Request.Cookies.AllKeys;

        foreach (var cook in allCookies.Select(c => current.Response.Cookies[c]).Where(cook => cook != null))
        {
            cook.Value = "";
            cook.Expires = DateTime.Now.AddDays(-1);
            current.Response.Cookies.Remove(cook.Name);
        }

    }
