asp.net-mvc-3 – 超时在ASP.Net MVC FormsAuthentication中不起

后来我发现这张票已经过期,但我没有注销(也是,所以我也想解决)！我看到你的问题没有得到回答,所以当我解决问题半天的时候,我保持开放.以下是我想出的,似乎是工作.

我的答案是基于这个答案. https://stackoverflow.com/a/454639/511438由用户ScottS

这是在我的ASP.NET MVC 3项目.

这是我的登录代码.未显示,自定义用户认证逻辑之前.这只是设置初始票.

public class FormsAuthenticationService：IFormsAuthentication

public void SignIn(string userName,bool createPersistentCookie,string role)
{
    FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
            1,// version
            userName,// user name
            DateTime.Now,// created
            DateTime.Now.Add(FormsAuthentication.Timeout),// expires
            false,// rememberMe?
            role                        // can be used to store roles
            );

    string encryptedTicket = FormsAuthentication.Encrypt(authTicket);

    HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName,encryptedTicket);
    HttpContext.Current.Response.Cookies.Add(authCookie);
}

在同一个类中,但是从global.asax访问的静态方法

//-- this is based on https://stackoverflow.com/questions/454616/asp-net-cookies-authentication-and-session-timeouts
internal static FormsAuthenticationTicket RefreshLoginCookie(bool retainCurrentExpiry)
{
    HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
    if (authCookie == null || authCookie.Value == null)
        return null;

    FormsAuthenticationTicket oldTicket = FormsAuthentication.Decrypt(authCookie.Value);

    DateTime expiryDate = (retainCurrentExpiry ? oldTicket.Expiration : DateTime.Now.Add(FormsAuthentication.Timeout));
    HttpContext.Current.Response.Cookies.Remove(FormsAuthentication.FormsCookieName);

    var newTicket = new FormsAuthenticationTicket(oldTicket.Version,oldTicket.Name,oldTicket.IssueDate,expiryDate,oldTicket.IsPersistent,oldTicket.UserData,oldTicket.CookiePath);

    HttpCookie newAuthCookie = new HttpCookie(FormsAuthentication.FormsCookieName,FormsAuthentication.Encrypt(newTicket));
    HttpContext.Current.Response.Cookies.Add(newAuthCookie);

    return newTicket;

}

Global.asax中

我的自定义是ajax请求不刷新表单身份验证票证.所以如果你坐在那里的超时时间,一个ajax请求将会注销你.更改,如果你想要ajax请求保持机票活着(解决我的JavaScript cookie问题,而不是你的注销不活动问题).
*(提示,如果您注销,然后登录,但再次回到登录页面,第一次登录也没有在querystring中指定一个returnUrl). *

protected virtual void Application_AuthenticateRequest(Object sender,EventArgs e)
{
    HttpCookie authCookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName];
    if (authCookie == null || authCookie.Value == "")
    {
        return;
    }

    bool isAjax = new HttpRequestWrapper(System.Web.HttpContext.Current.Request).IsAjaxRequest();

    FormsAuthenticationTicket authTicket;
    try
    {
        //-- THIS IS WHAT YOU WANT
        authTicket = FormsAuthenticationService.RefreshLoginCookie(isAjax);
    }
    catch
    {
        return;
    }

    string[] roles = authTicket.UserData.Split(';');
    if (Context.User != null) Context.User = new GenericPrincipal(Context.User.Identity,roles);

}

Web.config文件
这里是我设置会话超时和机票超时的部分

<configuration>
    <system.web>
        <sessionState mode="InProc" timeout="60" />
        <authentication mode="Forms">
            <forms loginUrl="~/Account/Login" timeout="60" name="ProviderMvcSession" cookieless="UseCookies" />
        </authentication>
