在同一台服务器上的网站之间读取表单身份验

我在同一台Windows服务器上托管了两个网站 .

1）Asp.net Web应用程序框架4.0（abc.com/site1）

2）MVC应用程序框架4.5.2（abc.com/site2）

现在我想在这些站点之间实现SSO方法 . 即当用户登录到asp.net应用程序时，它会被重定向到MVC应用程序，然后我将检查表单auth cookie .

但我有问题阅读形式auth cookie .

• 当用户登录到asp.net应用程序时，我使用下面的代码进行表单身份验证

FormsAuthentication.SetAuthCookie(txtUserName.Text.Trim(), false);
        FormsAuthenticationTicket ticket1 =
            new FormsAuthenticationTicket(
                 1,                                   // version
                 txtUserName.Text.Trim(),   // get username  from the form
                 DateTime.Now,                        // issue time is now
                 DateTime.Now.AddMinutes(30),         // expires in 30 minutes
                 false,     // cookie is not persistent
                 ""                              // role assignment is stored
            // in userData
                 );
        HttpCookie cookie1 = new HttpCookie(
          FormsAuthentication.FormsCookieName,
          FormsAuthentication.Encrypt(ticket1));
        cookie1.Domain = FormsAuthentication.CookieDomain;
        Response.Cookies.Add(cookie1);

和web.config代码如下

<authentication mode="Forms">
      <forms name="Form.AUTH" loginUrl="~/Home.aspx" protection="All" path="/" requireSSL="true" domain="abc.com" cookieless="UseCookies" />
    </authentication>
    <machineKey validationKey="4B616C4E8BE5E18C3A1650939E88F3B0ED1AFC692919D7937DA68BBC552F04027DCF8BD31125E5E69094E1A4BA96731067BB57F0D3C34B63B9B03123703CD01A" decryptionKey="EC095D7743D3368F22FB7F482D9F41AA911922EC753515BB"   validation="HMACSHA384"  compatibilityMode="Framework20SP2" />

现在为第二个应用程序（MVC）读取相同的cookie，Web.config更改如下

<machineKey validationKey="4B616C4E8BE5E18C3A1650939E88F3B0ED1AFC692919D7937DA68BBC552F04027DCF8BD31125E5E69094E1A4BA96731067BB57F0D3C34B63B9B03123703CD01A" decryptionKey="EC095D7743D3368F22FB7F482D9F41AA911922EC753515BB"   validation="HMACSHA384"  compatibilityMode="Framework20SP2" />

    <authentication mode="Forms">
      <forms loginUrl="account/" name="Form.AUTH" protection="All" path="/"  domain="abc.com" requireSSL="true" cookieless="UseCookies"></forms>
    </authentication>

并在MVC应用程序中读取相同的cookie，代码如下 . 我用Global.asax文件编写

protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
        {
            try
            {
                if (Request.IsAuthenticated)
                {
                    logClass.logger.Info("Request is authencated  -- If");
                }
                else
                {
                    logClass.logger.Info("Request is authencated   -- else");
                }
            }
            catch (Exception ex)
            {

                logClass.logger.Info("Request is authencated -- Error");
            }

            try
            {
                if (User.Identity.IsAuthenticated)
                {
                    logClass.logger.Info("User.Identity.IsAuthenticated -- If");
                }
                else
                {
                    logClass.logger.Info("User.Identity.IsAuthenticated -- else");
                }
            }
            catch (Exception ex)
            {

                logClass.logger.Info("User.Identity.IsAuthenticated -- Error");
            }


            HttpCookie authCookie = HttpContext.Current.Request.Cookies["Form.AUTH"];
            string[] myCookies = Request.Cookies.AllKeys;
            logClass.logger.Info(myCookies);
            logClass.logger.Info(FormsAuthentication.FormsCookieName);
            try
            {

                logClass.logger.Info(HttpContext.Current.Request.Cookies["Form.AUTH"].Value);
            }
            catch (Exception)
            {

                logClass.logger.Info("Error value");
            }
            if (authCookie != null)
            {
                logClass.logger.Info(authCookie.Value);
                FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                if (authTicket.UserData == "OAuth") return;
                CustomPrincipalSerializedModel serializeModel =
                  serializer.Deserialize<CustomPrincipalSerializedModel>(authTicket.UserData);
                CustomPrincipal newUser = new CustomPrincipal(authTicket.Name);
                //newUser.Id = serializeModel.Id;
                newUser.FirstName = serializeModel.FirstName;
                newUser.LastName = serializeModel.LastName;
                HttpContext.Current.User = newUser;
            }
        }

现在的问题是，当用户登录到asp.net Web应用程序用户进行身份验证并创建表单身份验证cookie但是当打开MVC应用程序时，您可以看到以下代码都不起作用

Request.IsAuthenticated  : false
User.Identity.IsAuthenticated   : false

 HttpCookie authCookie = HttpContext.Current.Request.Cookies["Form.AUTH"];  // its null
                string[] myCookies = Request.Cookies.AllKeys;
                logClass.logger.Info(myCookies);  // no Form.AUTH cookie in it
                logClass.logger.Info(FormsAuthentication.FormsCookieName);
