C# 角度+；ASP.NET MVC4会话始终为空

我正在angular中开发一个SPA，它在nginx服务器中运行，在IIS服务器中运行的ASP.NET MVC4 web应用程序为angular应用程序提供一些API函数。一旦用户登录，一些数据就需要保存在httpsession中（假设我不想使用angular的会话存储）。但是会话总是返回null，即使我在成功登录后存储了一些数据。请看一些必要的代码

authservice.js

login: function (email, password) {
     var deferred = $q.defer();
     $http({
          url: global.API_URL + '/Auth/Login',
          method: 'POST',
                data: { email: email, password: encodeURIComponent(password)}
   }).then(function (response) {
       if (response.data.code == 0) {
          //If success go to home
});

    [ActionName("Login")]
    [HttpPost]
    public JsonResult Index(string email, string password)
    {
    CustResponse response = new CustResponse ();
    //Get the logged in user data
     User user = userService.GetUser(email);   

    //Get the hash 
    string hash = PasswordUtil.CreatePasswordHash(user.Salt, password);

    //Custom membership provider
    CustMembershipProvider provider = new CustMembershipProvider();
    bool isValid = provider.ValidateUser(email, hash); 

//Store the user token into the session
  System.Web.HttpContext.Current.Session["TOKEN"] = //Some token value;

    //if valid send response code 0
    response.code = 0;
    response.message = "Success";
    response.data = isValid ;

    return Json(response);
    }

 public class CustMembershipProvider : MembershipProvider
    {
        public override bool ValidateUser(string email, string hash)
        {
            bool isValid = false;
            using (var db = new AwmsContext())
            {
               User user = db.Users.SingleOrDefault(a => a.Email == email);
               if (user != null && user.PasswordHash != null &&            user.PasswordHash.Equals(hash))
              {
                  isValid = true;
               }
            }
            return isValid;
        }

AuthController.js

login: function (email, password) {
     var deferred = $q.defer();
     $http({
          url: global.API_URL + '/Auth/Login',
          method: 'POST',
                data: { email: email, password: encodeURIComponent(password)}
   }).then(function (response) {
       if (response.data.code == 0) {
          //If success go to home
});

    [ActionName("Login")]
    [HttpPost]
    public JsonResult Index(string email, string password)
    {
    CustResponse response = new CustResponse ();
    //Get the logged in user data
     User user = userService.GetUser(email);   

    //Get the hash 
    string hash = PasswordUtil.CreatePasswordHash(user.Salt, password);

    //Custom membership provider
    CustMembershipProvider provider = new CustMembershipProvider();
    bool isValid = provider.ValidateUser(email, hash); 

//Store the user token into the session
  System.Web.HttpContext.Current.Session["TOKEN"] = //Some token value;

    //if valid send response code 0
    response.code = 0;
    response.message = "Success";
    response.data = isValid ;

    return Json(response);
    }

 public class CustMembershipProvider : MembershipProvider
    {
        public override bool ValidateUser(string email, string hash)
        {
            bool isValid = false;
            using (var db = new AwmsContext())
            {
               User user = db.Users.SingleOrDefault(a => a.Email == email);
               if (user != null && user.PasswordHash != null &&            user.PasswordHash.Equals(hash))
              {
                  isValid = true;
               }
            }
            return isValid;
        }

当我在AuthController中时，我可以在会话对象中看到令牌被存储到会话中

 public JsonResult GetRoles()
        {
               String token = (String)System.Web.HttpContext.Current.Session["TOKEN"];
.....
}

AwmsMembershipProvider.cs

login: function (email, password) {
     var deferred = $q.defer();
     $http({
          url: global.API_URL + '/Auth/Login',
          method: 'POST',
                data: { email: email, password: encodeURIComponent(password)}
   }).then(function (response) {
       if (response.data.code == 0) {
          //If success go to home
});

    [ActionName("Login")]
    [HttpPost]
    public JsonResult Index(string email, string password)
    {
    CustResponse response = new CustResponse ();
    //Get the logged in user data
     User user = userService.GetUser(email);   

    //Get the hash 
    string hash = PasswordUtil.CreatePasswordHash(user.Salt, password);

    //Custom membership provider
    CustMembershipProvider provider = new CustMembershipProvider();
    bool isValid = provider.ValidateUser(email, hash); 

//Store the user token into the session
  System.Web.HttpContext.Current.Session["TOKEN"] = //Some token value;

    //if valid send response code 0
    response.code = 0;
    response.message = "Success";
    response.data = isValid ;

    return Json(response);
    }

 public class CustMembershipProvider : MembershipProvider
    {
        public override bool ValidateUser(string email, string hash)
        {
            bool isValid = false;
            using (var db = new AwmsContext())
            {
               User user = db.Users.SingleOrDefault(a => a.Email == email);
               if (user != null && user.PasswordHash != null &&            user.PasswordHash.Equals(hash))
              {
                  isValid = true;
               }
            }
            return isValid;
        }
