c# – 未使用OWIN承载令牌对用户登录进行身份验证

我面临的问题是,当我点击MVC应用程序中的“登录”按钮时,API正在生成令牌以及用户信息.但是我无法在视图中显示用户信息.

以下代码位于MVC App的AccountController中

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model)
{
   string token = Token.GetToken(Token.GRANT_TYPE,model.Email,model.Password,Token.CLIENT_ID,Token.CLIENT_SECRET);

  //token has the appropriate data if I debug it

   if (!string.IsNullOrEmpty(token))
       return RedirectToAction("Index","Home");

   return View(model);
}

然后在视图中我有

@if (Request.IsAuthenticated)
{
  <p>@User.Identity.GetUserName()</p> //this line is always blank
}

API看起来像这样

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{

        var allowedOrigin = context.OwinContext.Get<string>("as:clientAllowedOrigin");

        if (allowedOrigin == null) allowedOrigin = "*";

        context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin",new[] { allowedOrigin });

        using (AuthRepository _repo = new AuthRepository())
        {
            ApplicationUser user = await _repo.FindUser(context.UserName,context.Password);

            if (user == null)
            {
                context.SetError("invalid_grant","The user name or password is incorrect.");
                return;
            }
        }

        var identity = new ClaimsIdentity(context.Options.AuthenticationType);

        identity.AddClaim(new Claim(ClaimTypes.Name,context.UserName));
        identity.AddClaim(new Claim(ClaimTypes.Role,"user"));
        identity.AddClaim(new Claim("sub",context.UserName));

        var props = new AuthenticationProperties(new Dictionary<string,string>
            {
                {
                    "as:client_id",(context.ClientId == null) ? string.Empty : context.ClientId
                },{
                    "userName",context.UserName
                },{
                    "email",});

        var ticket = new AuthenticationTicket(identity,props);
        context.Validated(ticket);
}

有人能告诉我为什么请求没有被认证？我错过了什么
