C# ASP.NET标识Owin密码签名同步方法有时不起作用

当我尝试使用PasswordSignInAsync方法登录时，有时即使用户信息正确，它也会返回失败我按下登录按钮等待结果，如果不起作用，我再次按下，以此类推。它通常在第三次尝试时起作用。我们正在v2.2.1中使用Microsoft.AspNet.Identity.Owin。这是我们的代码：

    // POST: /Account/Login
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        // This doesn't count login failures towards account lockout
        // To enable password failures to trigger account lockout, change to shouldLockout: true
        var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToLocal(returnUrl);
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            case SignInStatus.Failure:
            default:
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
        }
    }

@M-Aktas。你能发布你的OWIN配置吗？我过去用身份编码。我记得，它使用http 302状态代码重定向。因此，多次单击登录按钮可能会干扰OWIN过程，您将收到上面描述的此类网站行为。@ywk5o您好，我发布了我的OWIN配置。你能再检查一下吗？我的英语不是很好，所以我想我说错了。在得到结果之前，我不会重复按登录按钮。我要做的是，我按下一次登录按钮，然后等待结果为“无效登录尝试”，然后再次按下它，并等待结果。然后我再按一次，它就工作了。但有时它在第一时间起作用。@M-Aktas。尝试Fiddler捕获http/s流量
