c# - 为什么 signinmanager.passwordsigninasync 方法在 MVC5 中一直返回失败

Question

这是我的登录方法:

[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);
   }
}

这是我的授权过滤器:

protected override bool AuthorizeCore(HttpContextBase httpContext)
{
    var userEmailId = httpContext.Session["userName"];
    bool authorize = false;
    foreach (var role in allowedroles)
    {
        /* getting user form current context */
        var user = context.employees.Where(m => m.emailId == userEmailId  && m.Role == role);
        if (user.Count() > 0)
        {
            authorize = true; /* return true if Entity has current user(active) with specific role */
        }
    }
    return authorize;
}

这是我的操作方法:

[AuthAttribute]
[CustomAuthorize("Admin", "SuperAdmin")]
public ActionResult GetEmployeeList(string sortOrder, string currentFilter, string searchString, int? page)
{
    return View(db.GetListviewData().ToList());
}

我尝试使用授权过滤器从数据库中检查用户角色，但是当我尝试登录我的应用程序时，SignInManager.PasswordSignInAsync 方法每次都返回失败。

请帮助我，在此先感谢

我有同样的问题，但我意识到它只发生在用户更改他们的电子邮件之后(显然 UserName 不再等于 Email)。

看一下 PasswordSignInAsync 的签名，第一个参数是 UserName，但 Visual Studio 项目模板中的默认代码具有你我都拥有的 Email。

改变:

var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);

收件人:

var result = await SignInManager.PasswordSignInAsync(user.UserName, model.Password, model.RememberMe, shouldLockout: false);
