登录尝试无效.登录时身份asp mvc

本文关键字：登录 asp mvc 身份 无效 | 更新日期: 2023-09-27 18:12:23

我使用以下代码检查登录:

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
    if (!ModelState.IsValid)
    {
        return View(model);
    }
    var user = await UserManager.FindByEmailAsync(model.Email);
    if (user != null)
    {
        if (!await UserManager.IsEmailConfirmedAsync(user.Id))
        {
            ViewBag.errorMessage = "You must have a confirmed email to log on.";
            return View("Error");
        }
    }
    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);
    }
}

当我登录时显示这个错误:Invalid login attempt.但是电子邮件和密码已经存在。

代码:

var user = await UserManager.FindByEmailAsync(model.Email);

不是null，但是这个代码是Failure:

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

怎么了?如何解决这个问题?

如果您已经通过电子邮件找到了一个有效的用户，那么请使用找到的用户名登录。

//...
var user = await UserManager.FindByEmailAsync(model.Email);
if (user != null) {
    if (!await UserManager.IsEmailConfirmedAsync(user.Id)) {
        ViewBag.errorMessage = "You must have a confirmed email to log on.";
        return View("Error");
    }
}
var result = await SignInManager.PasswordSignInAsync(user.Username, model.Password, model.RememberMe, shouldLockout: false);
//...

在registrationConfirmation中放置处于开发阶段的user.emailconfirmed = true。当您迁移到生产环境时，请删除此代码。
