使用 UserManager 更改用户的电子邮件

Using UserManager to change the email of a user

我正在尝试实现一项更改用户电子邮件的功能。 Asp 默认情况下,网络核心身份允许用户更改电子邮件,但需要确认 link。我想知道是否可以不使用确认 link 而只是编辑函数以使用新电子邮件更新用户的电子邮件。提前致谢

我试过

 await _userManager.ChangeEmailAsync(user, Input.NewEmail, code);

var changingser = _userManager.Users.First(u => u.Email.Equals(email));
changingser.Email = Input.NewEmail;

这似乎不起作用

Email.cshtml: 更改邮箱功能

    public async Task<IActionResult> OnPostChangeEmailAsync()
    {
        var user = await _userManager.GetUserAsync(User);
        if (user == null)
        {
            return NotFound($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
        }

        if (!ModelState.IsValid)
        {
            await LoadAsync(user);
            return Page();
        }

        var email = await _userManager.GetEmailAsync(user);
        if (Input.NewEmail != email)
        {
            var userId = await _userManager.GetUserIdAsync(user);
            var code = await _userManager.GenerateChangeEmailTokenAsync(user, Input.NewEmail);
            code = WebEncoders.Base64UrlEncode(Encoding.UTF8.GetBytes(code));

            await _userManager.ChangeEmailAsync(user, Input.NewEmail, code);

/*                var callbackUrl = Url.Page(
                    "/Account/ConfirmEmailChange",
                    pageHandler: null,
                    values: new { userId = userId, email = Input.NewEmail, code = code },
                    protocol: Request.Scheme);*/

                //await _emailSender.SendEmailAsync(
                //    Input.NewEmail,
                //    "Confirm your email",
                //    $"Please confirm your account by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");

            StatusMessage = "Email has been changed";
            return RedirectToPage();
        }

        StatusMessage = "Your email is unchanged.";
        return RedirectToPage();
    }

编辑:令牌无效?

是的,你可以。

使用 SetEmailAsync 查看 user 电子邮件。
这仍然需要电子邮件是 'confirmed' 所以生成一个令牌,然后立即确认新的电子邮件地址。

类似于:

await _userManager.SetEmailAsync(user, Input.NewEmail);

var token = await _userManager.GenerateEmailConfirmationTokenAsync(existingUser);

await _userManager.ConfirmEmailAsync(existingUser, token);
