【问题描述】：

我想在我的应用程序中更新密码。这是我的登录 IAction

控制器

    [HttpGet]
    [AllowAnonymous]
    public async Task<IActionResult> Login(string returnUrl = null)
    {
        // Clear the existing external cookie to ensure a clean login process
        await HttpContext.SignOutAsync(IdentityConstants.ExternalScheme);

        ViewData["ReturnUrl"] = returnUrl;
        return View();
    }
[HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
    {
        if (ModelState.IsValid)
        {
            var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);

            if (result.Succeeded)
            {

                _logger.LogInformation("User logged in.");
                return RedirectToLocal(returnUrl);
            }
            if (result.RequiresTwoFactor)
            {
                return RedirectToAction(nameof(LoginWith2fa), new { returnUrl, model.RememberMe });
            }
            if (result.IsLockedOut)
            {
                _logger.LogWarning("User account locked out.");
                return RedirectToAction(nameof(Lockout));
            }

            else
            {
                ModelState.AddModelError(string.Empty, "Invalid login attempt.");
                return View(model);
            }
        }
        return View(model);
    }

现在我当前的电子邮件和密码是

电子邮件：john@gmail.com

密码：john@gmail.com123

我想将密码 john@gmail.com123 更新为 john@gmail.com677

【问题讨论】：

ASP.Net Identity 有一个 UserManager。
你能告诉我如何更新当前密码吗？

【解决方案1】：

如果您使用来自模板（个人用户帐户）的 asp.net core 2.0 身份，您将能够在ChangePassword 视图中更新您的密码，网址为https://localhost:xxxx/Manage/ChangePassword。

使用await _userManager.ChangePasswordAsync(user, model.OldPassword, model.NewPassword);更新密码。

您将在ManageController.cs 中了解如何完全实现这一目标。

[HttpGet]
    public async Task<IActionResult> ChangePassword()
    {
        var user = await _userManager.GetUserAsync(User);
        if (user == null)
        {
            throw new ApplicationException($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
        }

        var hasPassword = await _userManager.HasPasswordAsync(user);
        if (!hasPassword)
        {
            return RedirectToAction(nameof(SetPassword));
        }

        var model = new ChangePasswordViewModel { StatusMessage = StatusMessage };
        return View(model);
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> ChangePassword(ChangePasswordViewModel model)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        var user = await _userManager.GetUserAsync(User);
        if (user == null)
        {
            throw new ApplicationException($"Unable to load user with ID '{_userManager.GetUserId(User)}'.");
        }

        var changePasswordResult = await _userManager.ChangePasswordAsync(user, model.OldPassword, model.NewPassword);
        if (!changePasswordResult.Succeeded)
        {
            AddErrors(changePasswordResult);
            return View(model);
        }

        await _signInManager.SignInAsync(user, isPersistent: false);
        _logger.LogInformation("User changed their password successfully.");
        StatusMessage = "Your password has been changed.";

        return RedirectToAction(nameof(ChangePassword));
    }
