1. 添加重设密码功能 添加忘记密码的链接和重置密码的视图。在忘记密码的视图中，用户输入他们的电子邮件地址，当他们单击按钮时，控制器将通过电子邮件发送重置密码链接。当用户单击链接时，他们将重定向到重置密码视图。以下是示例代码：

[HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task ForgotPassword(ForgotPasswordViewModel model) { if (ModelState.IsValid) { var user = await UserManager.FindByNameAsync(model.Email); if (user == null || !(await UserManager.IsEmailConfirmedAsync(user.Id))) { // Don't reveal that the user does not exist or is not confirmed return View("ForgotPasswordConfirmation"); }

    // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
    // Send an email with this link
    string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
    var callbackUrl = Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
    await UserManager.SendEmailAsync(user.Id, "Reset Password", "Please reset your password by clicking here: link");
    return View("ForgotPasswordConfirmation");
}

// If we got this far, something failed, redisplay form
return View(model);

}

[AllowAnonymous] public ActionResult ForgotPassword() { return View(); }

[AllowAnonymous] public ActionResult ForgotPasswordConfirmation() { return View(); }

[AllowAnonymous] public ActionResult ResetPassword(string code) { return code == null ? View("Error") : View(); }

[HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task ResetPassword(ResetPasswordViewModel model) { if (!ModelState.IsValid) { return View(model); } var user = await UserManager.FindByNameAsync(model.Email); if (user == null) { // Don't reveal that the user does not exist return RedirectToAction("ResetPasswordConfirmation", "Account"); } var result = await UserManager.ResetPasswordAsync
