UserManager：如何检查是否使用了 GenerateChangeEmailTokenAsync() 生成的代码

Question

我使用 UserManager 的 GenerateChangeEmailTokenAsync() 生成验证码并将其发送到新邮箱。我想检查该代码是否已在未经身份验证的上下文中使用，如果新电子邮件已经过验证，则向用户显示一条消息：“您的新电子邮件地址已经过验证。请登录”。

UserManager 中是否有方法可以完成此操作？

恐怕userManager中没有方法可以达到你的要求，但我想你可以自己传递这个成功信息。可以参考这段代码：

            //I use this code to get the currently logged in user
            var user = _userManager.GetUserAsync(User).Result;

            var result = await _userManager.ChangeEmailAsync(user, newEmail, token);

            if (result.Succeeded)
            {
                TempData["Message"] = "Your new email address has already been verified. Please log in";
                return RedirectToAction("ChangeEmail", "Test");
            }
            else
            {
                TempData["Message"] = "Email change failed";
                return RedirectToAction("ChangeEmail", "Test");
            }

Test/ChangeEmail

        [HttpGet]
        public IActionResult ChangeEmail()
        {
          //use ViewBag to pass data from controller to view
            ViewBag.Message = TempData["Message"];
            return View();
        }

查看

//.....
<h1>@ViewBag.Message</h1>

如果更改邮箱成功，会在视图中显示消息
