从 .NET 8 升级到 .NET 9 后，电子邮件确认不起作用

Question

用户注册时我有这样的代码：

var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
var callbackUrl = Url.Action("confirmemail", "home", new { userId = user.Id, code }, HttpContext.Request.Scheme);

// This code in here it is working
var result2 = await _userManager.ConfirmEmailAsync(user, code);

但是当我复制

callbackUrl

并从浏览器调用时，它无法确认用户。

var user = await _userManager.FindByIdAsync(userId);

if (user == null)
    return View("Error");

var result = await _userManager.ConfirmEmailAsync(user, code);

从 .NET 8 升级到 .NET 9 后有人遇到过这个问题吗？

Answer 1

我注意到，我们需要在发送电子邮件之前对代码进行 UrlEncode

var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
var encodedCode = HttpUtility.UrlEncode(code);
var callbackUrl = Url.Action("confirmemail", "home", new { userId = user.Id, code = encodedCode }, HttpContext.Request.Scheme);
