ASP.NET Identity 3.0 上的 IIdentityMessageService 等价物是什么？

Question

在 ASP.NET Identity 2.X 上，我们可以通过 Microsoft.AspNet.Identity.Core 库中的 IIdentityMessageService 接口配置通知基础结构，该库未升级到版本 3.0。

在 ASP.NET Identity 3.0 上配置消息传递基础结构的做法是什么？

Answer 1

似乎没有更多的电子邮件服务插入到 Asp.Net Identity。您只需定义自己的界面。 ASP.NET 身份的作用是生成和验证电子邮件确认令牌和密码重置令牌。

public interface IEmailService
{
    Task SendAsync(string to, string subject, string body);
}

发送电子邮件验证帐户

private async Task SendEmailConfirmation(User user)
{
    string token = await this._userManager.GenerateEmailConfirmationTokenAsync(user);
    string callbackUrl = this._urlHelper.Action("EmailConfirmed", "Account", new ConfirmTokenViewModel(user.Id, token), protocol: this._contextAccessor.HttpContext.Request.Scheme);

    await this._emailService.SendAsync(to: user.Email,
            subject: "Confirm your account",
            body: "Please confirm your e-mail by clicking this link: <a href=\"" + callbackUrl + "\">link</a>");
}

OBS：this._urlHelper 是一个 IUrlHelper。它可以是属性 Controller.Url 或构造函数注入生成的新实例。

然后，确认电子邮件

[HttpGet]
[AllowAnonymous]
public async Task<IActionResult> EmailConfirmed(ConfirmTokenViewModel model)
{
    if (!this.ModelState.IsValid)
return View("Error");

    bool succeeded = await this._accountsManager.ConfirmEmail(model.UserId, model.Token);
    return succeeded ? View() : View("Error");
}

public async Task<bool> ConfirmEmail(string userId, string token)
{
    User user = await _userManager.FindByIdAsync(userId);
    if (user != null)
    {
var result = await _userManager.ConfirmEmailAsync(user, token);
return result.Succeeded;
    }

    return false;
}

忘记密码

public async Task GeneratePasswordTokenAndSendEmailAsync(string email)
{
    var user = await _userManager.FindByNameAsync(email);
    if (user != null && await _userManager.IsEmailConfirmedAsync(user))
    {
string token = await _userManager.GeneratePasswordResetTokenAsync(user);
string callbackUrl = this._urlHelper.Action("ResetPassword", "Account", new ConfirmTokenViewModel(user.Id, token), protocol: this._contextAccessor.HttpContext.Request.Scheme);

await this._emailService.SendAsync(
    to: user.Email,
    subject: "Reset password",
    body: "Reset your password by clicking this link: <a href=\"" + callbackUrl + "\">link</a>"
});
    }
}

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> ResetPassword(ResetPasswordViewModel model)
{
    if (ModelState.IsValid)
    {
IdentityResult result = await this._accountsManager.ResetPasswordAsync(model);
if (result.Succeeded)
{
    return RedirectToAction(nameof(ResetPasswordConfirmation), "Account");
}
else
    ModelState.AddModelErrors(result.Errors);
    }

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

public async Task<IdentityResult> ResetPasswordAsync(ResetPasswordViewModel model)
{
    IdentityResult result = IdentityResult.Success;

    if (model != null && !string.IsNullOrWhiteSpace(model.UserId))
    {
User user = await _userManager.FindByIdAsync(model.UserId);
if (user != null)
    result = await _userManager.ResetPasswordAsync(user, model.Token, model.Password);
    }

    return result;
}
