如何修复电子邮件确认-在.NET Core中，它不起作用 [英] How can I fix email confirmation - in .NET Core, it doesn't work
问题描述
我已经有注册操作
public async Task<IActionResult> OnPostAsync(string returnUrl = null)
{
var useremail = _userManager.Users.FirstOrDefault(u => u.Email.ToLower() == Input.Email.ToLower());
if (useremail == null)
{
returnUrl = returnUrl ?? Url.Content("~/");
ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
if (ModelState.IsValid)
{
var user = new IdentityUser { UserName = Input.UserName, Email = Input.Email };
var result = await _userManager.CreateAsync(user, Input.Password);
if (result.Succeeded)
{
_logger.LogInformation("User created a new account with password.");
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
code = WebEncoders.Base64UrlEncode(Encoding.UTF8.GetBytes(code));
var callbackUrl = Url.Page(
"/Account/ConfirmEmail",
pageHandler: null,
values: new { area = "Identity", userId = user.Id, code = code },
protocol: Request.Scheme);
await _emailSender.SendEmailAsync(Input.Email, "Confirm your email",
$"Please confirm your account by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");
if (_userManager.Options.SignIn.RequireConfirmedAccount)
{
return RedirectToPage("RegisterConfirmation", new { email = Input.Email });
}
else
{
await _signInManager.SignInAsync(user, isPersistent: false);
return LocalRedirect(returnUrl);
}
}
foreach (var error in result.Errors)
{
ModelState.AddModelError(string.Empty, error.Description);
}
}
}
// If we got this far, something failed, redisplay form
ViewData["EmailExists"] = "Try another email that one is used";
return Page();
}
然后我创建了sendgrid用户和密钥并通过CMD注册了它们，然后创建了发送电子邮件的操作
Then I created the sendgrid user and key and registered them by CMD, then I created the action of send email
public class EmailSender : IEmailSender
{
public EmailSender(IOptions<AuthMessageSenderOptions>optionsAccessor)
{
Options = optionsAccessor.Value;
}
public AuthMessageSenderOptions Options { get; }
public Task SendEmailAsync (string email , string subject , string message)
{
return Excute(Options.SendGridKey,subject,message,email);
}
private Task Excute(string apiKey, string subject, string message, string email)
{
var client = new SendGridClient(apiKey);
var msg = new SendGridMessage()
{
From = new EmailAddress("darydress@yahoo.com", "dary dress"),
Subject = subject,
PlainTextContent = message,
HtmlContent = message
};
msg.AddTo(new EmailAddress(email));
msg.SetClickTracking(false, false);
return client.SendEmailAsync(msg);
}
}
然后在startup.cs中
Then in startup.cs
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(
Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<IdentityUser, IdentityRole>( options => options.SignIn.RequireConfirmedAccount = true)
.AddDefaultUI()
.AddDefaultTokenProviders()
.AddEntityFrameworkStores<ApplicationDbContext>();
services.AddControllersWithViews();
services.AddRazorPages();
services.AddMvc();
services.AddTransient<IEmailSender, EmailSender>();
services.Configure<AuthMessageSenderOptions>(Configuration);
services.AddPaging();
services.ConfigureApplicationCookie(o => {
o.ExpireTimeSpan = TimeSpan.FromDays(5);
o.SlidingExpiration = true;
});
services.AddMvc(options =>
{
options.Filters.Add(new RequireHttpsAttribute());
});
services.ConfigureApplicationCookie(options =>
{
options.AccessDeniedPath = new Microsoft.AspNetCore.Http.PathString("/Main/AccessDenied");
});
}
但是注册后发送电子邮件不起作用，这给了我一些我需要确认我的电子邮件的单词，并给了我确认我的电子邮件的链接，但没有将其发送给gmail
but sending an e-mail doesn't work after registration gives me some words that i need confirm my email and gives me link to confirm my email but doesn't send it to gmail
有人有想法吗?
我遵循了Microsoft的本文档 https://docs.microsoft.com/zh-cn/aspnet/core/security/authentication/accconfirm?view = aspnetcore-3.1& tabs = visual-studio
I followed this documentation from microsoft https://docs.microsoft.com/en-us/aspnet/core/security/authentication/accconfirm?view=aspnetcore-3.1&tabs=visual-studio
推荐答案
已解决"，我问Sendgrid，并被告知不能将yahoo电子邮件(或gmail，...)用作发件人电子邮件；这是答案的一部分:"Yahoo遵守称为DMARC的电子邮件安全标准.DMARC指示电子邮件提供商拒绝发件人"域为Yahoo域但邮件来自未经批准的域服务器/服务的邮件."所以我需要使用自己的邮件域；
"Solved" I asked Sendgrid, and I was told that I cannot use my yahoo email (or gmail,...) as the sender email; this is part of the answer: "Yahoo observes an email security standard called DMARC. DMARC instructs email providers to reject messages where the From domain is a Yahoo domain, but the message originates from a non-approved domain server/service." So I need to use my own mail domain;
