Question

标题几乎说明了。有没有办法在不使用发送网格的情况下将电子邮件确认添加到我的应用程序？我的Azure帐户不允许我使用它，说它在我的区域中不可用，我似乎无法找到另一种解决方案。

Answer 1

我没有在我的网站上使用sendgrid进行电子邮件确认服务。我认为在流量较低的小型网站上没有任何意义。

我使用的是gmail SMTP服务，它的工作非常完美：

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Net.Mail;
using System.Web;

namespace MyProject.MyClasses
{
public class GmailEmailService : SmtpClient
{
    // Gmail user-name
    public string UserName { get; set; }

    public GmailEmailService():
        base( ConfigurationManager.AppSettings["GmailHost"], Int32.Parse(ConfigurationManager.AppSettings["GmailPort"]) )
    {
        //Get values from web.config file:
        this.UserName = ConfigurationManager.AppSettings["GmailUserName"];
        this.EnableSsl = Boolean.Parse( ConfigurationManager.AppSettings["GmailSsl"] );
        this.UseDefaultCredentials = false;
        this.Credentials = new System.Net.NetworkCredential(this.UserName, ConfigurationManager.AppSettings["GmailPassword"]);
    }


}

}

在Web.Config文件中

添加以下内容：

  <configSections>

      <appSettings>

        <!--Smptp Server (confirmations emails)-->
        <add key="GmailUserName" value="[your user name]@gmail.com"/>
        <add key="GmailPassword" value="[your password]"/>
        <add key="GmailHost" value="smtp.gmail.com"/>
        <add key="GmailPort" value="587"/>
        <add key="GmailSsl" value="true"/>

      </appSettings>

  </configSections>

在App_Start \ IdentityConfig.cs文件中，将SendAsync方法更改为以下代码：

public class EmailService : IIdentityMessageService
{
public async Task SendAsync(IdentityMessage message)
{

        MailMessage email = new MailMessage(new MailAddress("noreply@myproject.com", "(do not reply)"), 
            new MailAddress(message.Destination));

        email.Subject = message.Subject;
        email.Body = message.Body;

        email.IsBodyHtml = true;

    using( var mailClient = new MyProject.MyClasses.GmailEmailService() )
    {
        //In order to use the original from email address, uncomment this line:
        //email.From = new MailAddress(mailClient.UserName, "(do not reply)");

        await mailClient.SendMailAsync(email);
    }

}
}

注意：您还必须将此用法添加到IdentityConfig.cs文件中：

using System.Net.Mail;

最后一件事是将AccountController文件中的以下内容更新为：

//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser { UserName = model.UserName, Email = model.Email };
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            //Comment the following line to prevent log in until the user is confirmed:
            //await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

            string callbackUrl = await SendEmailConfirmationTokenAsync(user.Id, "Account confirmation");

            // Uncomment to debug locally 
            // TempData["ViewBagLink"] = callbackUrl;

            ViewBag.errorMessage = "Please confirm the email was sent to you.";
            return View("ShowMsg");
        }
        AddErrors(result);
    }

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


//
// GET: /Account/ConfirmEmail
[AllowAnonymous]
public async Task<ActionResult> ConfirmEmail(string userId, string code)
{
    if (userId == null || code == null)
    {
        return View("Error");
    }
    var result = await UserManager.ConfirmEmailAsync(userId, code);
    return View(result.Succeeded ? "ConfirmEmail" : "Error");
}


private async Task<string> SendEmailConfirmationTokenAsync(string userID, string subject)
{
    // 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.GenerateEmailConfirmationTokenAsync(userID);
    var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = userID, code = code }, protocol: Request.Url.Scheme);
    await UserManager.SendEmailAsync(userID, subject, "Please confirm your account by <a href=\"" + callbackUrl + "\">clicking here</a>");


    return callbackUrl;
}

可能的视图ShowMsg.cs文件可以是：

@{
    ViewBag.Title = "Message";
}

<h1 class="text-danger">@ViewBag.Title</h1>
@{
    if (String.IsNullOrEmpty(ViewBag.errorMessage))
    {
        <h3 class="text-danger">An error occurred while processing your request.</h3>
    }
    else
    {
        <h3 class="text-danger">@ViewBag.errorMessage</h3>
    }
}

那就是它！它对我有用。

<强> P.S：你必须允许＆＃34; less-secure-apps＆＃34;您的Gmail帐户中的选项。 follow that gmail link
