UserManager SendEmailAsync没有发送电子邮件

Question

我使用以下代码尝试异步发送电子邮件,但没有发送电子邮件,我不确定是什么做错了.我还在web.config中为电子邮件协议添加了第二段代码.

SendEmailAsync代码

await UserManager.SendEmailAsync(username.Id, "MTSS-B: Forgot Password", "Here is your new password. Please go back to the MTSS-B web tool and sign in. You will be prompted to create your own password.<br/><br/>" + tmpPass + "<br/><br/>MTSS-B Administrator");

Web.config代码

<system.net>
<mailSettings>
  <smtp>
    <network host="smtp1.airws.org" userName="" password="" />
  </smtp>
</mailSettings>
</system.net>

********更新

我测试了是否可以使用常规方法发送电子邮件,并且可以使用以下代码发送电子邮件.

MailMessage m = new MailMessage(new MailAddress(ConfigurationManager.AppSettings["SupportEmailAddr"]), new MailAddress(model.Email));
m.Subject = "MTSS-B: Forgot Password"; 
m.Body = string.Format("Here is your new password. Please go back to the MTSS-B web tool and sign in. You will be prompted to create your own password.<br/><br/>Password: " + tmpPass + "<br/><br/>MTSS-B Administrator"); 
m.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp2.airws.org"); 
smtp.Send(m);

在您的应用程序中,您可能IdentityConfig.cs在App_Start文件夹中调用了一个文件.该文件可能具有以下类似的功能:

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        return Task.FromResult(0);
    }
}

将其更改为:

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        SmtpClient client = new SmtpClient();
        return client.SendMailAsync(ConfigurationManager.AppSettings["SupportEmailAddr"], 
                                    message.Destination, 
                                    message.Subject, 
                                    message.Body);
    }
}

根据自己的喜好自定义发送代码.

Joe的解决方案引导了我很多,谢谢!但要为此做出贡献,您必须包含以下命名空间:

using System.Configuration;
using System.Net.Mail;

我做了很多尝试后,我已经改变了他的解决方案,我已经达到了一些有效的代码(它仍然必须被重新修改,但它不会改变这个想法),这就是我的SendAsync方法的样子:

public Task SendAsync(IdentityMessage message) {
    //SmtpClient client = new SmtpClient();
    //return client.SendMailAsync(ConfigurationManager.AppSettings["SupportEmailAddr"],
    //                            message.Destination,
    //                            message.Subject,
    //                            message.Body);

    SmtpClient client = new SmtpClient();
    client.Port = 587;
    client.Host = "smtp.gmail.com";
    client.EnableSsl = true;
    //client.Timeout = 10000;
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.UseDefaultCredentials = false;
    client.Credentials = new NetworkCredential("mailName@gmail.com", "mailPassword");

    return client.SendMailAsync("mailName@gmail.com", message.Destination, message.Subject, message.Body);
}

您可以看到Joe的解决方案在顶部进行了评论,然后,对SmtpClient进行了大量配置(由于我已经进行了一些测试,超时被评论,如果它符合您的需要,您可以取消注释).

之后,邮件以异步方式发送,注意发件人(Joe从AppSettings变量获取)与凭证中指定的相同(您必须创建一个gmail [或您想要的wathever邮件服务]帐户并使用它用于创建凭据的名称和密码).

这应该够了吧!请记住,gmail可能会在尝试以这种方式连接到您的新邮件帐户时使您的生活变得复杂,要解决此问题,您必须登录该帐户并转到您的帐户配置并激活"安全性较低的应用程序访问"(或者类似于,我说西班牙语,所以我的牵引可能不那么好......).

编辑22/04/16:看起来这个解决方案在处理代理服务器时无法正常工作,应该有一种方法来配置它.在我的情况下,我发现禁用代理并继续下去会更便宜,但对于那些负担不起的人来说,期望在实现这一点时遇到这个障碍.

我认为您正在使用Macrosoft ASP.NET身份和SMTP电子邮件客户端服务器.然后你的完整配置如下:

Web.config文件

<system.net>
<mailSettings>
  <smtp from="xyz@gmail.com">
    <network host="smtp.gmail.com" userName="xyz" defaultCredentials="false" password="xyz" port="587" enableSsl="true" />
  </smtp>
</mailSettings>
</system.net>

创建一个SmtpEmailService.cs类

public class SmtpEmailService : IIdentityMessageService
{
    readonly ConcurrentQueue<SmtpClient> _clients = new ConcurrentQueue<SmtpClient>();

    public async Task SendAsync(IdentityMessage message)
    {
        var client = GetOrCreateSmtpClient();
        try
        {
            MailMessage mailMessage = new MailMessage();

            mailMessage.To.Add(new MailAddress(message.Destination));
            mailMessage.Subject = message.Subject;
            mailMessage.Body = message.Body;

            mailMessage.BodyEncoding = Encoding.UTF8;
            mailMessage.SubjectEncoding = Encoding.UTF8;
            mailMessage.IsBodyHtml = true;

            // there can only ever be one-1 concurrent call to SendMailAsync
            await client.SendMailAsync(mailMessage);
        }
        finally
        {
            _clients.Enqueue(client);
        }
    }


    private SmtpClient GetOrCreateSmtpClient()
    {
        SmtpClient client = null;
        if (_clients.TryDequeue(out client))
        {
            return client;
        }

        client = new SmtpClient();
        return client;
    }
}

IdentityConfig.cs

// Configure the application user manager used in this application. 
//UserManager is defined in ASP.NET Identity and is used by the application.
public class ApplicationUserManager : UserManager<User>
{
    public ApplicationUserManager(IUserStore<User> store, IIdentityMessageService emailService)
        : base(store)
    {
        this.EmailService = emailService;
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new UserStore<User>(context.Get<ApplicationDbContext>()), new SmtpEmailService());
        .
        .
        .
        .
        return manager;
    }
}

如果您正在使用依赖注入(DI),那么配置它.我正在使用UnityContainer(UnityConfig.cs),所以我的配置是:

container.RegisterType<IIdentityMessageService, SmtpEmailService>();

最后从控制器中使用它:

public async Task<IHttpActionResult> TestSmtpMail()
{
    var subject = "Your subject";
    var body = "Your email body it can be html also";
    var user = await UserManager.FindByEmailAsync("xxx@gmail.com");
    await UserManager.SendEmailAsync(user.Id, subject, body);
    return Ok();
}

您可能会收到以下错误:

SMTP服务器需要安全连接或客户端未经过身份验证.

然后允许较少的安全应用和允许gmail帐户使其他应用可以访问
