asp.net core 2.0 邮件发送服务

　　网上找了一下，发现一个很不错的邮件发送服务Mailgun，首先要注册Mailgun账号，获得apikey以及domainame；

　　然后项目中安装nuget：

　　

　　配置并注册服务：

　　

　　public interface IEmailSender
    {
        Task SendEmailAsync(string email, string subject, string message);
    }

　　

　　public class EmailSender:IEmailSender
    {
        private readonly EmailSettings _emailSettings;

        public EmailSender(IOptions<EmailSettings> emailOptions)
        {
            _emailSettings = emailOptions.Value;
        }

        public Task SendEmailAsync(string account, string subject, string mess)
        {
            var domainName = _emailSettings.DomainName;
            var apiKey = _emailSettings.ApiKey;
            var sender = new MailgunSender(domainName, apiKey);
            Email.DefaultSender = sender;
            var email = Email.From(_emailSettings.From, "XXXXXXX平台")
                .To(account)
                .Subject(subject)
                .Body(mess);
            return email.SendAsync();
        }
    }

 

　　public class EmailSettings
    {
        public string ApiKey { get; set; }
        public string ApiBaseUri { get; set; }
        public string RequestUri { get; set; }
        public string From { get; set; }
        public  string DomainName { get; set; }
    }

 　　　　　　　#region 注册邮件服务
            services.Configure<EmailSettings>(Configuration.GetSection("EmailSettings"));
            services.AddTransient<IEmailSender, EmailSender>();
            #endregion

　　调用：

　　public class TestController : Controller
    {
        private readonly IOptions<EmailSettings> _emailOptions;
        private readonly ILogger<TestController> _logger;
        private readonly IEmailSender _emailSender;

        public TestController(IOptions<EmailSettings> emailOptions,ILogger<TestController> logger,IEmailSender emailSender)
        {
            _emailOptions = emailOptions;
            _logger = logger;
            _emailSender = emailSender;
        }
        public async Task<IActionResult> Index()
        {
            try
            {
                string code = "259878";
                await _emailSender.SendEmailAsync("3sdaasdadasdad6@qq.com",EmailType.Captcha ,$"验证码：{code}，如非本人操作请忽略。");
                _logger.LogInformation("发送邮件，to："+"3asdasdadad6@qq.com"+",类型："+EmailType.Captcha);
                return Content("ok");
            }
            catch (Exception e)
            {
                return Content("出错了："+e.Message);
            }
            
        }
    }
