1.配置邮箱

1.1 设置

1.2账户

1.3 开启邮箱服务

1.4 生成授权码

2 默认的SmtpEmailSender发送邮件

2.1 生成数据库

先修改数据库配置文件，执行迁移 ，不然项目启动不起来

2.2 添加一个后台任务执行发送邮件

Module文件的OnApplicationInitialization方法：

public override void OnApplicationInitialization(ApplicationInitializationContext context)
    {
        ......
        #region 后台服务
        context.AddBackgroundWorkerAsync<MailWorker>();
        #endregion
    }

2.3 服务中注入ISmtpEmailSender

public class MailWorker : AsyncPeriodicBackgroundWorkerBase
    {
        private readonly ISmtpEmailSender _emailSender;
        private readonly ISettingEncryptionService _settingEncryptionService;
        private readonly ISettingDefinitionManager settingDefinitionManager;

        public MailWorker(
            AbpAsyncTimer timer,
            IServiceScopeFactory serviceScopeFactory, ISmtpEmailSender emailSender, ISettingEncryptionService settingEncryptionService, ISettingDefinitionManager settingDefinitionManager
        ) : base(
            timer,
            serviceScopeFactory)
        {
            Timer.Period = 4000; //4s
            _emailSender = emailSender;
            _settingEncryptionService = settingEncryptionService;
            this.settingDefinitionManager = settingDefinitionManager;
        }

        protected async override Task DoWorkAsync(
            PeriodicBackgroundWorkerContext workerContext)
        {
            var setting = settingDefinitionManager.Get(EmailSettingNames.Smtp.Password);
            var ss = _settingEncryptionService.Encrypt(setting, "zuqdlkgeyiyobbcd");
            Logger.LogInformation("Starting: sending...");
            await _emailSender.SendAsync(
                   "***@foxmail.com", "测试发送邮件", "how are you?"
                );
            Logger.LogInformation("Completed: ending...");
        }
    }

2.4 在配置文件添加邮箱信息

{
  "App": {
    "SelfUrl": "https://localhost:44370"
  },
  "ConnectionStrings": {
    "Default": "Server=.;Database=SmtpEmailDemo;Uid=sa;Pwd=qwe123!;TrustServerCertificate=true"
  },
  "Settings": {
    "Abp.Mailing.Smtp.Host": "smtp.qq.com",
    "Abp.Mailing.Smtp.Port": "587",
    "Abp.Mailing.Smtp.UserName": "***@qq.com",
    "Abp.Mailing.Smtp.Password": "zuqdlkgeyiyobbcd",
    "Abp.Mailing.Smtp.Domain": "",
    "Abp.Mailing.Smtp.EnableSsl": "true",
    "Abp.Mailing.Smtp.UseDefaultCredentials": "false",
    "Abp.Mailing.DefaultFromAddress": "***@qq.com",
    "Abp.Mailing.DefaultFromDisplayName": "***@qq.com"
  },
  "StringEncryption": {
    "DefaultPassPhrase": "Yslb62n5falmPABy"
  }
}

注意端口号是587 密码不用自己去加密，直接填写邮箱授权码就行，UseDefaultCredentials为false

3 集成MailKit发送邮件

重复2.1，2.2步骤

3.1 添加包Volo.Abp.MailKit

3.2 Module文件配置依赖

typeof(AbpMailKitModule)

3.3 服务中注入IEmailSender

public class MailWorker : AsyncPeriodicBackgroundWorkerBase
    {
        private readonly IEmailSender _emailSender;
        public MailWorker(
            AbpAsyncTimer timer,
            IServiceScopeFactory serviceScopeFactory, IEmailSender emailSender
        ) : base(
            timer,
            serviceScopeFactory)
        {
            Timer.Period = 4000; //4s
            _emailSender = emailSender;  
        }

        protected async override Task DoWorkAsync(
            PeriodicBackgroundWorkerContext workerContext)
        {
            Logger.LogInformation("Start: starting...");
            await _emailSender.SendAsync(
                   "***@foxmail.com", "测试发送邮件", "how are you?"
                );
            Logger.LogInformation("Completed: ending...");
        }
    }

3.4 在配置文件添加邮箱信息

{
  "App": {
    "SelfUrl": "https://localhost:44373"
  },
  "ConnectionStrings": {
    "Default": "Server=.;Database=MailTest;Uid=sa;Pwd=qwe123!;TrustServerCertificate=true"
  },
  "Settings": {
    "Abp.Mailing.Smtp.Host": "smtp.qq.com",
    "Abp.Mailing.Smtp.Port": "465",
    "Abp.Mailing.Smtp.UserName": "***@qq.com",
    "Abp.Mailing.Smtp.Password": "zuqdlkgeyiyobbcd",
    "Abp.Mailing.Smtp.Domain": "",
    "Abp.Mailing.Smtp.EnableSsl": "true",
    "Abp.Mailing.Smtp.UseDefaultCredentials": "false",
    "Abp.Mailing.DefaultFromAddress": "***@qq.com",
    "Abp.Mailing.DefaultFromDisplayName": "***@qq.com"
  },
  "StringEncryption": {
    "DefaultPassPhrase": "sSMpfXfpBMcXS9Iz"
  }
}

注意端口号是465 密码不用自己去加密，直接填写邮箱授权码就行，UseDefaultCredentials为false
