ASP.NET MVC 模块与组件(一)——发送邮件

   

  我的见解:

  模块化与组件化是编程的一种思想:提高代码的重用性,提高开发效率。

  常见的模块化就是函数与各种类型的封装,若是代码具有更高的重用价值(能够提供给别人使用),建议可以考虑封装成动态链接库(dll),直接引用使用。

  常见的组件化就是将各种需求功能封装成一系列完整的文档(比模块化要求更高、更完整),要用的时候直接引用对应的文件就可以使用。

 

  说了那么多,我们就直奔今天的主题:在用ASP.NET 技术开发Web网站的时候,如何实现发送邮件的功能?

  下面的是一个专门用来发送邮件的类(封装好了,可以直接编译成动态链接库,方便以后重复使用)(默认是以Html格式发送的邮件)

using System;
using System.IO;
using System.Net.Mail;
using System.Net.Mime;

        private SmtpClient mSmtpClient; //主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等)
        private int mSenderPort;   //发送邮件所用的端口号(htmp协议默认为25)
        private string mSenderServerHost;    //发件箱的邮件服务器地址(IP形式或字符串形式均可)
        private string mSenderPassword;    //发件箱的密码
        private string mSenderUsername;   //发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello)

  使用这个发送邮箱类的实例代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using Test.Models;
using DllLibrary.SendEmail;//引入对应命名空间

namespace Test.Controllers
{
    public class HomeController : Controller
    {
    
        /// <summary>
        /// 发送邮件
        /// </summary>
        /// <param name="title">邮件主题</param>
        /// <param name="email">要发送对象的邮箱</param>
        /// <param name="content">邮件内容</param>
        /// <returns></returns>
         public ActionResult SendMail(string title, string email, string content)
        {
                string senderServerIp = "smtp.163.com";   //使用163代理邮箱服务器(也可是使用qq的代理邮箱服务器,但需要与具体邮箱对相应)
                string toMailAddress = email;              //要发送对象的邮箱
                string fromMailAddress = "XXXXXX@163.com";//你的邮箱
                string subjectInfo = title;                  //主题
                string bodyInfo = "<p>" + content  + "</p>";//以Html格式发送的邮件
                string mailUsername = "XXX";              //登录邮箱的用户名
                string mailPassword = "xomeagyungxzhsxf"; //对应的登录邮箱的第三方密码(你的邮箱不论是163还是qq邮箱,都需要自行开通stmp服务)
                string mailPort = "25";                      //发送邮箱的端口号
                //string attachPath = "E:\\123123.txt; E:\\haha.pdf";

                //创建发送邮箱的对象
                Email myEmail = new Email(senderServerIp, toMailAddress, fromMailAddress, subjectInfo, bodyInfo, mailUsername, mailPassword, mailPort, false, false);
                
                //添加附件
                //email.AddAttachments(attachPath);
                
                if (myEmail.Send())
                {
                    return Content("<script>alert('邮件已成功发送!')</script>");
                }
                else
                {
                    return Content("<script>alert('邮件发送失败!')</script>");
                }

        }
        
    }
}
View Code

  简单说明:要发送邮件,需要开通一个stmp服务的邮箱号。(可以到163官网申请一个163邮箱,并且开通stmp服务就可以了(注:示例代码中所使用的密码是在开通stmp服务时,单独发送的第三方登录密码,而不是登录邮箱的密码))

  好了,这次分享就到这里了,下次继续。。。
