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; namespace DllLibrary.SendEmail { /// <summary> /// 发送邮件的类 /// </summary> public class Email { private MailMessage mMailMessage; //主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等) 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) private bool mEnableSsl; //是否对邮件内容进行socket层加密传输 private bool mEnablePwdAuthentication; //是否对发件人邮箱进行密码验证 ///<summary> /// 构造函数 ///</summary> ///<param name="server">发件箱的邮件服务器地址</param> ///<param name="toMail">收件人地址(可以是多个收件人,程序中是以“;"进行区分的)</param> ///<param name="fromMail">发件人地址</param> ///<param name="subject">邮件标题</param> ///<param name="emailBody">邮件内容(可以以html格式进行设计)</param> ///<param name="username">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)</param> ///<param name="password">发件人邮箱密码</param> ///<param name="port">发送邮件所用的端口号(htmp协议默认为25)</param> ///<param name="sslEnable">true表示对邮件内容进行socket层加密传输,false表示不加密</param> ///<param name="pwdCheckEnable">true表示对发件人邮箱进行密码验证,false表示不对发件人邮箱进行密码验证</param> public Email(string server, string toMail, string fromMail, string subject, string emailBody, string username, string password, string port, bool sslEnable, bool pwdCheckEnable) { try { mMailMessage = new MailMessage(); mMailMessage.To.Add(toMail); mMailMessage.From = new MailAddress(fromMail); mMailMessage.Subject = subject; mMailMessage.Body = emailBody; mMailMessage.IsBodyHtml = true; mMailMessage.BodyEncoding = System.Text.Encoding.UTF8; mMailMessage.Priority = MailPriority.Normal; this.mSenderServerHost = server; this.mSenderUsername = username; this.mSenderPassword = password; this.mSenderPort = Convert.ToInt32(port); this.mEnableSsl = sslEnable; this.mEnablePwdAuthentication = pwdCheckEnable; } catch (Exception ex) { throw ex; //Console.WriteLine(ex.ToString()); } } ///<summary> /// 添加附件 ///</summary> ///<param name="attachmentsPath">附件的路径集合,以分号分隔</param> public void AddAttachments(string attachmentsPath) { try { string[] path = attachmentsPath.Split(';'); //以什么符号分隔可以自定义 Attachment data; ContentDisposition disposition; for (int i = 0; i < path.Length; i++) { data = new Attachment(path[i], MediaTypeNames.Application.Octet); disposition = data.ContentDisposition; disposition.CreationDate = File.GetCreationTime(path[i]); disposition.ModificationDate = File.GetLastWriteTime(path[i]); disposition.ReadDate = File.GetLastAccessTime(path[i]); mMailMessage.Attachments.Add(data); } } catch (Exception ex) { throw ex; //Console.WriteLine(ex.ToString()); } } /// <summary> /// 邮件的发送 /// </summary> /// <returns>发送成功返回true,否则返回false</returns> public bool Send() { try { if (mMailMessage != null) { mSmtpClient = new SmtpClient(); //mSmtpClient.Host = "smtp." + mMailMessage.From.Host; mSmtpClient.Host = this.mSenderServerHost; mSmtpClient.Port = this.mSenderPort; mSmtpClient.UseDefaultCredentials = false; mSmtpClient.EnableSsl = this.mEnableSsl; if (this.mEnablePwdAuthentication) { System.Net.NetworkCredential nc = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); //mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); //NTLM: Secure Password Authentication in Microsoft Outlook Express mSmtpClient.Credentials = nc.GetCredential(mSmtpClient.Host, mSmtpClient.Port, "NTLM"); } else { mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); } mSmtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; mSmtpClient.Send(mMailMessage); } } catch { return false; } return true; } } }
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>"); } } } }
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。。。
