近日研究了下IBM Lotus Mail，这货果然是麻烦，由于公司策略，没有开放smtp，很多系统邮件都没有办法发送，于是入手google学习Lotus Mail，想做成Windows服务，提供wcf服务给内部应用系统使用。在google上找了很多资料，由于是系统邮件，很多东西配置起来又比较麻烦。自己也入了很多坑，特此作为记录。废话不多说，下面开始...

服务器环境：Windows Server 2008R2+Lotus Notes 8.5中文版

特别注意：Lotus Notes 8.5中文版需要配置好账户密码，但是不需要打开它。

本地环境：Lotus Notes 8.5中文版+Visual Studio 2013

~~~~~~~~~~~~~~~~~~~~~~~我是优雅的分隔符~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1，打开VS，新建类库项目LotusMailHelper，添加Lotus Domino Objects引用：

添加完之后VS会自动编译成dll

2，添加类Mail.cs，添加邮件发送方法SendMail：

<span style="color: #808080;">///</span> <span style="color: #808080;"><summary></summary></span>

<span style="color: #808080;">///</span><span style="color: #008000;"> 发送邮件

</span><span style="color: #808080;">///</span> <span style="color: #808080;"></span>

<span style="color: #808080;">///</span> <span style="color: #808080;"><param name="sendTo"></span>

<span style="color: #808080;">///</span> <span style="color: #808080;"><param name="subject"></span>

<span style="color: #808080;">///</span> <span style="color: #808080;"><param name="messageBody"></span>

<span style="color: #0000ff;">public</span> <span style="color: #0000ff;">bool</span> SendMail(<span style="color: #0000ff;">string</span>[] sendTo, <span style="color: #0000ff;">string</span> subject, <span style="color: #0000ff;">string</span> messageBody)

3，在Mail.cs添加Using:using Domino;

4，编写SendMail的逻辑

Domino.Notessession nSession = <span style="color: #0000ff;">new</span><span style="color: #000000;"> Domino.NotesSession();
</span><span style="color: #0000ff;">string</span> pwd = System.Configuration.ConfigurationManager.AppSettings[<span style="color: #800000;">"</span><span style="color: #800000;">LotusMailPassWord</span><span style="color: #800000;">"</span>];<span style="color: #008000;">//</span><span style="color: #008000;">lotus邮箱密码</span>

<span style="color: #0000ff;">if</span> (saveMessageOnSend == <span style="color: #800000;">"</span><span style="color: #800000;">1</span><span style="color: #800000;">"</span>)<span style="color: #008000;">//</span><span style="color: #008000;">为1时保存到lotus的发件箱</span>
<span style="color: #000000;">{
    nDocument.SaveMessageOnSend </span>= <span style="color: #0000ff;">true</span><span style="color: #000000;">;
}
</span><span style="color: #0000ff;">else</span><span style="color: #000000;">
{
    nDocument.SaveMessageOnSend </span>= <span style="color: #0000ff;">false</span>;<span style="color: #008000;">//</span><span style="color: #008000;">设置保存与否</span>
<span style="color: #000000;">}
NotesStream HtmlBody </span>=<span style="color: #000000;"> nSession.CreateStream();
HtmlBody.WriteText(messageBody);</span><span style="color: #008000;">//</span><span style="color: #008000;">构建HTML邮件，可以在头和尾添加公司的logo和系统提醒语</span>
NotesMIMEEntity mine = nDocument.CreateMIMEEntity(<span style="color: #800000;">"</span><span style="color: #800000;">Body</span><span style="color: #800000;">"</span>);<span style="color: #008000;">//</span><span style="color: #008000;">构建邮件正文</span>
mine.SetContentFromText(HtmlBody, <span style="color: #800000;">"</span><span style="color: #800000;">text/html;charset=UTF-8</span><span style="color: #800000;">"</span><span style="color: #000000;">, Domino.MIME_ENCODING.ENC_IDENTITY_BINARY);
nDocument.AppendItemValue(</span><span style="color: #800000;">"</span><span style="color: #800000;">PRincipal</span><span style="color: #800000;">"</span>, <span style="color: #800000;">"</span><span style="color: #800000;">XXX管理员</span><span style="color: #800000;">"</span>);<span style="color: #008000;">//</span><span style="color: #008000;">设置邮件的发件人昵称</span>

nDocument.CloseMIMEEntities();<span style="color: #008000;">//</span><span style="color: #008000;">关闭</span>

由于最后会封装为dll，最好是添加try...catch...，加以优化，下面为优化过后：

}</span>

5，点击项目生成，找到Bin文件夹中的dll，保存到自己喜欢的文件夹，方便后期的调用

============我是更加优美的分隔符=============

下面一起来建立Windows service

1，打开VS，新建Windows服务项目

名字随便取。。。新建完成之后会自动生成Service1.cs，打开Service1.cs代码看看，主要分为以下几个方法：

<span style="color: #0000ff;">public</span> <span style="color: #0000ff;">partial</span> <span style="color: #0000ff;">class</span><span style="color: #000000;"> Service1 : ServiceBase
{
    </span><span style="color: #0000ff;">public</span><span style="color: #000000;"> Service1()
    {
        InitializeComponent();
    }
    
    </span><span style="color: #0000ff;">protected</span> <span style="color: #0000ff;">override</span> <span style="color: #0000ff;">void</span> OnStart(<span style="color: #0000ff;">string</span><span style="color: #000000;">[] args)
    {
    }
    
    </span><span style="color: #0000ff;">protected</span> <span style="color: #0000ff;">override</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> OnStop()
    {
    }
}</span>

OnStart：主要是写入要启动的逻辑代码

<span>OnStop：主要写的是停止服务时要执行的方法，也就是逻辑代码，我一般会将日志写在这<br></span>

2，将service1.cs删除，新建一个Windows服务，并命名成公司要求的。例如我的是MailService.cs。

3，新建一个处理邮件的方法：

<span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> SendMail()
{
    </span><span style="color: #0000ff;">while</span>(<span style="color: #0000ff;">true</span><span style="color: #000000;">)
    {
        </span><span style="color: #008000;">//</span><span style="color: #008000;">这里写邮件数据获取以及发送邮件</span>
        Thread.Sleep(<span style="color: #800080;">100</span><span style="color: #000000;">);
    }   
}</span>

4，构建邮件model:在解决方案点击鼠标右键添加新建项目，选择类库项目，MailModel，新建MailInfo.cs

<span style="color: #0000ff;">public</span> <span style="color: #0000ff;">class</span><span style="color: #000000;"> MailInfo
{
    </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">string</span> mailId { <span style="color: #0000ff;">get</span>; <span style="color: #0000ff;">set</span><span style="color: #000000;">; }
    </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">string</span>[] sendTo { <span style="color: #0000ff;">get</span>; <span style="color: #0000ff;">set</span><span style="color: #000000;">; }
    </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">string</span> subject { <span style="color: #0000ff;">get</span>; <span style="color: #0000ff;">set</span><span style="color: #000000;">; }
    </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">string</span> mailBody { <span style="color: #0000ff;">get</span>; <span style="color: #0000ff;">set</span><span style="color: #000000;">; }
}</span>

5，新建类库DbHelper，添加类Mail.cs，在里面写GetMailData()方法，RemoveMailData(),GetMailCount(),InsertMailData()等方法，这里由于涉及到公司的信息，不是很方便写出来。大家可以自行添加进去

<span style="color: #0000ff;">public</span><span style="color: #000000;"> MailModel.MailInfo GetMailData()
{
    </span><span style="color: #008000;">//</span><span style="color: #008000;">这里写获取邮件数据</span>
    <span style="color: #0000ff;">return</span> MailInfo;<span style="color: #008000;">//</span><span style="color: #008000;">返回数据库第一封待发邮件数据</span>
<span style="color: #000000;">}
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span> RemoveMailData(<span style="color: #0000ff;">string</span><span style="color: #000000;"> mailId)
{
    </span><span style="color: #008000;">//</span><span style="color: #008000;">删除数据库中指定id的邮件数据</span>
<span style="color: #000000;">}
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">long</span><span style="color: #000000;"> GetMailCount()
{
    </span><span style="color: #008000;">//</span><span style="color: #008000;">这里写获取邮件数量</span>
    <span style="color: #0000ff;">return</span><span style="color: #000000;"> 邮件数量
}
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">bool</span><span style="color: #000000;"> InsertMailData()
{
    </span><span style="color: #008000;">//</span><span style="color: #008000;">这里写插入一封邮件数据</span>
    <span style="color: #0000ff;">return</span> <span style="color: #0000ff;">true</span><span style="color: #000000;">;
}</span>

6，新建类库WCF项目，添加wcf，名字为SendMail

添加完成之后VS会自动生成ISendMail.cs和SendMail.cs。打开ISendMail.cs会看到如下代码

<span style="color: #008000;">//</span><span style="color: #008000;"> 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“ISendMail”。</span>
<span style="color: #000000;">[ServiceContract]
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">interface</span><span style="color: #000000;"> ISendMail
{
    [OperationContract]
    </span><span style="color: #0000ff;">void</span><span style="color: #000000;"> DoWork();
}</span>

里面只有一个DoWork方法，我们新建一个ApplySendMail();注意：在顶上要添加[OperationContract]否则不会公开该函数。最后的ISendMail.cs代码如下

<span style="color: #000000;">[ServiceContract]
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">interface</span><span style="color: #000000;"> ISendMail
{
    [OperationContract]
    </span><span style="color: #0000ff;">string</span> ApplySendMail(<span style="color: #0000ff;">string</span>[] sendTo, <span style="color: #0000ff;">string</span> subject, <span style="color: #0000ff;">string</span> body, <span style="color: #0000ff;">string</span><span style="color: #000000;"> password);
}</span>

接着打开SendMail.cs，去实现接口的ApplySendMail()方法

<span style="color: #0000ff;">public</span> <span style="color: #0000ff;">class</span><span style="color: #000000;"> SendMail : ISendMail
{
    </span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">string</span> ApplySendMail(<span style="color: #0000ff;">string</span>[] sendTo, <span style="color: #0000ff;">string</span> subject, <span style="color: #0000ff;">string</span> body, <span style="color: #0000ff;">string</span><span style="color: #000000;"> password)
    {
        </span><span style="color: #0000ff;">string</span> result = <span style="color: #0000ff;">string</span><span style="color: #000000;">.Empty;
        </span><span style="color: #0000ff;">string</span> mailPassword = System.Configuration.ConfigurationManager.AppSettings[<span style="color: #800000;">"</span><span style="color: #800000;">password</span><span style="color: #800000;">"</span><span style="color: #000000;">];
        </span><span style="color: #0000ff;">if</span> (mailPassword ==<span style="color: #000000;"> password)
        {
            </span><span style="color: #0000ff;">try</span><span style="color: #000000;">
            {
                MailModel.MailInfo mail </span>= <span style="color: #0000ff;">new</span><span style="color: #000000;"> MailModel.MailInfo
                {
                    sendTo </span>=<span style="color: #000000;"> sendTo,
                    subject </span>=<span style="color: #000000;"> subject,
                    mailBody </span>=<span style="color: #000000;"> body
                };
                </span><span style="color: #0000ff;">long</span> count =<span style="color: #000000;"> DbHelper.Mail.GetMailCount();
                </span><span style="color: #0000ff;">if</span><span style="color: #000000;"> (DbHelper.Mail.InsertMailData(mail))
                {
                    result </span>= <span style="color: #0000ff;">string</span>.Format(<span style="color: #800000;">"</span><span style="color: #800000;">提交成功.前面大約還有：{0}個任務</span><span style="color: #800000;">"</span><span style="color: #000000;">, count);
                }
                </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> result;
            }
            </span><span style="color: #0000ff;">catch</span><span style="color: #000000;">
            {
                </span><span style="color: #0000ff;">return</span> <span style="color: #800000;">"</span><span style="color: #800000;">提交失敗</span><span style="color: #800000;">"</span><span style="color: #000000;">;
            }
        }
        </span><span style="color: #0000ff;">else</span><span style="color: #000000;">
        {
            </span><span style="color: #0000ff;">return</span> <span style="color: #800000;">"</span><span style="color: #800000;">密码错误，无法提交</span><span style="color: #800000;">"</span><span style="color: #000000;">;
        }
    }
}</span>

至此wcf基础已经可以了，下面继续完成Windows服务那一块

7，完成处理邮件的方法SendMail()，这里要添加之前写好的LoutusMailHelper.dll

<span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> SendMail()
{
    </span><span style="color: #0000ff;">while</span>(<span style="color: #0000ff;">true</span><span style="color: #000000;">)
    {
        </span><span style="color: #0000ff;">var</span> mailData=<span style="color: #000000;">DbHelper.Mail.GetMailData();
        </span><span style="color: #0000ff;">if</span>(mailData!=<span style="color: #0000ff;">null</span><span style="color: #000000;">)
        {
            </span><span style="color: #0000ff;">if</span><span style="color: #000000;">(LotusMailHelper.Mail.SendMail(mailData.sendTo,mailData.subject,mailData.mailBody))
            {
                DbHelper.Mail.RemoveMailData(mailData.mailId);
            }
            Thread.Sleep(</span><span style="color: #800080;">100</span>);<span style="color: #008000;">//</span><span style="color: #008000;">休息0.1秒</span>
<span style="color: #000000;">        }
        </span><span style="color: #0000ff;">else</span><span style="color: #000000;">
        {
            Thread.Sleep(</span><span style="color: #800080;">10000</span>);<span style="color: #008000;">//</span><span style="color: #008000;">休息10秒钟</span>
<span style="color: #000000;">        }       
    }   
}</span>

8，完成OnStart()逻辑：①，先添加私有成员到MailService.cs

<span style="color: #0000ff;">partial</span> <span style="color: #0000ff;">class</span><span style="color: #000000;"> MailService : ServiceBase
{
    </span><span style="color: #0000ff;">public</span><span style="color: #000000;"> MailService()
    {
        InitializeComponent();
    }
    </span><span style="color: #0000ff;">private</span><span style="color: #000000;"> System.ServiceModel.ServiceHost _host;
    
    </span><span style="color: #008000;">/*</span><span style="color: #008000;">
    此处省略部分代码
    </span><span style="color: #008000;">*/</span><span style="color: #000000;">
}</span>

②，编写OnStart()代码

<span style="color: #0000ff;">protected</span> <span style="color: #0000ff;">override</span> <span style="color: #0000ff;">void</span> OnStart(<span style="color: #0000ff;">string</span><span style="color: #000000;">[] args)
{
    _host </span>= <span style="color: #0000ff;">new</span> System.ServiceModel.ServiceHost(<span style="color: #0000ff;">typeof</span><span style="color: #000000;">(WCF.Mail));
    _host.Open();
    </span><span style="color: #008000;">//</span><span style="color: #008000;">启动wcf服务
    
    </span><span style="color: #008000;">//</span><span style="color: #008000;">启动一个线程专门轮询发送邮件</span>
    Thread sendMail = <span style="color: #0000ff;">new</span> Thread(<span style="color: #0000ff;">new</span><span style="color: #000000;"> ThreadStart(SendMail));
    sendMail.IsBackground </span>= <span style="color: #0000ff;">true</span><span style="color: #000000;">;
    sendMail.Start();
}</span>

9，编写OnStop()代码，添加日志记录代码

10，配置App.config，wcf一定要配置。先看App.config中是否存在system.serviceModel节点，存在的话只需修改部分字段即可，不存在的话添加如下：

<system.servicemodel>
    <behaviors>
      <servicebehaviors>
        <behavior name="<span" style="color: #800000;">"">
          <servicemetadata httpgetenabled="<span" style="color: #800000;">"<span style="color: #800000;">true</span><span style="color: #800000;">"</span> httpsGetEnabled=<span style="color: #800000;">"</span><span style="color: #800000;">true</span><span style="color: #800000;">"</span> />
          <servicedebug includeexceptiondetailinfaults="<span" style="color: #800000;">"<span style="color: #800000;">false</span><span style="color: #800000;">"</span> />
        </servicedebug></servicemetadata></behavior>
      </servicebehaviors>
    </behaviors>
    <services>
      <service name="<span" style="color: #800000;">"<span style="color: #800000;">WCF.Mail</span><span style="color: #800000;">"</span>>
        <endpoint address="<span" style="color: #800000;">"" binding=<span style="color: #800000;">"</span><span style="color: #800000;">basicHttpBinding</span><span style="color: #800000;">"</span> contract=<span style="color: #800000;">"</span><span style="color: #800000;">WCF.IMail</span><span style="color: #800000;">"</span>>
          <identity>
            <dns value="<span" style="color: #800000;">"<span style="color: #800000;">localhost</span><span style="color: #800000;">"</span> />
          </dns></identity>
        </endpoint>
        <endpoint address="<span" style="color: #800000;">"<span style="color: #800000;">mex</span><span style="color: #800000;">"</span> binding=<span style="color: #800000;">"</span><span style="color: #800000;">mexHttpBinding</span><span style="color: #800000;">"</span> contract=<span style="color: #800000;">"</span><span style="color: #800000;">IMetadataExchange</span><span style="color: #800000;">"</span> />
        <!--wcf节点配置开始-->
        <host>
          <baseaddresses>
            <add baseaddress="<span" style="color: #800000;">"<span style="color: #800000;">http://localhost:8733/MailService/Mail/</span><span style="color: #800000;">"</span> />
          </add></baseaddresses>
        </host>
        <!--wcf节点配置结束-->
      </endpoint></service>
    </services>
  </system.servicemodel>

~~至此，基本的都已经完成，下面到Windows service部署

1，打开MailService.cs视图界面，添加安装程序。会自动出现如下界面：

选中serviceProcessInstaller1组件，查看属性，设置account为LocalSystem

选中serviceInstaller1组件，查看属性

设置ServiceName的值，该值表示在系统服务中的名称

设置StartType，如果为Manual则手动启动，默认停止，如果为Automatic为自动启动

设置Description，添加服务描述

2，重新生成项目

3，打开Windows的cmd，输入C:\Windows\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe exe路径

等待安装。安装完毕之后打开计算机管理，查看服务，点击启动。

***删除服务：sc delete 服务名

至此，所有步骤都完成了，可以畅快的调用wcf来发送系统邮件了
