這篇文章主要介紹C#中如何利用Lotus notes公共郵箱發(fā)送郵件,文中介紹的非常詳細,具有一定的參考價值,感興趣的小伙伴們一定要看完!
前言
公司的郵件系統(tǒng)用的是反人類的 Lotus notes, 你敢信?
最近要實現(xiàn)一個功能,郵件提醒功能,就是通過自動發(fā)送提醒郵件
前前后后這個問題搞了2天,由于公司的諸多條件限制,無法直接調(diào)用到公司發(fā)送郵件的接口,只有通過類似 Lotus script,VBA 等其他方式來實現(xiàn)。
用VBA代碼實現(xiàn)發(fā)送郵件,其實我在n年前就實現(xiàn)過了
代碼如下,網(wǎng)上一搜也一大堆
Function SendEmailbyNotesWithAttachement_2(Addresses, Attach, cc) strSubject = ThisWorkbook.Sheets("EMAIL").Range("B1") strbody = ThisWorkbook.Sheets("EMAIL").Range("A1") 'Declare Variables Dim s As Object Dim db As Object Dim body As Object Dim bodyChild As Object Dim header As Object Dim stream As Object Dim host As String Dim message As Object ' Notes variables Set s = CreateObject("Notes.NotesSession") Set db = s.CURRENTDATABASE Set stream = s.CreateStream ' Turn off auto conversion to rtf s.ConvertMIME = False ' Create message Set message = db.CREATEDOCUMENT message.Form = "memo" message.Subject = strSubject message.sendTo = Split(Addresses, ";") message.CopyTo = cc message.SaveMessageOnSend = True ' Create the body to hold HTML and attachment Set body = message.CreateMIMEEntity 'Child mime entity which is going to contain the HTML which we put in the stream Set bodyChild = body.CreateChildEntity() Call stream.WriteText(strbody) Call bodyChild.SetContentFromText(stream, "text/HTML;charset=UTF-8", ENC_NONE) Call stream.Close Call stream.Truncate ' This will run though an array of attachment paths and add them to the email For i = 0 To UBound(Attach) strAttach = Attach(i) If Len(strAttach) > 0 And Len(Dir(strAttach)) > 0 Then ' Get the attachment file name pos = InStrRev(strAttach, "\") Filename = Right(strAttach, Len(strAttach) - pos) 'A new child mime entity to hold a file attachment Set bodyChild = body.CreateChildEntity() Set header = bodyChild.CreateHeader("Content-Type") Call header.SetHeaderVal("multipart/mixed") Set header = bodyChild.CreateHeader("Content-Disposition") Call header.SetHeaderVal("attachment; filename=" & Filename) Set header = bodyChild.CreateHeader("Content-ID") Call header.SetHeaderVal(Filename) Set stream = s.CreateStream() If Not stream.Open(strAttach, "binary") Then MsgBox "Open failed" End If If stream.Bytes = 0 Then MsgBox "File has no content" End If Call bodyChild.SetContentFromBytes(stream, "application/octet-stream", ENC_IDENTITY_BINARY) ' All my attachments are excel this would need changing depensding on your attachments. End If Next 'Send the email Call message.Send(False) s.ConvertMIME = True ' Restore conversion End Function VBA
但是現(xiàn)實情況是這樣的
我們需要郵件從公郵發(fā)送出去
何謂公郵:整個Team使用的郵箱,如***admin@email.com 之類的郵箱
使用過反人類的 Lotus notes 都知道公郵是需要先打開個人郵箱才能進去的
于是當我把以上的VBA 代碼增加如下代碼,設置從公郵里面發(fā)送郵件后
Server = "C***/****r/****" Path = "****\C*****.nsf" Set db = s.GetDataBase(Server, Path)
郵件確實是從公郵發(fā)送出來,但是很遺憾,郵件發(fā)送人那顯示的是我的個人郵箱,而查看我個人的已發(fā)送郵件,是完全查不到,但是在公郵已發(fā)送郵件可以看到
這就無法理解了,于是開啟了漫長的2天人類大戰(zhàn)反人類Lotus notes戰(zhàn)役
前前后后試過各種VBA代碼【表問為什么不直接調(diào)接口】
但要不就是能顯示為公郵發(fā)送的,但郵件 body 不能Html格式,否則就是相反,總之一句話:二者不可兼得
期間看遍國內(nèi)外關(guān)于Lotus notes VBA的網(wǎng)站
最后,實在是忍不了了,開始搜索Python,C#
一直猶猶豫豫沒有寫是因為同事告訴我,比如使用C#就需要郵箱密碼,而這個東西我們沒有也不會有的
最后的最后,決定賭一把,我先用C#,直接寫出來,等報錯提示密碼沒有的時候我再想辦法
于是戰(zhàn)戰(zhàn)兢兢有了以下代碼
/// <summary> /// 通過notes發(fā)送郵件 /// </summary> /// <param name="mailTo">實時數(shù)據(jù)庫</param> /// <returns></returns> public static void SendForNotes() { string notesPwd = ""; string notesServer = "C***3/C***/***r/***C"; string NotesDBName = @"M**l\C***to.nsf"; string mailTo = "m****o@c**.***.com"; string mailSubject = DateTime.Now.ToString(); string mailBoby = "<html><body><table border='1'><tr><th>Month</th><th>Savings</th></tr><tr><td>January</td><td>$100</td></tr></table></body></html>"; NotesSession ns; NotesDatabase db; NotesDocument doc; try { ns = new NotesSession(); if (ns != null) { //您本機notes的密碼 ns.Initialize(notesPwd); //初始化NotesDatabase db = ns.GetDatabase(notesServer, NotesDBName, false); doc = db.CreateDocument(); doc.ReplaceItemValue("Form", "Memo"); doc.ReplaceItemValue("SendTo", mailTo); doc.ReplaceItemValue("Subject", mailSubject.Replace('\r', ' ').Replace('\n', ' ')); doc.AppendItemValue("Principal", "C******m");//設置郵件的發(fā)件人昵稱 NotesRichTextItem rt = doc.CreateRichTextItem("Body"); var richStyle = ns.CreateRichTextStyle(); richStyle.PassThruHTML = 1; rt.AppendStyle(richStyle); rt.AppendText(mailBoby); //發(fā)送郵件 object obj = doc.GetItemValue("SendTo"); doc.Send(false, ref obj); doc = null; } } catch (Exception ex) { // Log.CreateLog(ex.Message); } finally { ns = null; db = null; doc = null; } }
抱著必死的心態(tài)小心翼翼的點擊了調(diào)試
WTF!!!!
居然收到一封有郵件!沒有密碼??!不需要密碼嗎!密碼不用也能發(fā)送!??!
再試了一次后,發(fā)現(xiàn)真的不需要!??!
因為我們每天開機打開notes的時候也不需要輸入密碼?。?!這可能是和本機的ID文件有綁定?。?!在畢業(yè)后的第一家公司中是需要輸入密碼的!
于是欣喜若狂
開始修改代碼
最終版本
/// <summary> /// 通過notes發(fā)送郵件 /// </summary> /// <param name="mailTo">實時數(shù)據(jù)庫/lysh</param> /// <returns></returns> public static void SendForNotes2() { string notesPwd = ""; string notesServer = "C****3/**/S***/****"; string NotesDBName = @"****\******.nsf"; string mailTo = "****t**@***.com"; string mailSubject = DateTime.Now.ToString(); string mailBoby = "<html><body><table border='1'><tr><th>Month</th><th>Savings</th></tr><tr><td>January</td><td>$100</td></tr></table></body></html>"; NotesSession ns; NotesDatabase db; NotesDocument doc; try { ns = new NotesSession(); if (ns != null) { //您本機notes的密碼 ns.Initialize(notesPwd); //初始化NotesDatabase db = ns.GetDatabase(notesServer, NotesDBName, false); doc = db.CreateDocument(); doc.ReplaceItemValue("Form", "Memo"); doc.ReplaceItemValue("SendTo", mailTo); doc.ReplaceItemValue("Subject", mailSubject.Replace('\r', ' ').Replace('\n', ' ')); doc.SaveMessageOnSend = true; NotesStream HtmlBody = ns.CreateStream(); HtmlBody.WriteText(mailBoby);//構(gòu)建HTML郵件,可以在頭和尾添加公司的logo和系統(tǒng)提醒語 NotesMIMEEntity mine = doc.CreateMIMEEntity("Body");//構(gòu)建郵件正文 mine.SetContentFromText(HtmlBody, "text/html;charset=UTF-8", Domino.MIME_ENCODING.ENC_IDENTITY_BINARY); doc.AppendItemValue("Principal", "C**********am");//設置郵件的發(fā)件人昵稱 //發(fā)送郵件 object obj = doc.GetItemValue("SendTo"); doc.Send(false, ref obj); doc = null; } } catch (Exception ex) { // Log.CreateLog(ex.Message); } finally { ns = null; db = null; doc = null; } }
期間還遇到
由于這句代碼放置的位置不對,導致顯示不正確
doc.AppendItemValue("Principal", "C**********am");//設置郵件的發(fā)件人昵稱
