vba의 CDO를 통해 Gmail받은 편지함 메일 메시지를 가져 오는 중 Excel

Question

VBA에서 CDO를 사용하여 Gmail 계정의받은 편지함에 액세스하고 싶습니다. 나는 이미 메일 메시지를 보내 왔지만받은 편지함 메시지를 Excel 시트로 가져 오는 방법을 모릅니다. 가능하면 각 메시지의 태그를 식별 할 수 있기를 바랍니다.

Answer 1

특히 CDO를 묻는 질문이 있지만 this similar SO question에서 CDO로 직접 가능하지는 않습니다.

받은 편지함 메일 메시지를 가져 오는 다른 방법으로 Google은 최근 Excel에서 사용할 수있는 Gmail API를 출시했습니다. 다음은 VBA-Web을 사용한 예입니다.

' Setup client and authenticator (cached between requests) 
Private pGmailClient As WebClient 
Private Property Get GmailClient() As WebClient 
    If pGmailClient Is Nothing Then 
     ' Create client with base url that is appended to all requests 
     Set pGmailClient = New WebClient 
     pGmailClient.BaseUrl = "https://www.googleapis.com/gmail/v1/" 

     ' Use the pre-made GoogleAuthenticator found in authenticators/ folder 
     ' - Automatically uses Google's OAuth approach including login screen 
     ' - Get API client id and secret from https://console.developers.google.com/ 
     ' - https://github.com/timhall/Excel-REST/wiki/Google-APIs for more info 
     Dim Auth As New GoogleAuthenticator 
     Auth.Setup "Your client id", "Your client secret" 
     Auth.AddScope "https://www.googleapis.com/auth/gmail.readonly" 
     Auth.Login 
     Set pGmailClient.Authenticator = Auth 
    End If 

    Set GmailClient = pGmailClient 
End Property 

' Load messages for inbox 
Function LoadInbox() As Collection 
    Set LoadInbox = New Collection 

    ' Create inbox request with userId and querystring for inbox label 
    Dim Request As New WebRequest 
    Request.Resource = "users/{userId}/messages" 
    Request.AddUrlSegment "userId", "me" 
    Request.AddQuerystringParam "q", "label:inbox" 

    Dim Response As WebResponse 
    Set Response = GmailClient.Execute(Request) 

    If Response.StatusCode = WebStatusCode.Ok Then 
     Dim MessageInfo As Dictionary 
     Dim Message As Dictionary 

     For Each MessageInfo In Response.Data("messages") 
      ' Load full messages for each id 
      Set Message = LoadMessage(MessageInfo("id")) 
      If Not Message Is Nothing Then 
       LoadInbox.Add Message 
      End If 
     Next MessageInfo 
    End If 
End Function 

' Load message details 
Function LoadMessage(MessageId As String) As Dictionary 
    Dim Request As New WebRequest 
    Request.Resource = "users/{userId}/messages/{messageId}" 
    Request.AddUrlSegment "userId", "me" 
    Request.AddUrlSegment "messageId", MessageId 

    Dim Response As WebResponse 
    Set Response = GmailClient.Execute(Request) 

    If Response.StatusCode = WebStatusCode.Ok Then 
     Set LoadMessage = New Dictionary 

     ' Pull out relevant parts of message (from, to, and subject from headers) 
     LoadMessage.Add "snippet", Response.Data("snippet") 

     Dim Header As Dictionary 
     For Each Header In Response.Data("payload")("headers") 
      Select Case Header("name") 
      Case "From" 
       LoadMessage.Add "from", Header("value") 
      Case "To" 
       LoadMessage.Add "to", Header("value") 
      Case "Subject" 
       LoadMessage.Add "subject", Header("value") 
      End Select 
     Next Header 
    End If 
End Function 

Sub Test() 
    Dim Message As Dictionary 
    For Each Message In LoadInbox 
     Debug.Print "From: " & Message("from") & ", Subject: " & Message("subject") 
     Debug.Print Message("snippet") & vbNewLine 
    Next Message 
End Sub 

을 사용하는 예입니다.
