我通過VBA中的Gmail REST API發送HTML電子郵件,並且HTML圖像未顯示在發送的消息中。我添加了一個img標題標籤,我試過了一個經過批准的「ci3.googleusercontent.com」版本的圖片來源,試過了png & jpg。由於我在POST請求的正文中發送電子郵件信息,因此我不認爲我需要使用Base64。沒有任何空格,因此不必擔心%20並轉換爲+。HTML圖像沒有顯示在VBA中通過Gmail API發送的MIME消息中,使用3D
還有其他想法嗎?
Sub SendGmail()
Dim result As String, myURL As String, postData As String
Dim winHttpReq As Object
Dim x As Integer
Set winHttpReq = CreateObject("WinHttp.WinHttpRequest.5.1")
myURL = "https://www.googleapis.com/upload/gmail/v1/users/me/messages/send"
postData = "From: 'Michael F' <[email protected]>" & vbCr & _
"Subject: Test Message " & Now() & vbCr & _
"Reply-To: [email protected]" & vbCr & _
"To: [email protected]" & vbCr & _
"Content-Type: text/html; charset=utf-8" & vbCr & _
"Content-Transfer-Encoding: quoted-printable" & vbCr & vbCr & _
"<b>Test Message</b><p>" & vbCr & vbCr & _
"<img alt='ExampleLogo' " & _
"title='ExampleLogo' src='http://www.example.com/LogoSignature.png'>"
'*Putting 3D right after src= solved the problem!*
winHttpReq.Open "POST", myURL, False
winHttpReq.SetRequestHeader "Host", "www.googleapis.com"
winHttpReq.SetRequestHeader "Content-Length", Len(postData)
winHttpReq.SetRequestHeader "Content-Type", "message/rfc822"
winHttpReq.SetRequestHeader "Authorization", "Bearer <mycode>"
winHttpReq.Send (postData)
Set winHttpReq = Nothing
End Sub
這裏是的摘錄收到電子郵件HTML源代碼。在我發送文件夾發送的電子郵件不顯示中的圖像,但HTML是有這也是奇怪...
