将 binary/base64 数据设置为 VB 脚本中的附件 CDO.Message
Set binary/base64 data as attachment in VB Script CDO.Message
我正在尝试发送带有 PDF 附件的电子邮件。我在 binary/Base64 中有我的附件数据,但是当我尝试将其写入流时,它不起作用。这是我的代码。我正在使用从这里上传 class - http://www.codeguru.com/csharp/.net/net_asp/article.php/c19297/Pure-ASP-File-Upload.htm

' Loop through the uploaded files

Response.Write "Error: " & Err.Number
Response.Write "Error (Hex): " & Hex(Err.Number)
Response.Write "Source: " & Err.Source
Response.Write "Description: " & Err.Description
End If
我收到以下错误。我不知道我哪里错了。
ADODB.StreamDescription: Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.
有人可以帮忙吗?
终于,我成功了。感谢 kul-tigin 指出 vbArray + vbByte
的问题。上传的数据是多字节数据,需要归一化。
下面是我得到的函数here,用于转换多字节数组。
Function GetFileDataBinary()
Dim RS, LMultiByte, Binary
Const adLongVarBinary = 205
Set RS = CreateObject("ADODB.Recordset")
LMultiByte = LenB(FileData)
If LMultiByte > 0 Then
RS.Fields.Append "mBinary", adLongVarBinary, LMultiByte
RS.Open
RS.AddNew
RS("mBinary").AppendChunk FileData & ChrB(0)
RS.Update
Binary = RS("mBinary").GetChunk(LMultiByte)
End If
GetFileDataBinary = Binary
End Function
我像下面这样更改了我的代码,但它运行得似乎很糟糕。
Dim uploadFileName
Dim uploadFileData
' Check if any files were uploaded
If Uploader.Files.Count > 0 Then
' Loop through the uploaded files
For Each File In Uploader.Files.Items
uploadFileName = File.FileName
uploadFileData = File.GetFileDataBinary
Next
End If
我可以调用 File.GetFileDataBinary
因为我把我的 GetFileDataBinary
放在了我的 upload.asp
.
