如何使用 REST API 和 .Net (C# /VB) 下载 LiveLink (OpenText) 文件

Question

使用 LiveLink Server 16.2.9 (2019-06)，内部版本 851

这是我用来下载名为 Active_Time.xlsx 的 LiveLink 文件的代码。如果我在浏览器中粘贴下面的 link，则会下载该文件。但是，当使用此代码时，结果是一个小 XML 文件（见底部）

Dim remoteUri As String = "https://OurServer.com/livelink/livelink.exe?func=ll&objId=33100345&objAction=download"

Using client = New Net.WebClient()
      client.Credentials = New Net.NetworkCredential(username, password, domain)
      client.DownloadFile(remoteUri, "C:\temp\Active_Time.xlsx)           
      Console.WriteLine("File extracted.")
      client.Dispose()
    End Using

已下载某些内容，但不是我预期的 Excel 文件。这是我用记事本编辑文件时得到的结果。

您似乎未通过身份验证？你应该使用其余的 api.
