opentext - How to download a LiveLink (OpenText) file using REST API and .Net (C# /VB)

问题描述

Using LiveLink Server 16.2.9 (2019-06), build 851

This is the code I use to download a LiveLink file named Active_Time.xlsx. If I paste the link below in the browser, then the file is downloaded. However, when using this code the result is a small XML file (see bottom)

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

Something is downloaded but not the Excel file I expected. This is what I get if I edit the file with Notepad.

解决方案

看起来你没有通过身份验证？您应该使用其余的 api。
