使用IronPython脚本从Sharepoint将xlsx或csv文件加载到Spotfire中

Question

if I try to load the data using below script, the html code is being loaded instead of proper data. The given link leads to the direct source of xlsx or csv file (if you run that link in the browser, the xlsx or csv file will start downloading automatically). I would be glad to hear why this kind of situation happens and how to love this problem.

import clr
clr.AddReference('System.Net')
from System.Net import HttpWebRequest, NetworkCredential
from Spotfire.Dxp.Data.Import import TextFileDataSource, TextDataReaderSettings

readerSettings = TextDataReaderSettings()
readerSettings.Separator = ";"
readerSettings.CultureName = "en-GB"

req = HttpWebRequest.Create("some link to xlsx file")

user_agent = 'individual user-agent'
req.UserAgent = user_agent
req.Method = "GET"

req.UseDefaultCredentials = True
#req.PreAuthenticate = True
user = Document.Properties["Username"]
password = Document.Properties["Password"]

req.Credentials = NetworkCredential(user, password)

rsp = req.GetResponse()
dSource = TextFileDataSource(rsp.GetResponseStream(),readerSettings)
rsp.Close()

dataManager = Document.Data
dataTable = dataManager.Tables[document.Name]
dataTable.ReplaceData(dSource)

Answer 1

the important part of the HTML returned isn't "Javascript is disabled", it's " We can't sign you in because Javascript is disabled." based on this it sounds like your issue is that you haven't properly authenticated your session.

I would try to validate by loading this code into the Python IDE of your choice and try it independent of Spotfire.

the correct way to access Sharepoint, most likely, is through the Sharepoint API. I don't have experience with this but I'm sure some googling could turn up a solution. once you have a (third-party library free!) solution working in Python, you can adapt it to Spotfire without too much trouble.
