Python Sharepoint API 身份验证成功但无法读取 Excel 文件

问题描述

所以基本上对我的共享点的身份验证是成功的,但是 Pandas 无法读取 xlsx 文件(存储为字节对象)。

我收到错误: “ValueError:文件不是可识别的excel文件

代码

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.files.file import File 
import io
import pandas as pd

#target url taken from sharepoint and credentials
url = 'https://**[company-name]**-my.sharepoint.com/:x:/p/**[email-prefix]**/EYSZCv_Su0tBkarOa5ggMfsB-5DAB-FY8a0-IKukCIaPOw?e=iW2K6r' # this is just the link you get when clicking "copy link" on sharepoint
username = '...'
password = '...'


ctx_auth = AuthenticationContext(url)
if ctx_auth.acquire_token_for_user(username,password):
  ctx = ClientContext(url,ctx_auth)
  web = ctx.web
  ctx.load(web)
  ctx.execute_query()
  print("Authentication successful")

response = File.open_binary(ctx,url)
#save data to BytesIO stream
bytes_file_obj = io.BytesIO()
bytes_file_obj.write(response.content)
bytes_file_obj.seek(0) #set file object to start

#read excel file and each sheet into pandas dataframe 
df = pd.read_excel(bytes_file_obj)
df

对这里可能出现的问题有什么想法吗?

解决方法

我也遇到了同样的错误(&到达了这个页面)。

我可以解决这个问题,改变网址链接。
使用文件路径(从打开的 excel 文件的“复制路径”中获得),也许它会起作用...

示例:

url = 'https://**[company-name]**-my.sharepoint.com/personal/**[email-prefix]**/Documents/filename.xlsx?web=1'
