使用python中的openpyxl读取存储在sharepoint位置的xlsx？

快一点.

我有一个位于sharepoint驱动器上的XLSX文件,无法在python中使用openpyxl打开它,如果它存储在我的本地驱动器上,它可以正常工作.

我试过这个.

from openpyxl import load_workbook
wb = load_workbook('https://content.potatocompany.com/workspaces/PotatoTeam/Shared Documents/XYZ errors/XYZ Errors_Confirm.xlsx')

抛出此异常:

C:\Anaconda\lib\site-packages\openpyxl\reader\excel.py in load_workbook(filename, use_iterators, keep_vba, guess_types, data_only)
    123     except (BadZipfile, RuntimeError, IOError, ValueError):
    124         e = exc_info()[1]
--> 125         raise InvalidFileException(unicode(e))
    126     wb = Workbook(guess_types=guess_types, data_only=data_only)
    127 

InvalidFileException: [Errno 22] invalid mode ('rb') or filename: 'https://...

我错过了什么吗？我需要阅读python中其中一个工作表的内容.

编辑:

使用crussell的建议,我收到401 UNAUTHORIZED :

import requests
import urllib
from openpyxl import load_workbook
from requests.auth import HTTPBasicAuth

file = "https://content.potatocompany.com/workspaces/PotatoTeam/Shared Documents/XYZ errors/XYZ Errors_Confirm.xlsx"

username = 'PotatoUser'
password = 'PotatoPassword'

resp=requests.get(file, auth=HTTPBasicAuth(username, password))
print(resp.content)

似乎sharepoint和请求不兼容,包括摘要式身份验证和基本身份验证 http://docs.python-requests.org/en/latest/user/authentication/
