如何将PDF文件上传到SharePoint网站？

Question

如何使用Python请求将PDF文件上传到SharePoint网站？这就是我到目前为止所做的：

import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning

requests.packages.urllib3.disable_warnings(InsecureRequestWarning)

sessionObj = requests.session()
url1 = 'https://globalconsumer.collaborationtools.consumer.citigroup.net/sites'
sessionObj.auth = ('username', 'password')

r = sessionObj.post(url1, auth=sessionObj.auth, verify=False)

print("LOGIN RESPONSE: " + format(r.status_code))
print(r.url)
