使用Shareplum向SharePoint上传文件出现X-RequestDigest键错误如何解决

你获取X-RequestDigest的逻辑完全错误：你发起的第一个POST请求本身是文件上传请求，该请求要求请求头携带合法的X-RequestDigest才能执行成功，但你此时填的是占位字符串FormDigestValue，这个请求必然执行失败，失败响应的头里自然不存在X-RequestDigest字段，触发KeyError。

• 调用SharePoint专门的contextinfo接口获取合法的X-RequestDigest，不要通过上传请求拿
• 修正文档库路径的URL编码问题，Shared%20Documents要改为原始字符串Shared Documents，否则接口会识别不到路径
• 修正状态码判断逻辑，response.status_code是整数类型，不要和字符串'200'做比对

import requests
from shareplum import Office365

# Set Login Info
username = 'my.email@address.com'
password = 'myverifiedapppassword'
site_name = 'mysite'
base_path = 'https://xxxxxxxx.sharepoint.com'
site_path = base_path + "/sites/" + site_name
doc_library = 'Shared Documents'
file_name = "hellotest.txt"

# Obtain auth cookie
authcookie = Office365(base_path, username=username, password=password).GetCookies()
session = requests.Session()
session.cookies = authcookie
session.headers.update({'user-agent': 'python_bite/v1'})
session.headers.update({'accept': 'application/json;odata=verbose'})

# 正确获取X-RequestDigest的逻辑
digest_resp = session.post(f"{site_path}/_api/contextinfo")
digest_value = digest_resp.json()['d']['GetContextWebInformation']['FormDigestValue']
session.headers.update({'X-RequestDigest': digest_value})

# Upload file
with open(file_name, 'rb') as file_input:
    try:
        response = session.post(
            url=f"{site_path}/_api/web/GetFolderByServerRelativeUrl('{doc_library}')/Files/add(url='{file_name}',overwrite=true)",
            data=file_input)
        print("response: ", response.status_code)
        if response.status_code == 200:
            print("File uploaded successfully")
    except Exception as err:
        print("Something went wrong: " + str(err))
