HTTPError：403 客户端错误：禁止通过 Office365-REST-Python-Client 获取 url

Question

我为我的组织尝试了此示例代码（我的 AD 管理员在 SharePoint 中授予了完全访问权限：

from office365.runtime.auth.client_credential import ClientCredential
from office365.sharepoint.client_context import ClientContext

site_url = "https://myname.sharepoint.com"
client_id = "xxx-xxx-xxx-xxx-xxx"
client_secret = "xxxxxxxx"

ctx = ClientContext(site_url).with_credentials(ClientCredential(client_id, client_secret))

folder_path = 'sites/SOF'
root_folder = ctx.web.get_folder_by_server_relative_path(folder_path).expand(["Files"]).get().execute_query()
print("root_folder = ", root_folder)

for file in root_folder.files:
    print(file.name)

但我还是明白

  File "C:\Users\username\AppData\Local\Programs\Python\Python310\lib\site-packages\requests\models.py", line 1021, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://myname.sharepoint.com/_api/Web/getFolderByServerRelativePath(DecodedUrl='sites%2FSOF')?$expand=Files

我什至尝试过

site_url = "https://myname.sharepoint.com/sites/SOF"

但它仍然返回：

requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://myname.sharepoint.com/sites/SOF/_api/Web/getFolderByServerRelativePath(DecodedUrl='')?$expand=Files
