from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.files.file import File
app_settings = {
'url': 'https://YOURtenant.sharepoint.com/sites/somesite/',
'client_id': '12344-abcd-efgh-1234-1a2d12a21a2121a',
'client_secret': 'Oamytacohungry234343224534543=',
}
context_auth = AuthenticationContext(url=app_settings['url'])
context_auth.acquire_token_for_app(client_id=app_settings['client_id'], client_secret=app_settings['client_secret'])
ctx = ClientContext(app_settings['url'], context_auth)
web = ctx.web
ctx.load(web)
ctx.execute_query()
response = File.open_binary(ctx, "/Shared Documents/Invoice.pdf")
with open("./Invoice.pdf", "wb") as local_file:
local_file.write(response.content)
If the above script does not work, take a step back and make sure you are connected to the site.
