python-3.x - 使用 Python 从 Microsoft Teams 抓取文件

Question

Teams 似乎缺乏将文件镜像到共享目录的任何 native 方式。我正在尝试使用 Python(或其他语言，但首选 Python!):

一种。直接从微软团队拉入内存使用 Python 与 Pandas 一起处理

湾将团队中的文件复制到共享网络文件夹中(然后 Python 可以读入)

我发现了这个，但无法让它与团队一起工作 - 团队 URL 看起来不像这些。 How to read SharePoint Online (Office365) Excel files in Python with Work or School Account?

不过，这似乎接近我想做的事情。我还在 PyPi 存储库中找到了“pymsteams”。 https://pypi.org/project/pymsteams/这似乎只是让您向 Teams 发送消息而没有其他功能？除非我误解了什么。

from office365.runtime.auth.authentication_context
import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.file import File 

url = 'https://teams.microsoft.com/l/file'
username = 'myusername'
password = 'mypassword'
relative_url ='myurl'

ctx_auth = AuthenticationContext(url)
ctx_auth.acquire_token_for_user(username, password)

尝试运行上面的代码给出
AttributeError: 'NoneType' 对象没有属性 'text'

Answer 1

我已设法使用您链接的 Office-365-REST-Python-Client 使其工作。
如果您使用的是 SharePoint Online，则需要获取 App-Only principle使用acquire_token_for_app 函数而不是acquire_token_for_user 来设置和连接，然后传递一个client_id 和client_secret 而不是用户名和密码。

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.file import File

client_id = 'yourclientid'
client_secret = 'yourclientsecret'
url = 'https://yoursharepointsite.com/teams/yourteam'
relative_url = '/teams/yourteam/Shared%20Documents/yourteamschannel/yourdoc.extension'
  
ctx_auth = AuthenticationContext(url)
if ctx_auth.acquire_token_for_app(client_id, client_secret):
    ctx = ClientContext(url, ctx_auth)
    with open(filename, 'wb') as output_file:
        response = File.open_binary(ctx, relative_url)
        output_file.write(response.content) 
else:
    print(ctx_auth.get_last_error())

这应该将您的文件下载到本地驱动器(通过文件名变量指定)，然后您可以加载到 Pandas 等中进行处理
