我正在寻找一种编程方式，将每个 Microsoft Teams 频道的所有聊天消息（文本和图像内容）导出到 word 或 pdf 文档（任何支持文本和消息的输出介质）。我需要能够做到这一点，而无需向公司全局管理员寻求特定角色的许可。我已经研究了不同的方法，例如 Graph API（azure 应用程序注册）、电子发现以及从隐藏的 Outlook 文件夹中提取此信息。这些方法的共同主题是，我们需要针对导出策略中的特定需求寻求 IT 管理员的许可。
到目前为止，我已经尝试使用 Microsoft Teams 的 Web 应用程序版本并使用网页抓取方法，我已经能够循环浏览每个渠道中的消息并将其导出到 Word 文档中。我想知道是否有一种更优雅、更好、更不容易出错的方法。
寻找一些建议。
这是一个名义上的解决方案。诚然，它不是很好/完整。但它在某种程度上确实有效。
你激励我清理我的尝试并发布它：
https://github.com/poleguy/selenium_teams
仅在 ubuntu 20.04 上测试。
克隆存储库。
运行 ./setup_python 以获取 conda 环境。
编辑脚本以指定您的网址/登录名。
运行 python ./selenium_teams.py
在弹出的浏览器中手动登录。
转到您想要聊天的聊天室。单击“输入新消息”部分。
按 Enter 键让 python 继续。
这将开始将所有消息保存到文本文件中。
获得文本文件后，将其转换为 pdf 或 word。
（不完整：无法处理图像，运行速度非常慢，可能会耗尽内存......测试很少。）
我的这个 Javascript 脚本肯定可以优化，但它确实有效。 要使用它，您应该直接在 https://teams.microsoft.com 网站上浏览到您选择的团队对话。 将脚本放入开发人员工具的控制台窗格中，检查聊天窗格中的至少一个元素，然后运行脚本。
不用说，聊天记录越长，完成该过程所需的时间就越长。通过这个脚本，我已经成功地将多个聊天记录传输到 PDF。

For this script to work you must be viewing Teams from your browser.
https://teams.microsoft.com
This script was tested in Firefox.
You must be using Developer tools of your browser
YOU MUST INSPECT a message, otherwise the HTML elements will not be available
The elements are burried in an iFrame, and you must inspect something for the iFrame code to be available to the script
Once you have inspected something, go to the Console tab of your developer tools
paste this whole script and run it
You can run it by pressing the Play button,
or with the keyboard shortcut Ctrl + Enter
It will first scroll all the way to the first message
Then it will create a new browser window with the messages in it
Then it is up to you to do what you want with it
I suggest you print the content to pdf (Ctrl + P)
It is possible the process will stop before reaching the top
If that is the case and you want to keep scrolling,
you can retrigger the script but call it with a false parameter to maintain the existing storage list
