通过 Raspberry Pi 上的 caldav 使用 python 读取 owncloud 日历

Question

概览
我的目标是开发一个在 Raspberry Pi 上运行的 Python 应用程序，它可以通过网络读取 OwnCloud 日历条目。日历本身是 Owncloud 本地安装的一部分，它驻留在同一本地网络中的另一个 Raspberry Pi 上。进行请求时通过 HTTPS 进行访问，无需主动 SSL 身份验证。

问题
我尝试使用 caldav Python 包。使用 PIP 和 Python v2.7 安装包后，我得到一个 Exception: The CalDAV server you are using has a problem with path handling.

这是我在 PYTHON IDLE v2.7 中输入的内容：

import caldav  
cal_user='user'  
cal_pass='pass'  
cal_url='https://192.168.1.46/remote.php/caldav/calendars/user/pers%C3%B6nlich'  
cal_client=caldav.DAVClient(cal_url, username='user', password='pass', ssl_verify_cert=False)  
cal_principal=cal_client.principal()

这就是控制台上打印的内容：

raise Exception("The CalDAV server you are using has "

Exception: The CalDAV server you are using has a problem with path handling.

我已尝试尽可能多地使用 URL 以消除任何可能的输入错误，但我仍然不能 100% 确定我是否做到了。

有人对我的案例中的最终异常消息有实际的解释吗？我可以在哪里继续寻找解决问题的方法？

Answer 1

我能够重现您的问题。解决方案是从

更改 URL 中的日历名称

pers%C3%B6nlich 到 pers%c3%b6nlich

注意B 和C 的情况。
