python 中的逻辑解析重复事件

Question

我对 python 和 icalendar 非常陌生，但我正在尝试从 Apple 的 Icloud 网站获取我的 icalendar，然后能够访问日历信息，以便我可以在应用程序上显示它。我能够从日历中获取任何不会重复发生的事件，但它只会获取这些事件并且出于某种原因会跳过重复发生的事件（这基本上是我现在安排的唯一事件类型）这是代码我目前拥有的关于如何获得重复事件的任何想法？

from icalendar import Calendar, Event
import urllib.request

def getCalendar():
    urlHome = urllib.request.urlopen('https://p10-calendarws.icloud.com/ca/subscribe/1/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX').read()

    return urlHome

def displayCalendar(calendar):

    showCalHome = Calendar.from_ical(calHome)
    for event in showCalHome.walk('VEVENT'):
        date = event.get('dtstart').dt
        summary = event.get('summary')
        print(summary,date)


calendar = getCalendar()
displayCalendar(calendar)

关于我可以做些什么不仅可以获取单个事件的列表，还可以获取重复发生的事件的列表，有什么想法或想法吗？

通过解析 ICS 文件本身，将大量值转换为字符串，然后将字符串与我要查找的内容进行比较，结果如下所示：

import json
import requests
from icalendar import Calendar, Event
import urllib.request
from datetime import *
import datetime
from dateutil.rrule import *


def getCalendar():
    urlWork = urllib.request.urlopen('https://p10-calendarws.icloud.com/ca/subscribe/1/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX').read()
    urlHome = urllib.request.urlopen('https://p10-calendarws.icloud.com/ca/subscribe/1/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX').read()

    calendars = [urlHome, urlWork]

    return calendars

def getTodaysEvents(calendars):

    calHome = calendars[0]
    calWork = calendars[1]

    allEvents = []
    singleEvents = {}
    homeEvents = {}
    workEvents = {}

    today = str(date.today())
    year = today[0:4]
    month = today[5:7]
    day = today[8:10]
    currentDay = year + month + day

    showCalHome = Calendar.from_ical(calHome)
    for component in showCalHome.walk():
        if component.name == "VEVENT":
            rule = component.get('rrule')
            eventDay = str(component.get('dtstart').dt)
            if rule is not None:
                rrule = dict(rule)
                if 'UNTIL' in rrule.keys():
                    eventEnd = str(rrule['UNTIL'][0])

                        allEvents.append(homeEvents)
                # else: (NEED TO IMPLEMENT WEEKLY EVENTS THAT DON'T END and Events that aren't Reoccuring)

我创建了一个 library，因为我正在寻找完全相同的 use-case。

在您的情况下，recurring-ical-events 可以像这样嵌入：

events = recurring_ical_events.of(calendar).between(start_date, end_date)
for event in events:
    # ...
