Question

我有一个文件，我希望使用python以json数组格式读取。我发现有一个名为icalendar 3.11的软件包，但它并没有将iCalendar文本转换为json数组格式。

请参阅下面的icalendar文字：

BEGIN:VCALENDAR
PRODID;X-RICAL-TZSOURCE=TZINFO:-//Airbnb Inc//Hosting Calendar 0.8.8//EN
CALSCALE:GREGORIAN
VERSION:2.0
BEGIN:VEVENT

END:VCALENDAR

利用iCalendar Package here，我尝试了以下内容：

from icalendar import Calendar

result = Calendar().from_ical(ical_content)

结果

VCALENDAR({u'CALSCALE': vText('GREGORIAN'), u'VERSION': vText('2.0'), u'PRODID': vText('-//Airbnb Inc//Hosting Calendar 0.8.8//EN')}, VEVENT({u'LOCATION': vText('Rittenhouse Square Cozy Studio Apartment'), u'DESCRIPTION': vText('CHECKIN: 11/10/2016\nCHECKOUT: 11/11/2016\nNIGHTS: 1\nPHONE: +1 (111) 111-1111\nEMAIL: gregory-66i5v1thmkdva1u4@test.bnb.com\nPROPERTY: Rittenhouse Square Cozy Studio Apartment\n'), u'UID': vText('-4sxkntmd7ehk-4ybn124l9iwr@bnbhome.com'), u'DTEND': <icalendar.prop.vDDDTypes object at 0x1041e5610>, u'DTSTART': <icalendar.prop.vDDDTypes object at 0x1041e58d0>, u'SUMMARY': vText('John Smith (XXXXXX)')}),VEVENT({u'LOCATION': vText('Rittenhouse Square Cozy Studio Apartment'), u'DESCRIPTION': vText('CHECKIN: 01/02/2017\nCHECKOUT: 01/04/2017\nNIGHTS: 2\nPHONE: +1 (222) 222-2222\nEMAIL: darren-3rntph9q5fqzbao2@test.bnb.com\nPROPERTY: Rittenhouse Square Cozy Studio Apartment\n'), u'UID': vText('-4sxkntmd7ehk-wps9gpnpzxkj@bnbhome.com'), u'DTEND': <icalendar.prop.vDDDTypes object at 0x10441c690>, u'DTSTART': <icalendar.prop.vDDDTypes object at 0x10441c6d0>, u'SUMMARY': vText('Abe Lincoln (XXXXXX)')}))

如何将此icalendar文本转换为json数组？

非常讨厌的方式，但做的工作：

ical_content = """
BEGIN:VCALENDAR
PRODID;X-RICAL-TZSOURCE=TZINFO:-//Airbnb Inc//Hosting Calendar 0.8.8//EN

"""

import icalendar
from icalendar import Calendar

result = Calendar().from_ical(ical_content)

import json

r = []
for key, value in result.property_items():
    inner_d = {}
    if isinstance(value, icalendar.prop.vDDDTypes):
        inner_d[key] = value.dt.isoformat()
    else:
        inner_d[key] = value
    r.append(inner_d)

u = json.dumps(r, indent=4)
print(u)

输出是：
