使用服务帐户时的Google Calendar API HttpError 404

问题描述

我正在尝试从服务帐户获取日历中的事件列表,以便不必验证自己的身份即可显示日历。当我运行以下代码时,出现404错误

ScopES = ['https://www.googleapis.com/auth/calendar.readonly']
    SERVICE_ACCOUNT_FILE = os.path.join(os.path.dirname(
        os.path.realpath(__file__)),'static/calendarSync/service-account.json')

    calId = "blakewright1021@gmail.com"

    credentials = service_account.Credentials.from_service_account_file(
        SERVICE_ACCOUNT_FILE,scopes=ScopES)


    google_account = googleapiclient.discovery.build(
        'calendar','v3',credentials=credentials)

    cal_list = google_account.calendarList()  # pylint: disable=no-member

    #page_token = None

    #calendar_list = cal_list.list(pagetoken=page_token).execute()
    # for calendar_list_entry in calendar_list['items']:
    #   print("Here: ")
    #    print(calendar_list_entry['summary'])

    calendar = cal_list.get(
        calendarId=calId)
    output = calendar.execute()['summary']

当我使用注释掉的代码尝试打印日历列表时,它不会打印任何内容,因此该列表必须为空。

这是回溯:

googleapiclient.errors.HttpError: <HttpError 404 when requesting https://www.googleapis.com/calendar/v3/users/me/calendarList/blakewright1021%40gmail.com?alt=json returned "Not Found">

我已与服务帐户共享日历。在没有服务帐户的情况下进行身份验证时,我也可以访问日历。我在做什么错了?

解决方法

CalendarList是Google日历网络应用程序左下方的列表。

除非您使用clanedarlist.insert将日历插入到服务帐户日历列表中,否则日历不会显示在该列表中。

与服务帐户共享日历后,只需在您共享的日历ID上做一个calendar.get,便可以访问它。然后,如果您确实需要在日历列表中,可以执行一个calendarlist.insert。
