为什么收到“客户端错误：403客户端错误：...错误消息：访问被拒绝请检查凭据，然后重试”

问题描述

我正在尝试从Outlook获取日历数据，所以我有以下代码：

from O365 import Account,MSGraPHProtocol
import datetime as dt

CLIENT_ID = 'f8384621-1095-4519-8999-0c7e616b7bc8'
SECRET_ID = '.s03m-t9u2q_9.Lpim5F.DTL-F1u4MBQy6'

credentials = (CLIENT_ID,SECRET_ID)

protocol = MSGraPHProtocol()
#protocol = MSGraPHProtocol(defualt_resource='<[e-mail]>')
scopes = ['User.Read']
account = Account(credentials,protocol=protocol)

if account.authenticate(scopes=scopes):
   print('Authenticated!')

schedule = account.schedule()
calendar = schedule.get_default_calendar()
events = calendar.get_events(include_recurring=False)
# events = calendar.get_events(query=q,include_recurring=True)


for event in events:
    print(event)

但不幸的是，在成功通过身份验证后，还会出现以下错误：

Client Error: 403 Client Error: Forbidden for url: https://graph.microsoft.com/v1.0/me/calendar | Error Message: Access is denied. Check credentials and try again.
Traceback (most recent call last):

解决方法

您尚未添加访问日历事件的范围。将以下范围添加到您的代码中，然后重试。

protocol = MSGraphProtocol()    
scopes = ['User.Read'] 
calendar_scopes = protocol.get_scopes_for('calendar_all')
scopes.extend(calendar_scopes)
account = Account(credentials,protocol=protocol)

if account.authenticate(scopes=scopes):
    print('Authenticated!')
