访问事件的范围不正确

Question

HttpError at /calendar <HttpError 403 when requesting https://www.googleapis.com/calendar/v3/calendars/primary/events?singleEvents=true&orderBy=startTime&alt=json returned "Request had insufficient authentication scopes.". Details: "[{'message': 'Insufficient Permission', 'domain': 'global', 'reason': 'insufficientPermissions'}]"> Request Method: GET Request URL: http://localhost:8000/calendar Django Version: 3.2.9 Exception Type: HttpError Exception Value:

过一会儿再做这个

RefreshError at /calendar The credentials do not contain the necessary fields need to refresh the access token. You must specify refresh_token, token_uri, client_id, and client_secret.

我似乎在访问日历时没有正确的范围，目前看来 access_token 确实出现了。

from google.oauth2.credentials import Credentials
def get_user_events(request):
    credentials = Credentials(get_access_token(request), scopes=SCOPES)
    service = googleapiclient.discovery.build('calendar', 'v3', credentials=credentials)
    google_calendar_events = service.events().list(calendarId='primary', singleEvents=True,
                                          orderBy='startTime').execute()
    google_calendar_events = google_calendar_events.get('items', [])
    return google_calendar_events

def get_access_token(request): 
    social = request.user.social_auth.get(provider='google-oauth2') 
    return social.extra_data['access_token']

所以我使用的范围如下

SCOPES = ['https://www.googleapis.com/auth/calendar']

Answer 1

"Request had insufficient authentication scopes.".

如果我们查看 events.get 的文档，我们会发现此方法对私有用户数据进行操作，这意味着我们需要获得授权才能访问它。最重要的是，我们需要获得以下范围之一的授权

我无法从您的代码中看出您请求的范围。要做的第一件事是确保您在授权用户时请求上述范围之一。如果您更改范围，请记住您必须再次请求用户同意才能生效。

You must specify refresh_token, token_uri, client_id, and client_secret.

听起来您没有正确存储刷新令牌。 get_access_token 如果没有存储刷新令牌，将无法工作。

在官方示例中，请注意他们如何将用户凭据存储在 token.json 中，然后库将在需要时自动请求新的访问令牌。

 """Shows basic usage of the Google Calendar API.
    Prints the start and name of the next 10 events on the user's calendar.
    """
    creds = None
    # The file token.json stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.json'):
        creds = Credentials.from_authorized_user_file('token.json', SCOPES)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.json', 'w') as token:
            token.write(creds.to_json())

访问事件的范围不正确

Not correct scope for accessing events

django

google-calendar-api

google-oauth

python-social-auth
