无法从用户那里获取日历 API 事件

Question

所以我目前可以使用我的社交用户帐户登录，但似乎无法访问该用户的日历 API 事件。 这是一个网络应用，所以下面的代码似乎打开了另一个标签。

流程：登录->主页->日历(localhost:8000/accounts/login-> localhost:8000->localhost:8000/日历)

@login_required
def calendar(request):
    context={}  
    results = get_user_events(request)
    context['results'] = results
    context['nmenu'] = 'calendar'
   

    return render(request, 'home.html', context)

    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(

        # Save the credentials for the next run
        with open('token.json', 'w') as token:
            token.write(creds.to_json())
    try:
        service = build('calendar', 'v3', credentials=creds)

        # Call the Calendar API
        now = datetime.datetime.utcnow().isoformat() + 'Z'  # 'Z' indicates UTC time

        events = events_result.get('items', [])

        if not events:
            print('No upcoming events found.')
            return

        # Prints the start and name of the next 10 events
        for event in events:
            start = event['start'].get('dateTime', event['start'].get('date'))
            print(start, event['summary'])
        return events

    except HttpError as error:
        print('An error occurred: %s' % error)

重定向 URI 未匹配是常见的 oauth 错误。这是您希望将授权返回到的位置。必须在谷歌云控制台注册

根据您发送的错误消息http://localhost:someport/

这必须与您在谷歌云控制台中为您的项目添加的项目之一完全匹配，但您似乎没有列出该项目。

解决方案是从错误消息中获取uri并添加它。请记住，它必须完全匹配，这意味着端口和您的尾随 /。如果您的应用在每次运行时都更改端口，则需要修复它，使其从静态端口运行，以便您可以将其添加为重定向 uri。
