无法从用户获取日历 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。 它是一个网络应用程序，所以下面的代码似乎打开了另一个选项卡。

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)

calendar.py

from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
import os
def get_user_events(request):
    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())
    try:
        service = build('calendar', 'v3', credentials=creds)

        # Call the Calendar API
        now = datetime.datetime.utcnow().isoformat() + 'Z'  # 'Z' indicates UTC time
        print('Getting the upcoming 10 events')
        events_result = service.events().list(calendarId='primary', timeMin=now,
                                              maxResults=10, singleEvents=True,
                                              orderBy='startTime').execute()
        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)
        return []

重定向 URI 不匹配是一个常见的 oauth 错误。这是您希望将授权返回到的位置。它必须在 Google 云控制台

中注册

根据您发送的错误信息http://localhost:someport/

这必须与您在 google 云控制台中为您的项目添加的项目完全匹配，您似乎没有列出。

解决方法是从报错信息中取出uri并添加进去。请记住，它必须完全匹配，这意味着端口和您的尾随 /。如果您的应用程序在您每次运行时都更改端口，您将需要对其进行修复，以便它运行脱离静态端口，以便您可以将其添加为重定向 uri。
