我正在嘗試使用 Oauth 2.0 登錄 Google Colab 筆記本，但啟動(dòng)的 Google 登錄網(wǎng)頁(yè)以不存在的 web 結(jié)束(http://localhost:8090/?code=4/NAFDWUxkOxp3FIlB9I_vxFTFm-zjAx0XJpEspQ9dGozG-0L3ccthFD12FAhq_B5hLWTxDFuUg_SjC011V9jiLDw&scope=https://www.googleapis.com/auth/admin.directory.group.member%20https://www.googleapis.com/auth/admin.directory.group%20https://www.googleapis.com/auth/apps.groups.settings)。也許該錯(cuò)誤與任何回調(diào) url 有關(guān)，但我不知道如何解決。這是我用于登錄的代碼。import osos.environ['USE_NATIVE_IPYTHON_SYSTEM_COMMANDS'] = '1'import httplib2from oauth2client.client import flow_from_clientsecretsfrom oauth2client.file import Storagefrom oauth2client.tools import run_flowfrom oauth2client import toolsfrom google.colab import drive; drive.mount('/content/drive')PATH_BASE = '/content/drive/My Drive/.../'CLIENT_SECRET = PATH_BASE + 'client_secret_event.json'SCOPES = [ "https://www.googleapis.com/auth/admin.directory.group", "https://www.googleapis.com/auth/admin.directory.group.member", "https://www.googleapis.com/auth/apps.groups.settings"]STORAGE = Storage(PATH_BASE + 'credentials.storage')flags = tools.argparser.parse_args([])# Start the OAuth flow to retrieve credentialsdef authorize_credentials(): # Fetch credentials from storage credentials = STORAGE.get() # If the credentials doesn't exist in the storage location then run the flow if credentials is None or credentials.invalid: flow = flow_from_clientsecrets(CLIENT_SECRET, scope=SCOPES) http = httplib2.Http() credentials = run_flow(flow, STORAGE, flags, http=http) return credentialscredentials = authorize_credentials()關(guān)于為什么會(huì)發(fā)生這種情況的任何想法？

您將希望使用已安裝的應(yīng)用程序流而不是 Web 應(yīng)用程序流。
原因是 Colab 后端沒(méi)有直接暴露給 Internet，因此無(wú)法處理基于 Web 的 OAuth 流常見(jiàn)的 URL 重定向。

按照評(píng)論和本教程（您可以從中受益以在控制臺(tái)中創(chuàng)建應(yīng)用程序），我實(shí)現(xiàn)了以下代碼：
creds = None
# Check if previous log-in exists
if os.path.exists('/content/drive/MyDrive/Projects/xyz/token.pickle'):
with open('/content/drive/MyDrive/Projects/xyz/token.pickle', 'rb') as token:
creds = pickle.load(token)
# If not available or invalid, log in using the "console" InstalledAppFlow
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('/content/drive/MyDrive/Projects/xyz/credentials.json', SCOPES)
creds = flow.run_console()
# Save the access token in token.pickle file for the next run
with open('/content/drive/MyDrive/Projects/xyz/token.pickle', 'wb') as token:
pickle.dump(creds, token)
# Connect to the Gmail API
service = build('gmail', 'v1', credentials=creds)
