Google Drive API OAuth 2.0：ERR_CONNECTION_REFUSED

Question

我在我的个人 GCP 中启用了 Google Drive API，设置了我的 OAuth2 同意屏幕，并下载了我的 credentials.json 文件。我现在从 Colab 中的 Python quickstart 运行这段代码：

from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']

def main():
    """Shows basic usage of the Drive v3 API.
    Prints the names and ids of the first 10 files the user has access to.
    """
    creds = None
    # The file token.pickle 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.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # 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.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('drive', 'v3', credentials=creds)

    # Call the Drive v3 API
    results = service.files().list(
        pageSize=10, fields="nextPageToken, files(id, name)").execute()
    items = results.get('files', [])

    if not items:
        print('No files found.')
    else:
        print('Files:')
        for item in items:
            print(u'{0} ({1})'.format(item['name'], item['id']))

if __name__ == '__main__':
    main()

当我执行代码时，系统会提示我通过 Google 的 OAuth 登录页面登录，以便让我的程序访问我的 Google 帐户。我点击允许，然后立即看到这个页面：

我在没有 VPN 或防火墙的情况下重做此操作，但没有运气，我不知道这是否是我的 OAuth 或项目中的凭据设置有问题。想法？

Answer 1

通过在 PyCharm 中运行解决。 VSCode 也可以。无论出于何种原因，Colab 都会继续抛出错误。

Answer 2

提供解决方案：

run_local_server()打开浏览器时，复制url并使用隐私浏览通过此链接登录。

它对我有用。
