我在尝试获取我将用于获取刷新令牌的认证代码时遇到访问被阻止的错误？

Question

这是尝试过的 我将 O Auth 同意屏幕的状态从测试更改为发布并且应用程序范围是外部的然后我创建了 O Auth 客户端 ID 令牌然后我尝试了这个代码但是当我尝试对应用程序进行身份验证时这会出错。

from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

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

CLIENT_SECRETS_FILE = 'client.json'

REDIRECT_URI = 'urn:ietf:wg:oauth:2.0:oob'
flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES, redirect_uri=REDIRECT_URI)
auth_url, _ = flow.authorization_url(prompt='consent')
print(f'Please go to this URL to authorize the application: {auth_url}')
auth_code = input('Enter the authorization code: ')
flow.fetch_token(code=auth_code)
creds = flow.credentials
print(f'Access token: {creds.token}')
print(f'Refresh token: {creds.refresh_token}')

你能发现如何在 python 中做到这一点并解决这个错误吗？

Answer 1

你不能使用 urn:ietf:wg:oauth:2.0:oob，这已经停止了。

你会好运

此示例将使用 creds = flow.run_local_server(port=0) 为您打开同意屏幕，而不是要求您单击一个链接，该链接可能会返回 404 错误，因为您没有运行本地 Web 服务器。
