在使用python的本地计算机上使用Oauth 2连接到google驱动器时出错

Question

我试图在我的本地计算机上使用Oauth连接到google驱动器。我最初尝试遵循这里概述的快速入门步骤https://developers.google.com/drive/v3/web/quickstart/python，但它无法连接。我会在授权屏幕上得到提示，然后单击“允许”，但随后会重定向到本地主机：8080错误响应消息和日志显示：

Your browser has been opened to visit:

https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive.metadata.readonly&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2F&response_type=code&client_id=xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxx.apps.googleusercontent.com&access_type=offline

If your browser is on a different machine then exit and re-run this application with the command-line parameter

--noauth_local_webserver

我随后尝试简单地使用代码来一步一步地完成它，但是我一直遇到同样的问题：没有返回访问代码，我无法进行身份验证。在

from httplib2 import Http
from oauth2client import file, client, tools
from oauth2client.client import flow_from_clientsecrets

store = file.Storage('credentials.json')
flow = flow_from_clientsecrets('client_secret.json',                        
       scope='https://www.googleapis.com/auth/drive.metadata.readonly',                       
       redirect_uri='http://example.com/auth_return')

print flow
creds = tools.run_flow(flow, store)
print 'access_token: {}'.format(creds.access_token)

service = build('drive', 'v3', http=creds.authorize(Http()))

为了认证到谷歌，你需要首先登录到你的谷歌帐户，然后批准授权。在

脚本告诉您导航到该页面并批准授权。在

https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive.metadata.readonly&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2F&response_type=code&client_id=xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxx.apps.googleusercontent.com&access_type=offline

如果它还没有为你打开，就在浏览器上打开它。在

您可以考虑遵循python quickstart
