在Python中设置googledriveapi

Question

我一直在尝试建立一个非常简单的python程序来连接到googledriveapi，我尝试了很多种不同的方法，但是似乎都没有效果，文档到处都是，我无法让它工作。在

我需要一个方法，不提示用户授予访问权限看到我将访问我自己的个人驱动器，我希望它自动做到这一点，而不是我必须接受每次。在

有谁能给我一个完整的（非常简单的）工作代码模板，我可以用它连接到使用python的googledriveapi？在

这是我最近的一次尝试，你可以修改这个或创建一个新的，我只需要它工作：（

import google.oauth2.credentials
import google_auth_oauthlib.flow
from oauth2client.client import OAuth2WebServerFlow, FlowExchangeError

# Use the client_secret.json file to identify the application requesting
# authorization. The client ID (from that file) and access scopes are required.
flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file(
    'client_secret.json',
    scopes=['https://www.googleapis.com/auth/drive.metadata.readonly'])

# Indicate where the API server will redirect the user after the user completes
# the authorization flow. The redirect URI is required.
flow.redirect_uri = 'http://localhost:8888/'

# Generate URL for request to Google's OAuth 2.0 server.
# Use kwargs to set optional request parameters.
authorization_url, state = flow.authorization_url(
    # Enable offline access so that you can refresh an access token without
    # re-prompting the user for permission. Recommended for web server apps.
    access_type='offline',
    # Enable incremental authorization. Recommended as a best practice.
    include_granted_scopes='true')

print(state)

# code = input('Enter verification code: ').strip()

try:
    credentials = flow.step2_exchange(state)
    print(json.dumps(json.loads(credentials._to_json([])), sort_keys=True, indent=4))
except FlowExchangeError:
    print("Your verification code is incorrect or something else is broken.")
    exit(1)

奖金：我要用这个来上传一个CSV文件，然后用新数据编辑同一个文件

非常感谢你的帮助。在

你应该使用服务帐户。服务帐户就像虚拟用户。服务帐户有自己的驱动器帐户，您可以通过编程方式访问该帐户，并上传和下载。您还可以与服务器帐户共享您自己的google驱动器帐户上的一个或多个文件夹。通过授权它并授予它访问你的驱动器帐户的权限。不会显示同意屏幕或登录屏幕

主要区别在于登录方法。我没有看到一个python服务帐户驱动器的例子，但有一个为谷歌分析api。如果你看一下，改变它应该不难。您将需要使服务帐户凭据您现在拥有的凭据文件将无法工作。在

您需要在代码中更改的主要内容是范围api名称和版本。创建驱动器服务后，代码将与Oauth2格式相同。在
