我正在尝试将刷新令牌与 google-python-api-client 一起使用,以避免用户每次都对应用程序进行身份验证。

我有以下代码通过让用户每次都进行身份验证来构建健身服务

from apiclient.discovery import build
from oauth2client import tools
from oauth2client.file import Storage
from oauth2client.client import AccessTokenRefreshError
from oauth2client.client import OAuth2WebServerFlow
import httplib2

scope = "https://www.googleapis.com/auth/fitness.activity.read"
flow = OAuth2WebServerFlow(client_id, client_secret, scope, redirect_url)
auth_uri = flow.step1_get_authorize_url()
print auth_uri

token = str(input("Enter token"))

cred = flow.step2_exchange(token)
storage = Storage("credentials_file")
storage.put(cred)

storage = Storage("credentials_file")
cred2 = storage.get()

http = httplib2.Http()
http = cred2.authorize(http)
service = build('fitness', 'v1',http=http)

但是,重复身份验证显然并不理想,因此我试图将其转换为可以使用刷新令牌刷新访问令牌的代码。但是,运行此代码后, cred.refresh_token 和 cred2.refresh_token 都为 None。如何获取刷新令牌?

更新,我知道为什么它是空的

这一行:

flow = OAuth2WebServerFlow(client_id, client_secret, scope, redirect_url)

需要编辑如下:

flow = OAuth2WebServerFlow(
            client_id,
            client_secret,
            scope,
            redirect_url,
            approval_prompt='force'
)
