google-python-api-客户端刷新令牌为空

Question

我正在尝试将刷新令牌与 google-python-api-客户端一起使用，以避免每次都必须让用户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，重复验证显然并不理想，所以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，在运行这段代码之后，cred.refresh_token和cred2.refresh_token都是None。如何获取刷新令牌？

Answer 1

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'
)
