相关疑难解决方法(0)

我正在使用googles官方oauth2client.client访问google plus api.我有一个存储在数据库中的刷新令牌(不会过期),需要从中重新创建临时"凭据"(访问令牌).

但我无法找到一种方法来与谷歌提供的官方图书馆这样做.

所以我讨厌它:使用urllib访问API,从refresh_token给我一个新的access_token.使用access_token我可以使用该库.

我一定是想念一下!

from apiclient import discovery
from oauth2client.client import AccessTokenCredentials
from urllib import urlencode
from urllib2 import Request , urlopen, HTTPError
import json

# ==========================================

def access_token_from_refresh_token(client_id, client_secret, refresh_token):
  request = Request('https://accounts.google.com/o/oauth2/token',
    data=urlencode({
      'grant_type':    'refresh_token',
      'client_id':     client_id,
      'client_secret': client_secret,
      'refresh_token': refresh_token
    }),
    headers={
      'Content-Type': 'application/x-www-form-urlencoded',
      'Accept': 'application/json'
    }
  )
  response = json.load(urlopen(request))
  return response['access_token']

# ==========================================

access_token = access_token_from_refresh_token(CLIENT_ID, CLIENT_SECRET, REFRESH_TOKEN)

# now I can use the library properly
credentials = AccessTokenCredentials(access_token, "MyAgent/1.0", None)
http = …
