我正在使用谷歌官方 oauth2client.client 访问谷歌加上api。我有一个存储在数据库中的刷新 token (不会过期),并且需要从中重新创建临时“凭据”(访问 token )。

但我无法通过谷歌提供的官方图书馆找到一种方法。

所以我绕过它:使用 urllib 访问 API,它给了我一个新的来自 refresh_token 的 access_token。使用 access_token 我可以使用该库。

我一定是错过了什么!

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 = credentials.authorize(httplib2.Http())
service = discovery.build('plus', 'v1', http=http)
google_request = service.people().get(userId='me')
result = google_request.execute(http=http)

最佳答案

我使用:oauth2client.client.GoogleCredentials

    cred = oauth2client.client.GoogleCredentials(access_token,client_id,client_secret,
refresh_token,expires_at,"https://accounts.google.com/o/oauth2/token",some_user_agent)
http = cred.authorize(httplib2.Http())
cred.refresh(http)
self.gmail_service = discovery.build('gmail', 'v1', credentials=cred)
