Question

我正在测试vk.com api以便能够执行搜索。我可以获得令牌，但是当我使用它时，它总是返回错误：＆＃34; access_token已过期＆＃34; 请您帮忙看看代码是否错误，或者是vk配置？

非常感谢

import vk
import requests

url = 'https://oauth.vk.com/access_token?client_id=myClient&client_secret=mySecret&v=5.65&grant_type=client_credentials'
request = requests.get(url).json()
access_token = request["access_token"]

session = vk.Session(access_token)
api = vk.API(session)
search = api.search.getHints(q='python')

错误：

File "C:\Users\gabri\AppData\Local\Programs\Python\Python36-32\lib\site-packages\vk\api.py", line 173, in __call__
    return self._api._session.make_request(self)
  File "C:\Users\gabri\AppData\Local\Programs\Python\Python36-32\lib\site-packages\vk\api.py", line 102, in make_request
    raise error
