当我尝试使用刷新令牌时，Zoom api 出现错误

Question

几个月来，我们一直在尝试让缩放刷新令牌发挥作用，但没有成功。谁能告诉我我们哪里出了问题？

token = base64.b64encode(
    (getConfig().ZOOM_CLIENT_ID + ":" + getConfig().ZOOM_SECRET).encode('ascii'))
token = 'Basic ' + token.decode('UTF-8')

print('Token')
print(token)

result = session.post(f'https://zoom.us/oauth/token',
                      json={
                          'grant_type': 'refresh_token',
                          'refresh_token': refresh_token
                      }, 
                      headers={'Authorization': token, 'Content-Type': 'application/x-www-form-urlencoded'})

{'reason': 'unsupported grant type', 'error': 'unsupported_grant_type'}

结果应该是这样的
