支付宝小程序授权登录（python SDK）

python SDK做授权登录，网上找不到python的例子，现写一个记录下来：

    except Exception as e:

    if not response_content:

    else:

        if response.is_success():

            auth_token = response.access_token

        else:

            print(response.code + "," + response.msg + "," + response.sub_code + "," + response.sub_msg)
