python获取OAuth中的auth_code授权码

问题遇到的现象和发生背景

python版本:2.7
在OAuth2.0授权中, 已获得授权链接, 如何通过python 实现获取其授权码auth_code?
正常情况下应该是: 用户点击授权链接,在登录的状态下(如果没有,会跳转到登录页进行登录)会跳转到统一授权页,用户点击授权后,回调开发者提供的callback URL,返回一个临时授权码auth_code.
如何通过python代码实现上面的用户点击授权步骤, 而不需要打开浏览器输入链接点击授权, 再粘贴返回的auth_code, 直接在python脚本里获取返回的URL和临时授权码auth_code呢?

你如果不需要用户参与,那就用客户端模式,而不是授权码模式,正常情况下,你不会有用户的账户信息的

def main():
    # get accessToken
    auth_code = "{authCode}"
    secret_key = "{secretKey}"
    app_id = "{appId}"
    user_id = 0 # {userId}
    grant_type = "access_token"
    oauth_service = OAuthService()

    request = GetAccessTokenRequest(app_id,
                                    auth_code,
                                    secret_key,
                                    grant_type,
                                    user_id)
    response = oauth_service.get_access_token(request)
    access_token = response.data.accessToken

    # init service
    account_service = AccountService()

    # init request header
    request_header = ApiRequestHeader(
        userName="{userName}",
        accessToken=access_token,
        _spec_property_naming=True
    )

    # init request
    account_query_request = ApiAccountQueryRequest(
        accountFields=["pictureOptimizeSegmentStatus", "balance", "userLevel"],
        _spec_property_naming=True
    )

    # init request wrapper
    request_wrapper = GetAccountInfoRequestWrapper(
        header=request_header,
        body=account_query_request,
        _spec_property_naming=True
    )
    response_wrapper = account_service.get_account_info(request_wrapper)
    print(response_wrapper)


if __name__ == '__main__':
    main()
