【问题描述】：

尝试使用 requests_oauthlib 从 Listrak API 获得有效响应，但我得到的只是无效凭据。已尝试重置密钥但同样的问题。代码如下，部分替换为我代码中的实际键：

#Imports
import requests
import requests_oauthlib
from oauthlib.oauth2 import BackendApplicationClient

#Keys
id = <client_id>
secret = <client_secret>
#Token URL
token_url = 'https://auth.listrak.com/OAuth2/Token'

#Auth Request
client = BackendApplicationClient(client_id=id)
oauth = requests_oauthlib.OAuth2Session(client=client)
token = oauth.fetch_token(
    token_url=token_url, client_id=id, client_secret=secret)

调试日志：

我注意到第四行中的“auth”参数看起来像'auth': <requests.auth.HTTPBasicAuth object at 0x03EBC5F8>，这对我来说似乎很奇怪。似乎应该有一些价值？任何建议都非常感谢。

【参考方案1】：

我让它在使用旧版本 oauth 库的旧服务器上工作，但是当我更新时，Listrak 停止工作，就像它为你所做的那样，我感觉这就是你在这里所经历的.

我还没有完全弄清楚幕后到底发生了什么，但是当我在oauth.fetch_token() 中通过include_client_id=True 时，我得到了这个工作。所以它会是：

token = oauth.fetch_token(
    token_url=token_url, 
    client_id=id, 
    client_secret=secret,
    include_client_id=True)

（为清楚起见进行了编辑）

【讨论】：

欢迎来到 SO。我有点疑惑，你是说他的token = oauth.fetch_token( token_url=token_url, client_id=id, client_secret=secret)应该换成token = oauth.fetch_token( token_url=token_url, include_client_id=client_id, client_secret=secret)？。如果是这样，为什么不在你的答案中写下所有内容，以帮助像我这样容易混淆的人以及其他未来的读者。谢谢。

对表述不够清晰深表歉意，并感谢您的反馈！我的意思是它是一个 additional 参数，像这样：token = oauth.fetch_token( token_url=token_url, client_id=id, client_secret=secret, include_client_id=True)。我还注意到我使用了 client_id 而不是 True，这可能更有意义。
