这就是我使用 requests_oauthlib import OAuth2Session 获取令牌以从 Salesforce 应用程序获取访问令牌的方式

auth_service.py

`from requests_oauthlib import OAuth2Session`

def token_saver(self, token=None):
        print("token to be saved", token)

def get_oauth2_requests(self, auth):
        print("OAuth2", auth)
        client_id = auth['oauth2']['client_id']
        client_secret = auth['oauth2']['client_secret']
        refresh_url = auth['oauth2']['refresh_url']
        token_client = auth['oauth2']['token']
        extra = {
            'client_id': client_id,
            'client_secret': client_secret,
        }
        token = {
            'access_token': 'eswfld123kjhn1v5423',
            'refresh_token': token_client,
            'token_type': 'Bearer',
            'expires_in': '-30'
        }
        client = OAuth2Session(client_id, token=token, auto_refresh_url=refresh_url,
                                auto_refresh_kwargs=extra, token_updater=self.token_saver)
        return client

当它返回 oauth 2 客户端会话时。我们正在向 Salesforce 应用程序发出请求

触发器.py

if auth:
        dataParams["auth"] = auth_object

    print("Body", body)
    print(method)

    if body and method != "GET":
        dataParams["data"] = json.dumps(body)

    if content_type == "application/x-www-form-urlencoded":
        print('Sending application x-www-form-urlencoded')
        dataParams["data"] = body

    dataParams["headers"] = rest_auth.get_headers(auth, content_type)
    print("dataParams", dataParams)

    print("URL", url, "\nMethod", method, "\nDataparams", dataParams)

    response = client.request(method, url, **dataParams)

    return response.text

它适用于一些 oauth 2 应用程序，如 google、asana、Microsoft，但是当它涉及到 salesforce 时，它​​会给出如下错误

Traceback (most recent call last):
  File "F:\git-repos\unified\venv-unified\lib\site-packages\requests_oauthlib\oauth2_session.py", line 477, in request
    url, headers, data = self._client.add_token(

    raise TokenExpiredError()
oauthlib.oauth2.rfc6749.errors.TokenExpiredError: (token_expired)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    raise TokenExpiredError()
oauthlib.oauth2.rfc6749.errors.TokenExpiredError: (token_expired)

我们从 token_saver() 方法获取令牌，如下所示

token to be saved {'access_token': '00D2v000002J66X!AQwAQFxIR.KkLSA74yI53A._b1Rp.uc1UXvBmpWP5erfHwULPj0yDLln0XBTXtfOcKCbPHlxGYTJWAqjMYwHH.JHKpIpgFqf', 'signature': 'O6MoT0xehqoZTvMi0wdwrD5fU+ITAXWixIf0ptt+oew=', 'scope': ['visualforce', 'custom_permissions', 'openid', 'refresh_token', 'wave_api', 'web', 'chatter_api', 'id', 'api', 'eclair_api', 'pardot_api', 'full'], 'instance_url': 'https://ap15.salesforce.com', 'id': 'https://login.salesforce.com/id/00D2v000002J66XEAS/0052v00000f0e07AAA', 'token_type': 'Bearer', 'issued_at': '1616182472230', 'refresh_token': '5Aep861dlMxAL.LhVRuNsLfAdWv0DjJVGBbZuLG8FqcTPokBCeMug96ABAgy7rQ.hAht.x5aTXCAzy5sMTnnLQd'}

我无法从 requests_oauthlib 找出天气问题或请求任何帮助，不胜感激
