Django的Zoho CRM Python SDK v2初始化问题

我试图将Zoho CRM v2 SDK与我的Django应用程序集成。在Django运行服务器上，我能够获取访问令牌并使用刷新方法将其存储在zcrm_oauthtokens.pkl文件中。然后sdk使用刷新令牌自动刷新访问令牌，所以这里没有问题。然而在我的生产服务器（heroku）上，我得到了这个错误消息：

2019-01-16T11:07:22.314759+00:00 app[web.1]: 2019-01-16 11:07:22,314    - Client_Library_OAUTH - ERROR - Exception occured while fetching oauthtoken from db; Exception Message::'NoneType' object has no attribute 'accessToken'

字符串
在我看来，令牌被保存到文件中，但当sdk试图访问它们时，它正在DB中查找它们，而不是token_persistence_path中指定的文件。
在我的settings.py中，我有这个：

ZOHO_CLIENT_ID = config('ZOHO_CLIENT_ID')
ZOHO_CLIENT_SECRET = config('ZOHO_CLIENT_SECRET')
ZOHO_REDIRECT_URI = config('ZOHO_REDIRECT_URI')
ZOHO_CURRENT_USER_EMAIL = '[email protected]'
ZOHO_PATH = os.path.join(BASE_DIR, 'wills_online', 'zoho')

zoho_config = {'apiBaseUrl': "https://www.zohoapis.com",
               'currentUserEmail': ZOHO_CURRENT_USER_EMAIL,
               'client_id': ZOHO_CLIENT_ID,
               'client_secret': ZOHO_CLIENT_SECRET,
               'redirect_uri': ZOHO_REDIRECT_URI,
               'token_persistence_path': ZOHO_PATH}

在一个视图文件中，我有这个：

            ZCRMRestClient.initialize(zoho_config)
            self.already_run = True

我试过在settings.py中运行ZCRMRestClient.initialize（zoho_config），但没有成功。
我获取访问令牌和刷新令牌的方法，似乎是这样的：

import os
import pprint
from sys import argv

import django
import requests
import zcrmsdk
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'wills_online.settings')
django.setup()

def zoho_refresh_token(code):
    """ supply a self client token from the zoho api credentials from web site """

    zoho_config = {"apiBaseUrl": "https://www.zohoapis.com",
               "currentUserEmail": settings.ZOHO_CURRENT_USER_EMAIL,
               "client_id": settings.ZOHO_CLIENT_ID,
               "client_secret": settings.ZOHO_CLIENT_SECRET,
               "redirect_uri": settings.ZOHO_REDIRECT_URI,
               "token_persistence_path": settings.ZOHO_PATH}

pprint.pprint(zoho_config)

print('working')
address = f'https://accounts.zoho.com/oauth/v2/token?code={code}&redirect_uri={settings.ZOHO_REDIRECT_URI}&client_id={settings.ZOHO_CLIENT_ID}&client_secret={settings.ZOHO_CLIENT_SECRET}&grant_type=authorization_code'
response = requests.post(address)
data = response.json()
pprint.pprint(data)
zcrmsdk.ZCRMRestClient.initialize(zoho_config)
oauth_client = zcrmsdk.ZohoOAuth.get_client_instance()
refresh_token = data['refresh_token']
print(type(refresh_token))
oauth_client.generate_access_token_from_refresh_token(refresh_token, settings.ZOHO_CURRENT_USER_EMAIL)

print(refresh_token)
print('finished')

if __name__ == '__main__':
    zoho_refresh_token(argv[1])

为了将来的参考，您需要在配置字典中定义persistence_handler_class和persistence_handler_path。您还需要一个处理程序类和一个用户定义的模型来存储结果。示例代码如下：

# settings.py

import zcrmsdk
configuration_dictionary = {
    'apiBaseUrl': 'https://www.zohoapis.com',
    'apiVersion': 'v2',
    'currentUserEmail': ZOHO_CURRENT_USER_EMAIL,
    'sandbox': 'False',
    'applicationLogFilePath': '',
    'client_id': ZOHO_CLIENT_ID,
    'client_secret': ZOHO_CLIENT_SECRET,
    'redirect_uri': ZOHO_REDIRECT_URI,
    'accounts_url': 'https://accounts.zoho.com',
    'access_type': 'online',
    'persistence_handler_class': ZOHO_HANDLER_CLASS,
    'persistence_handler_path': ZOHO_HANDLER_PATH,
}
zcrmsdk.ZCRMRestClient.initialize(configuration_dictionary)

# zoho.models.py

from django.db import models
from zcrmsdk.OAuthClient import ZohoOAuthTokens

class ZohoOAuthHandler:
    @staticmethod
    def get_oauthtokens(email_address):
        oauth_model_instance = ZohoOAuth.objects.get(user_email=email_address)
        return ZohoOAuthTokens(oauth_model_instance.refresh_token,
                               oauth_model_instance.access_token,
                               oauth_model_instance.expiry_time,
                               user_email=oauth_model_instance.user_email)

    @staticmethod
    def save_oauthtokens(oauth_token):
        defaults = {
            'refresh_token': oauth_token.refreshToken,
            'access_token': oauth_token.accessToken,
            'expiry_time': oauth_token.expiryTime,
        }
        ZohoOAuth.objects.update_or_create(user_email=oauth_token.userEmail, defaults=defaults)

class ZohoOAuth(models.Model):

    refresh_token = models.CharField(max_length=250)
    access_token = models.CharField(max_length=250)
    expiry_time = models.BigIntegerField()
    user_email = models.EmailField()

字符串
在本例中，ZOHO_HANDLER_CLASS = 'ZohoOAuthHandler'和ZOHO_HANDLER_PATH = 'zoho.models'
第一次使用它时，您需要从https://accounts.zoho.com/developerconsole获得一个grant_token。对于作用域，请使用aaaserver.profile.READ,ZohoCRM.modules.ALL启动（请参阅https：//www.zoho.com/crm/developer/docs/api/oauth-overview.html#scopes）
在使用API之前，您需要在django shell中运行以下代码。这将使用授权令牌来生成您的初始访问和刷新令牌。之后，API应该处理刷新您的访问令牌。

grant_token = GRANT_TOKEN
import zcrmsdk
oauth_client = zcrmsdk.ZohoOAuth.get_client_instance()
oauth_tokens = oauth_client.generate_access_token(grant_token)
