Zoho CRM Python SDK v2 Django 初始化问题

问题描述 投票：0回答：1

我正在尝试将 Zoho CRM v2 SDK 与我的 Django 应用程序集成。 在 Django runserver 上，我能够获取访问令牌并使用刷新方法并将它们存储在 zcrm_oauthtokens.pkl 文件中。然后sdk会自动使用刷新令牌刷新访问令牌，所以这里没有问题。但是在我的生产服务器（heroku）上，我收到此错误消息：

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'

在我看来，令牌正在保存到文件中，但是当 sdk 尝试访问它们时，它是在数据库中查找它们，而不是在 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}

在视图文件中我有这个：

            response = record.create()
            # save account id to db for future updates
            zoho_ob.account = response.details['id']
            zoho_ob.save()

    except ZCRMException as ex:

        logger.log(1, ex.error_message)
        logger.log(1, ex.error_details)
        logger.log(1, ex.error_content)
        print(ex.status_code)
        print(ex.error_message)
        print(ex.error_content)
        print(ex.error_details)

我尝试在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有效：

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')

为了将来参考，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()

在此示例中 

ZOHO_HANDLER_CLASS = 'ZohoOAuthHandler'
和 
ZOHO_HANDLER_PATH = 'zoho.models'

第一次使用此功能时，您将需要来自 

https://accounts.zoho.com/developerconsole
的 grant_token。对于范围，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。这使用授予令牌来生成您的初始访问令牌和刷新令牌。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)
