1. 报错出现的代码：
self.authorize_ip = oauth.remote_app('oauth_ip', app_key='OAUTH_IP')
self.authorize_ip.authorized_response()
2. 报错信息如下：
E:\pythonPrj\CICD-TEST\venv\Scripts\python.exe E:/pythonPrj/CICD-TEST/flask_test.py

Access denied:error=The session is unavailable because no secret key was set. Set the secret_key on the application to something unique and secret.
3. 报错根因：
- session背景：flask中，用户登录后通过session的方式，存储登录的用户信息，便于网页中标识登录用户的信息，或携带用户的信息完成一些数据的持久化操作。
- 错误来源：flask中使用session需要配置密钥，flask中则需要手动配置密钥。django会自动生成secret_key。
4. 解决措施：
- 在配置文件中添加SECRET_KEY = ‘zidingyisecretkey’，直接复制我的添加到config文件里面就行。
import os
from celery.schedules import crontab
class Config(object):
SECRET_KEY = 'zidingyisecretkey'
APP_NAME = 'app'
PROJECT_PATH = os.path.abspath(os.path.join(os.path.dirname(__file__), '..'))
SERVER_HOST = '192.168.3.8'
SERVER_PORT = '8084'
HOST_ADDRESS = 'http:{0}:{1}'.format(SERVER_HOST, SERVER_PORT)
DEBUG = True
