本文主要是介绍django搭建页面，自动备份网络设备配置，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
原来公司开发团队人员众多，有专门对接运维需求的开发人员，现在要实现点需求只能靠自己写了-_-, 周末在家无事，用django写个简单的页面练练手
django安装，配置
sudo pip3 install dgango
django-admin startproject mysite
django-admin startapp ssh
#models配置
class user(models.Model):
user = models.CharField(max_length=64)
passwd = models.CharField(max_length=64)
#setting配置
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'ssh'
]
