CMDB资产管理系统开发【day26】:linux客户端开发

客户端疑难点及获取流程

1、linux客户端支持2就可以,python3就是很麻烦

难道你要求所有的客户端都上pytho3吗?

现在从bin的入口进去

HouseStark.ArgvHandler(sys.argv)

2、 core import HouseStark

from core import HouseStark

3、class InfoCollection(object):

def Linux(self):
sys_info = plugin_api.LinuxSysInfo() return sys_info

4、from plugins import plugin_api

5、磁盘是如何获取的

客户端代码如下:

import re def collect():
filter_keys = ['Manufacturer','Serial Number','Product Name','UUID','Wake-up Type']
raw_data = {}
