戴尔R740服务器获取cpu、内存、硬盘参数信息。

戴尔R740服务器获取cpu、内存、硬盘参数信息。使用redfish协议，只使用了system的一个总URL即可获取所有参数。

import requests
import json
requests.packages.urllib3.disable_warnings()

##使用一个system总的URL分别获取到cpu、内存、存储三个url.所以只修改system的URL即可
##sel日志单独使用URL获取

token=0
tokenurl=self.URLprefix+'/redfish/v1/Sessions'  ##dell获取token的ID
