华为2288HV5获取cpu、内存、存储等参数信息

华为2288HV5获取cpu、内存、存储等参数信息，采用redfish协议。华为的技术支撑团队很给力，获取资料很全面，讲解也很到位。所以第一个redfish案例就是用华为。

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

###原理：cpu、内存、存储分别使用不同的url获取到值，如url不一致只分别修改对应的第一个url即可，后面的详细参数的URL函数自动提取
##sel日志单独使用URL获取

class GetHostInfo(object):
    def __init__(self,ipaddr,username,password):
        self.URLprefix='https://'+ipaddr.strip()
        self.username=username.strip()
        self.password=password.strip()
        global token    ##同时存在4-5个token链接，每个token链接时间为5分钟，可以自己设置。
        token=0
        tokenurl=self.URLprefix+'/redfish/v1/SessionService/Sessions'
        print(tokenurl)
        data={
            "UserName":self.username,
            "Password":self.password
            }
        header={
            "Content-Type":"application/json"
            }
        re1=requests.post(tokenurl,json.dumps(data),headers=header,verify=False)
        #print (re1.status_code)
        if re1.status_code == 201:
            #print (re1.json())
            #print (re1.headers)
            print (re1.headers['X-Auth-Token'])
            token=re1.headers['X-Auth-Token']
        else:
            pass
    def GetInfo(self,URL_suffix):  #定义总获取函数，传参url的后半部分。如'/redfish/v1/Systems/1/Memory'
        urlset=self.URLprefix+URL_suffix
        if token !=0:
            header = {
                "Content-Type":"application/json",
                "X-Auth-Token":token
                }
            re1=requests.get(urlset,headers=header,verify=False)
            #print(re1.status_code)
            return (re1.json())
        else:
            pass
