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
def selectlog(self): ##查询SEL日志,13版pdf815页
##post https://device_ip/redfish/v1/Systems/system_id/LogServices/LogService_id/Actions/Oem/Huawei/LogService.QuerySelLogEntries
url_selcetSELlog = self.URLprefix+'/redfish/v1/Systems/1/LogServices/Log1/Actions/Oem/Huawei/LogService.QuerySelLogEntries' ##LogService_id==Log1
if token != 0:
header = {
"Content-Type": "application/json",
"X-Auth-Token": token
