使用Python获取ECS相关信息2
上一次我们已经知道如何用python获取ECS信息了,不知道的可以点这里
1.返回数据格式
通过上回的代码,我们将会获得如下的数据(json格式)
{"PageNumber":1,"TotalCount":1,"PageSize":10,"RequestId":"CF15510B-9510-4E04-939B-F48C453D0E62","Instances":{"Instance":[{"ImageId":"centos_7_04_64_20G_alibase_201701015.vhd","VlanId":"","EipAddress":{"IpAddress":"","AllocationId":"","InternetChargeType":""},"ZoneId":"cn-shanghai-b","IoOptimized":true,"SerialNumber":"41b2b827-014b-4723-bcdf-a5764c9d1c2e","Cpu":1,"Memory":2048,"DeviceAvailable":true,"SecurityGroupIds":{"SecurityGroupId":["sg-uf6fq26zc62t0u0t8ftr"]},"SaleCycle":"","AutoReleaseTime":"","OSType":"linux","ResourceGroupId":"","OSName":"CentOS 7.4 64位","InstanceNetworkType":"vpc","HostName":"aliyun-sh","CreationTime":"2018-12-05T06:51Z","RegionId":"cn-shanghai","DeletionProtection":false,"OperationLocks":{"LockReason":[]},"ExpiredTime":"2019-06-05T16:00Z","InnerIpAddress":{"IpAddress":[]},"InstanceTypeFamily":"ecs.n4","InstanceId":"i-uf6gchn2j65r5scbn6rz","NetworkInterfaces":{"NetworkInterface":[{"MacAddress":"00:16:3e:02:0e:a2","PrimaryIpAddress":"172.19.214.188","NetworkInterfaceId":"eni-uf68mu7aigxbcs3huv90"}]},"InternetMaxBandwidthIn":500,"CreditSpecification":"","InternetChargeType":"PayByBandwidth","SpotStrategy":"NoSpot","StoppedMode":"Not-applicable","InternetMaxBandwidthOut":1,"VpcAttributes":{"NatIpAddress":"","PrivateIpAddress":{"IpAddress":["172.19.214.188"]},"VSwitchId":"vsw-uf6a4tfeug6t05akf9w92","VpcId":"vpc-uf6eyafn4cmj5nol253d4"},"SpotPriceLimit":0.0,"StartTime":"2018-12-14T02:33Z","KeyPairName":"哇咔咔的sh密钥","InstanceName":"哇咔咔的上海ECS","Description":"","PublicIpAddress":{"IpAddress":["47.100.239.99"]},"InstanceType":"ecs.n4.small","Status":"Running","Recyclable":false,"ClusterId":"","GPUSpec":"","GPUAmount":0,"InstanceChargeType":"PrePaid","DedicatedHostAttribute":{"DedicatedHostId":"","DedicatedHostName":""},"DeploymentSetId":""}]}}稍微排版一下是这样的

}接下来我们就要用python对这些数据进行处理,恕本人才疏学浅,用了最蠢的方法来处理,直接上代码:
首先用python中的json.loads方法将获取到的json数据转化为字典
dictA=json.loads(response)之后用for循环将一层一层的字典,列表的嵌套提取出来,并且存储到一个新的字典里面去:
dictEnd={}
dictB=dictA['Instances']
listA=dictB['Instance']
dictC=listA[0]
for i in dictC:
if(type(dictC[i])==dict):
dictD=dictC[i]
if(type(dictD)==dict):
for d in dictD:
dictE=dictD[d]
if(type(dictE)==list):
listB=dictE
if listB:
if(type(listB[0])==dict):
dictF=listB[0]
for f in dictF:
dictEnd[f]=dictF[f]
else:
dictEnd[d] = dictD[d]
elif(type(dictE)==dict):
dictG=dictE
else:
dictEnd[d]=dictD[d]
else:
dictEnd[i]=dictC[i]
这样的话,我们就已经将这个ECS的信息存储到diceEnd这个字典里面了,由于本人决定只把数据的值的部分输出到表格中,所以使用以下代码把刚刚生成的dict转换为一个list
listC=list(dictEnd.values())3.输出到表格
这里使用openpyxl这个模块将内容输出到表格
wb = Workbook()
ws=wb.active
ws.append(listC)
wb.save('txt.xlsx')4.完整代码
from aliyunsdkcore.client import AcsClient
from aliyunsdkecs.request.v20140526 import DescribeInstancesRequest
from openpyxl import Workbook
import json
#创建AcsClient实例
client = AcsClient(
"你的AccessKey",
"你的AccessKey secret",
"地域"
);
# 创建request，并设置参数
request = DescribeInstancesRequest.DescribeInstancesRequest()
request.set_PageSize(10)
# 发起API请求并显示返回值
response = client.do_action_with_exception(request)
dictA=json.loads(response)
dictEnd={}
dictB=dictA['Instances']
listA=dictB['Instance']
dictC=listA[0]
for i in dictC:
if(type(dictC[i])==dict):
dictD=dictC[i]
if(type(dictD)==dict):
for d in dictD:
dictE=dictD[d]
if(type(dictE)==list):
listB=dictE
if listB:
if(type(listB[0])==dict):
dictF=listB[0]
for f in dictF:
dictEnd[f]=dictF[f]
else:
dictEnd[d] = dictD[d]
elif(type(dictE)==dict):
dictG=dictE
else:
dictEnd[d]=dictD[d]
else:
dictEnd[i]=dictC[i]
#转化为list
listC=list(dictEnd.values())
for i in range(len(listC)):
if (type(listC[i])==list):
listC[i]=""
for i in listC:
print(i)
#excel
wb = Workbook()
ws=wb.active
ws.append(listC)
wb.save('txt.xlsx')以上纯属本人理解,有什么错误的地方还望各位大神指正
