使用Python獲取ECS相關信息2

上一次我們已經知道如何用python獲取ECS信息了,不知道的可以點這裏

1.返回數據格式

通過上回的代碼,我們將會獲得如下的數據(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密鑰","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":""}]}}

稍微排版一下是這樣的

	]
}
}

2.數據處理

接下來我們就要用python對這些數據進行處理,恕本人才疏學淺,用了最蠢的方法來處理,直接上代碼:

首先用python中的json.loads方法將獲取到的json數據轉化爲字典

dictA=json.loads(response)

之後用for循環將一層一層的字典,列表的嵌套提取出來,並且存儲到一個新的字典裏面去:

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]

這樣的話,我們就已經將這個ECS的信息存儲到diceEnd這個字典裏面了,由於本人決定只把數據的值的部分輸出到表格中,所以使用以下代碼把剛剛生成的dict轉換爲一個list

listC=list(dictEnd.values())

3.輸出到表格

這裏使用openpyxl這個模塊將內容輸出到表格

wb = Workbook()
ws=wb.active
ws.append(listC)
wb.save('txt.xlsx')

4.完整代碼

from aliyunsdkcore.client import AcsClient
from aliyunsdkecs.request.v20140526 import DescribeInstancesRequest
from openpyxl import Workbook
import json

#創建AcsClient實例
client = AcsClient(
	"你的AccessKey",
	"你的AccessKey secret",
	"地域"
);

# 創建request，並設置參數
request = DescribeInstancesRequest.DescribeInstancesRequest()
request.set_PageSize(10)

# 發起API請求並顯示返回值
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]


#轉化爲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')

以上純屬本人理解,有什麼錯誤的地方還望各位大神指正
