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 { "PageNumber":1, "TotalCount":1, "PageSize":10, "RequestId":"04F89A1C-EC73-4F6C-84EE-F2703732DE09", "Instances": { "Instance": [ { "ImageId":"centos_7_03_64_20G_alibase_20170818.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 7.3 64位", "InstanceNetworkType":"vpc", "HostName":"aliyun", "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":"2018-12-05T06:55Z", "KeyPairName":"哇咔咔的密钥", "InstanceName":"哇咔咔", "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":"" } ] } } 2.数据处理 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
