pip安装

# Install the core librarypip install aliyun-python-sdk-core # Install the ECS management librarypip install aliyun-python-sdk-ecs # Install the RDS management librarypip install aliyun-python-sdk-rds

调用查询ecs主机

创建命令

#!/usr/bin/env python#coding=utf-8from aliyunsdkcore.client import AcsClientfrom aliyunsdkcore.acs_exception.exceptions import ClientExceptionfrom aliyunsdkcore.acs_exception.exceptions import ServerExceptionfrom aliyunsdkecs.request.v20140526.CreateCommandRequest import CreateCommandRequestclient = AcsClient(\' accessKeyId \', \' accessSecret \', \'cn-hangzhou\')request = CreateCommandRequest()request.set_accept_format(\'json\')response = client.do_action_with_exception(request)# python2: print(response) print(str(response, encoding=\'utf-8\'))

这里会返回一个云助手命令id，返回结果：

{\"RequestId\": \"E69EF3CC-94CD-42E7-8926-F133B86387C0\",\"CommandId\": \"c-7d2a745b412b4601b2d47f6a768d3a14\"}

返回结果

安全组部分就省略了，根据API文档

这里先说下公共请求参数

2.1GET请求

https://ecs.aliyuncs.com/?Action=DescribeInstanceStatus RegionId=cn-hangzhou PageSize=1 PageNumber=1 InstanceId.1=i-bp1j4i2jdf3owlhe**** 公共请求参数 

XML返回格式：

 DescribeInstanceStatusResponse PageNumber 1 /PageNumber InstanceStatuses InstanceStatus Status Running /Status InstanceId i-bp1j4i2jdf3owlhe**** /InstanceId /InstanceStatus /InstanceStatuses TotalCount 58 /TotalCount PageSize 1 /PageSize RequestId 746C3444-9A24-4D7D-B8A8-DCBF7AC8BD66 /RequestId /DescribeInstanceStatusResponse 

JSON返回格式

{\"PageNumber\": 1,\"InstanceStatuses\": {\"InstanceStatus\": [ {\"Status\": \"Running\",\"InstanceId\": \"i-bp1j4i2jdf3owlhe****\" } ] },\"TotalCount\": 58,\"PageSize\": 1,\"RequestId\": \"746C3444-9A24-4D7D-B8A8-DCBF7AC8BD66\"}

2.2POST请求
