import requests

# 云主机ID
instance_id = 'INSTANCE_ID'

# 请求URL
url = 'https://api.cloud.tencent.com/v2/index.php'

# 请求头
headers = {

    'Action': 'StopInstances',
    'Version': '2017-03-12',

    'InstanceIds.0': instance_id
}

# 发送请求
response = requests.post(url, headers=headers, data=json.dumps(params))

# 处理响应
if response.status_code == 200:
    result = response.json()
    if result['Response']['Error']['Code'] == 'InvalidInstanceID.NotFound':
        print('云主机不存在')
    elif result['Response']['Error']['Code'] == 'InvalidParameter':
        print('参数错误')
    else:
        print('云主机已成功停止')
