如何控制云主机

import requests

# 腾讯云API密钥

# 启动云主机
def start_instance():

        'Content-Type': 'application/json'
    }
    response = requests.post(url, headers=headers)
    return response.json()

# 停止云主机
def stop_instance():
    url = f'https://api.cloud.tencent.com/v2/index.php?Action=StopInstances&Version=2017-03-12&Region=gz&InstanceIds.0={instance_id}'

    }
    response = requests.post(url, headers=headers)
    return response.json()

# 示例调用
print(start_instance())
print(stop_instance())
