如何从Spot实例请求中获取Spot InstanceID？

import requests
import json

# 替换为腾讯云的SecretId和SecretKey
secret_id = "your_secret_id"
secret_key = "your_secret_key"

# 替换为要查询的Spot实例的参数
region = "your_region"
instance_id = "your_instance_id"

# 构造请求的URL
url = f"https://cvm.tencentcloudapi.com/?Action=DescribeSpotInstance&Region={region}&InstanceIds.0={instance_id}&Version=2017-03-12"

# 构造请求的头部信息
headers = {
    "Host": "cvm.tencentcloudapi.com",
    "X-TC-Action": "DescribeSpotInstance",
    "X-TC-Timestamp": str(int(time.time())),
    "X-TC-Version": "2017-03-12",
    "X-TC-Region": region,
    "X-TC-RequestClient": "SDK_PYTHON_3.0",
}

# 使用腾讯云的签名方法生成签名串
signature = get_signature(headers, secret_key)

# 将生成的签名串加入到请求头中
headers["Authorization"] = signature

# 发送GET请求
response = requests.get(url, headers=headers)

# 解析返回结果
result = json.loads(response.text)
spot_instance_id = result["Response"]["InstanceSet"][0]["InstanceId"]

print("Spot Instance ID:", spot_instance_id)
