如何从JSON URL拉取数据？

import requests
import json

def fetch_data_from_json_url(url):
    response = requests.get(url)
    if response.status_code == 200:
        json_data = response.json()
        # 在这里对json_data进行进一步处理
        return json_data
    else:
        print("请求失败，状态码：", response.status_code)
        return None

# 示例使用腾讯云API的JSON URL
url = "https://api.qcloud.com/v2/index.php?Action=DescribeInstances&Region=ap-guangzhou&SecretId=xxx&Timestamp=xxx&Nonce=xxx&Signature=xxx"
data = fetch_data_from_json_url(url)
if data:
    print(data)
