实现python的jsonp请求

import json
import requests

def jsonp_request(url, callback):
    response = requests.get(url)
    data = response.text
    # 提取回调函数的参数部分
    json_data = data[data.index('(') + 1: data.rindex(')')]
    # 将参数部分解析为JSON对象
    json_obj = json.loads(json_data)
    return json_obj

# 示例：请求腾讯云API获取服务器实例列表
url = 'https://api.qcloud.com/v2/index.php?Action=DescribeInstances&Region=ap-guangzhou&SecretId=xxx&Timestamp=xxx&Nonce=xxx&Signature=xxx&callback=callback'
callback = 'callback'
result = jsonp_request(url, callback)
print(result)
