使用Rest API时如何获取给定地址的县信息

import requests

def get_county_info(address):
    url = "https://apis.map.qq.com/ws/geocoder/v1/"
    params = {
        "address": address,
        "key": "your_api_key"
    }
    
    response = requests.get(url, params=params)
    data = response.json()
    
    if data["status"] == 0:
        result = data["result"]
        county = result["ad_info"]["district"]
        return county
    else:
        return None

# 示例用法
address = "北京市朝阳区"
county_info = get_county_info(address)
if county_info:
    print("给定地址的县信息为：" + county_info)
else:
    print("获取县信息失败")
