如何从纬度和经度点获取城市名称？

import requests

def get_city_name(latitude, longitude, api_key):
    url = f"https://maps.googleapis.com/maps/api/geocode/json?latlng={latitude},{longitude}&key={api_key}"
    response = requests.get(url)
    data = response.json()
    for component in data['results'][0]['address_components']:
        if "locality" in component["types"]:
            return component["long_name"]

# 示例用法
latitude = 31.2304
longitude = 121.4737
api_key = "YOUR_API_KEY"
city_name = get_city_name(latitude, longitude, api_key)
print(city_name)  # 输出：上海市
