地铁交通导航查询的代码通常涉及API调用、地理信息系统(GIS)技术和数据结构管理。下面是一个简单的示例,说明如何在Python中使用第三方库如`geopy`和`requests`来获取地铁线路信息:
```python
import requests
from geopy.geocoders import Nominatim
# 初始化地图API
def get_directions(origin, destination):
# 使用Nominatim查找地址坐标
geolocator = Nominatim(user_agent="my_app")
origin_location = geolocator.geocode(origin)
destination_location = geolocator.geocode(destination)
# 假设有一个地铁API,比如中国的高德地图API,返回json数据
base_url = "https://restapi.amap.com/v3/direction"
params = {
'key': 'your_amap_api_key', # 你需要替换为你自己的API密钥
'origin': origin_location.address,
'destination': destination_location.address,
'mode': 'subway' # 指定查询模式为地铁
}
response = requests.get(base_url, params=params)
if response.status_code == 200:
data = response.json()
# 解析并提取路线信息,如起点站、终点站、换乘站等
route = data['routes'][0]
return route
else:
return None
# 示例使用
origin = "北京西站"
destination = "天安门广场"
direction_info = get_directions(origin, destination)
if direction_info:
print(f"从{origin}到{destination}的地铁线路信息:", direction_info)
else:
print("获取路径失败")
