怎么使用python 调用高德地图api查询位置和导航?

news 2025/7/14 19:25:39

环境：

python 3.10

问题描述：

解决方案：

要使用Python调用高德地图API查询位置和导航，需要先注册高德开发者账号并获取API Key。以下是基本步骤：

1. 注册高德开发者账号并获取API Key

访问高德开放平台。
注册账号并登录。
创建一个应用，获取API Key。
在 Python 中使用 requests 库调用 API，建议选择“Web 服务”

2. 安装必要的Python库

你需要安装requests库来发送HTTP请求。

pip install requests

3. 查询位置（地理编码）

地理编码API可以将地址转换为经纬度坐标。

import requestsdef geocode(address, api_key):url = "https://restapi.amap.com/v3/geocode/geo"params = {"key": api_key,"address": address}response = requests.get(url, params=params)data = response.json()if data["status"] == "1" and data["count"] != "0":location = data["geocodes"][0]["location"]return locationelse:return Noneapi_key = "你的API Key"
address = "北京市朝阳区望京"
location = geocode(address, api_key)
print(f"经纬度: {location}")

4. 导航（路径规划）

路径规划API可以根据起点和终点计算导航路线。

def get_route(origin, destination, api_key):url = "https://restapi.amap.com/v3/direction/driving"params = {"key": api_key,"origin": origin,"destination": destination}response = requests.get(url, params=params)data = response.json()if data["status"] == "1":route = data["route"]["paths"][0]return routeelse:return Noneorigin = "116.481028,39.989643"  # 起点经纬度
destination = "116.465302,40.004717"  # 终点经纬度
route = get_route(origin, destination, api_key)
if route:print(f"导航路线: {route['distance']}米, {route['duration']}秒")
else:print("无法获取导航路线")

5. 完整示例

将上述代码整合在一起：

import requestsdef geocode(address, api_key):url = "https://restapi.amap.com/v3/geocode/geo"params = {"key": api_key,"address": address}response = requests.get(url, params=params)data = response.json()if data["status"] == "1" and data["count"] != "0":location = data["geocodes"][0]["location"]return locationelse:return Nonedef get_route(origin, destination, api_key):url = "https://restapi.amap.com/v3/direction/driving"params = {"key": api_key,"origin": origin,"destination": destination}response = requests.get(url, params=params)data = response.json()if data["status"] == "1":route = data["route"]["paths"][0]return routeelse:return Noneapi_key = "你的API Key"
address = "北京市朝阳区望京"
location = geocode(address, api_key)
if location:print(f"经纬度: {location}")origin = locationdestination = "116.465302,40.004717"  # 终点经纬度route = get_route(origin, destination, api_key)if route:print(f"导航路线: {route['distance']}米, {route['duration']}秒")else:print("无法获取导航路线")
else:print("无法获取经纬度")
