如何使用Bing maps API获取路线的距离？

import requests

# 替换为你的Bing Maps API密钥
api_key = 'YOUR_BING_MAPS_API_KEY'

# 起点和终点的经纬度坐标
origin = '47.604,-122.332'  # 示例：西雅图
destination = '47.604,-122.333'  # 示例：西雅图附近的一个地点

# 构建请求URL
url = f'https://dev.virtualearth.net/REST/v1/Routes/Driving?o=xml&key={api_key}&wp.0={origin}&wp.1={destination}'

# 发送GET请求
response = requests.get(url)

# 检查响应状态码
if response.status_code == 200:
    # 解析XML响应（也可以选择JSON格式）
    xml_data = response.content
    # 使用合适的库（如lxml或xml.etree.ElementTree）解析XML
    # 这里以lxml为例
    from lxml import etree
    root = etree.fromstring(xml_data)
    
    # 提取距离信息
    route_distance = root.find('.//{http://schemas.microsoft.com/search/local/ws/rest/v1}Distance').text
    print(f'路线距离: {route_distance}')
else:
    print(f'请求失败，状态码: {response.status_code}')
