本文介绍了如何使用Python的requests和json库调用高德地图API，获取从一个起点到终点的驾车路线，并计算沿途站点之间的距离。

import requests
import json

key = 'f168d2559ec181919f85b32e6d5d6bbc' #在高德地图的控制台获取key,并填写
points = []
distinces = []
def routes(origin,destination):
    parameters = {'key':key,'origin':origin,'destination':destination}
    response = requests.get('https://restapi.amap.com/v3/direction/driving?parameters',params=parameters)
    jd = json.loads(response.text)
    print(jd)
    print(jd['route']['paths'][0]['steps'])
    for step in jd['route']['paths'][0]['steps']:
        for tmc in step['tmcs']:
            if int(tmc['distance'])>=50:
                tmp_pos = str(tmc['polyline']).split(';')
                if tmp_pos[0] not in points:
                    if tmp_pos[0] != origin:
                        points.append(tmp_pos[0])
                if tmp_pos[len(tmp_pos) - 1] not in points:
                    points.append(tmp_pos[len(tmp_pos) - 1])
    print(points)
    num = 0
    s = 0
    distincttotal = 0
    for point in points:
        if s == 0:
            print(origin + '-------' + point)#第1个不是站点位置
            parameters = {'key': key, 'origins': origin, 'destination': points, 'type': 0}

        else:
            print(points[s - 1] + '-------' + point)
            parameters = {'key': key, 'origins': point, 'destination': points[s - 1], 'type': 0}

        response = requests.get('https://restapi.amap.com/v3/distance?parameters', params=parameters)
        distince = json.loads(response.text)['results'][0]['distance']
        print(distince)
        distincttotal = distincttotal + int(distince)
        distinces.append(distincttotal)
        print(distincttotal)
        s = s + 1

    print(len(points))
    print(len(distinces))


dict=routes('102.6853,25.0082','102.6631,25.0657')
