通过高德API爬取城市路径

1. 本项目主要服务于物流同行，通过API抓取路径距离

#抓取始发地与目的地距离
#高德API

import requests
import pandas as pd

#获取城市经纬度定位
def get_loc(address, key):
    #接口URL
    url ='https://restapi.amap.com/v3/geocode/geo?'
    #设置参数key、address
    params = {
        'key':key,
        'address':address
        }
    #传入参数，get指令获取信息
    response = requests.get(url, params= params, timeout = 30)
    #将信息JS解析
    r = response.json()
    #获取经纬度
    loc = r['geocodes'][0]['location']
    return loc

#获取始发城市与目标城市的路径距离
def get_distance(origin, destination,key):
    #接口URL
    url = 'https://restapi.amap.com/v3/direction/driving?'
    #设置参数key、address
    params = {

        'origin':origin,
        'destination':destination
        }
    #传入参数，get指令获取信息
    response = requests.get(url, params= params, timeout = 30)
    #将信息JS解析
    r = response.json()
    #获取路径距离
    dis = r['route']['paths'][0]['distance']
    return dis
