python爬取路况信息_高德地图api获取路况信息（python版）

1.依旧是先申请key

2.查看url

https://restapi.amap.com/v3/traffic/status/circle?location=116.3057764,39.98641364&radius=1500&key=你的密钥&extensions=all

3.代码

import pandas as pd

import requests

r =requests.get("https://restapi.amap.com/v3/traffic/status/circle?location=116.3057764,39.98641364&radius=1500&key=你的密钥&extensions=all")

s=r.json()

a=s["trafficinfo"]["roads"]

x=[]

for i in range(len(a)):

s2=a[i]["polyline"]

s3=s2.split(";")

for j in range(len(s3)):

s4=s3[j].split(",")

x.append([a[i]["name"],a[i]["status"],a[i]["speed"],i,s4[0],s4[1]])

c = pd.DataFrame(x)

c.to_csv('roadss.csv')

4.csv结果  排序、路名、车速、路段id、经度、纬度
