​ 公交车路线的信息用的是haoservice这个网站的接口，部分接口是免费的，公交线路的接口首次申请赠送100次的免费使用次数，此后再使用就需要花钱了。需要注册申请APPKEY，关于这个接口的使用可以参考下https://blog.csdn.net/weixin_40992982这篇博客。
​ 请求的uri地址是由城市代号（可以用城市名代替）、哪一路车以及APPKEY三部分拼接组成，其中某地市的车辆信息可以上网爬取获得，我是直接在Python中写了for循环获取了前30路车的信息，通过Console打印发现有一些车辆该地区是没有的，不过这不影响结果。
以延安市宝塔区为例，获取1-30路公交站点信息，代码如下：

   city_name ='延安' #延安市的城市编号
   keywords=1
   apikey='自己的APPKEY'
   #通过循环获得前30路车的信息
   for keywords in range(30):
   station_info_dict= requests.get(
       ' http://apis.haoservice.com/lifeservice/busline/linename?city=%s&keywords=%d&key=%s'% (
                       city_name,
                       keywords,
                       apikey
       )
   )

​ 返回的json内容是这样的↓，需要注意的是返回的信息是两条线路的，一条去程一条回程，在这里考虑到一个公交线路打两次太过繁杂所以只选择一条投在地图上。

具体的内容这两天补完

解析数据看自己需要的信息有哪些，比如我需要busstop中每个站点的名字name，经纬度坐标location，buslines中的公交线路名name。接着就是提取出我们所需的各条公交线路的站点名及坐标，代码如下：

cnt = 0
for cnt in range(len(station_info_dict)):
	x = []  # busstop站点坐标x
	y = []  # busstop站点坐标y
	res=[]  # 经纬度坐标对（维度，经度）
    plots_name = []  # 车站名称
    length = len(stati
