• ”城市公交线路站点数据爬取 + csv站点数据转ShapeFile矢量数据“(二)配置html页面 以及 抓包json数据


    (一)在高德上申请api开发Key,完了配置html页面,我这里直接用了官方的demo页。

    <html>
    <head>
        <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=你的Key"></script> 
    </head>
    
    <body>
        <div id="container"></div>
        <script type="text/javascript">
            var map = new AMap.Map('container');
            /*
            var map = new AMap.Map('container', {
                zoom:11,//级别
                center: [116.397428, 39.90923],//中心点坐标
                viewMode:'3D'//使用3D视图
            });
            */
        </script>
        <style type="text/css">
            #container {width:800px; height: 500px; }
        </style>
        <script type="text/javascript">
            AMap.plugin(["AMap.LineSearch"], function() {
                //实例化公交线路查询类
                var linesearch = new AMap.LineSearch({
                pageIndex: 1, //页码,默认值为1
                pageSize: 1, //单页显示结果条数,默认值为20,最大值为50
                city: "北京", //限定查询城市,可以是城市名(中文/中文全拼)、城市编码,默认值为『全国』
                extensions: "all" //是否返回公交线路详细信息,默认值为『base』
                });
    
                //执行公交路线关键字查询
                linesearch.search('536', function(status, result) {
                //打印状态信息status和结果信息result
                console.log(status, result);
                });
            });
        </script>>
    
    </body>
    
    </html>

    (二)抓包,解析,并存储为csv

    这里需要把py文件和城市公交xlsx放在同一文件夹下。

    import urllib
    from urllib import request
    import pandas as pd
    import json
    import time
    import random
    
    def extratStations(busListSlt):
        #keyName = busListSlt["key_name"]
        busName = busListSlt["name"]
        stationSet = []
        stations = busListSlt["busstops"]
        for bs in stations:
            tmp = []
            tmp.append(bs["id"])
            #tmp.append(keyName)
            tmp.append(busName)
            tmp.append(bs["name"])
            cor = bs["location"].split(",")
            tmp.append(cor[0])
            tmp.append(cor[1])
            stationSet.append(tmp)
        return stationSet
    
    
    def writeStation(listData,fileName):
        data1 = pd.DataFrame(listData)
        data1.to_csv("E:\公交线路\江苏省\江苏点总量\{}".format(fileName),index=False,na_rep="NULL",header=["ID","BusName","StationName","LON","LAT"])
    
    
    def main(cityName):
        df = pd.read_excel("{}.xlsx".format(cityName),header = None)
        BaseUrl = "https://restapi.amap.com/v3/bus/linename?s=rsv3&extensions=all&key=你弟Key&output=json&pageIndex=1&offset=1&"
        headers = {'User-Agent':"你弟UA"}
        
        busStations = []
        for bus in df[0]:
            params = {
                'city':cityName,
                'keywords':bus
            }
            print(bus)
            paramMerge = urllib.parse.urlencode(params) 
            targetUrl = BaseUrl + paramMerge
            #print(targetUrl)
            
            req = urllib.request.Request(url=targetUrl,headers=headers)
            res = urllib.request.urlopen(req)
            content = res.read()
            jsonData = json.loads(content)
            #print(jsonData)
            if (jsonData["buslines"]):
                busList = jsonData["buslines"]
                busListSlt = busList[0]
                
                busStations += extratStations(busListSlt)
                
                #time.sleep(random.random() * random.randint(0,7) + random.randint(0,5))
            else:
                continue
        
        writeStation(busStations, "{}点总量.csv".format(cityName))
    
    listC = ["yancheng","yangzhou","zhenjiang"]#你弟城市公交csv
    for i in listC:
        main(i)

    最终结果如图:
