【已解决】汽车之家车型车系数据:支持新版车系页面

数据 crifan 163浏览 0评论
折腾:
【未解决】用Python爬取汽车之家的车型车系详细数据
期间,经过调试,已经支持了新版的 车系详情页面
具体细节是:
从入口
https://www.autohome.com.cn/car/
研究后发现是:
每个车系,都可以从
英文字母页面获取到
从:
https://www.autohome.com.cn/grade/carhtml/a.html
到:
https://www.autohome.com.cn/grade/carhtml/z.html
总结成:
https://www.autohome.com.cn/grade/carhtml/%s.html
针对每个页面去:
找到车系的一些数据:
分别对应着:
然后进去 车系主页=车系详情页
【奥迪A3】奥迪_奥迪A3报价_奥迪A3图片_汽车之家
上图中多数信息前面已抓取
只需要抓剩余的信息即可
另外加上相关的内容,此处是:

和 从源码中js:

        <script type="text/javascript">
            。。。
            var seriesid = '2123';
            var seriesname='哈弗H6';
            var yearid = '0';
            var brandid = '181';
            var levelid = '17';
            var levelname='紧凑型SUV';
            var fctid = '4';
            var SeriesMinPrice='9.80';
            var SeriesMaxPrice='14.10';

提取出的:
  • carSeriesId:2123
  • carBrandId:181
  • carSeriesLevelId:17
    • 用于后续获取停产车型数据的请求的参数
  • carSeriesLevelName:紧凑型SUV
  • carSeriesMinPrice:9.80
    • 单位:万元
  • carSeriesMaxPrice:14.10
    • 单位:万元
另外还要抓取:
相关html:

相关html

解析出:
  • carModelMsrp:10.40万
    • 或 暂无 -》 再替换成 空字符串
以及对于 停售款 也要抓取:
此处经研究,停售款的数据,是单独发送请求,返回json数据的
请求 举例
https://www.autohome.com.cn/ashx/car/Spec_ListByYearId.ashx?seriesid=2123&syearid=10379&levelid=17
返回的json数据,很全面。
举例:
[
    {
        "name": "1.5升 涡轮增压 169马力",
        "speclist": [
            {
                "specid": 36955,

                "specstate": 40,

                "fueltype": 1,
                "fueltypedetail": 1,
                "driveform": "前置前驱",
                "drivetype": "前驱",
                "gearbox": "7挡双离合",
                "evflag": "",
                "newcarflag": "",
                "subsidy": "",
                "paramisshow": 1,
                "videoid": 0,
                "link2sc": "http://www.che168.com/china/hafu/hafuh6/7_8/",
                "price2sc": "7.58万",
                "price": "10.20万",
                "syear": 2019
            }, {
                "specid": 36956,
                "specname": "2019款 红标 1.5GDIT 自动都市版",
                "specstate": 40,
                "minprice": 109000,

                "price2sc": "",
                "price": "10.90万",
                "syear": 2019
            },
。。。
只取用部分字段即可。
核心逻辑是:
                    carModelYear = "%s款" % eachModelDict["syear"]
                    # carModelSpecUrl = "%s/%s" % (CarSpecPrefix, eachModelDict["specid"])
                    carModelSpecUrl = self.genSpecUrl(eachModelDict["specid"])


                    curCarModelDict["carModelGroupName"] = modelGroupName
                    curCarModelDict["carModelYear"] = carModelYear
                    curCarModelDict["carModelEmissionStandards"] = ""
                    curCarModelDict["carModelPower"] = ""
                    curCarModelDict["carModelDriveType"] = eachModelDict["drivetype"]
                    curCarModelDict["carModelGearBox"] = eachModelDict["gearbox"]
                    curCarModelDict["carModelName"] = eachModelDict["specname"]
                    curCarModelDict["carModelSpecUrl"] = carModelSpecUrl
                    curCarModelDict["carModelMsrp"] = eachModelDict["price"]
即可。

(注意旧版车系页面不支持,可以自己加代码忽略,而不至于报错
比如:

        print("foundLevelId=%s" % foundLevelId)
        isNewLayoutHtml = bool(foundLevelId)
