【已解决】汽车之家车型车系数据:支持旧版车系页面

页面 crifan 287浏览 0评论
之前已经完成了:
【已解决】汽车之家车型车系数据:支持新版车系页面
后来发现有些旧版车系页面,html网页结构不一样
所以要再去添加支持
也意味着之前抓包结果会漏掉这些:
旧版车系页面
举例
Q开头
https://www.autohome.com.cn/grade/carhtml/q.html
-》
东风悦达起亚-千里马
且这类旧版车系,在字母页面中,很明显,指导价都是 暂无 没有 没链接的:
-》
一汽丰田-花冠
只是页面内部才有 单个 car的model车型 的(某个范围的)指导价
对于这类页面,需要先去加代码判断 是 新 还是 旧 版本的页面布局:
        carSeriesHtml = response.text
        print("type(carSeriesHtml)=%s" % type(carSeriesHtml)) # <class 'str'>
        # print("carSeriesHtml=%s" % carSeriesHtml)

        foundLevelId = re.search("var\s+levelid\s+=", carSeriesHtml)
        print("foundLevelId=%s" % foundLevelId)
        isNewLayoutHtml = bool(foundLevelId)
        print("isNewLayoutHtml=%s" % isNewLayoutHtml)
        foundShowCityId = re.search("var\s+showCityId\s+=", carSeriesHtml)
        print("foundShowCityId=%s" % foundShowCityId)
        isOldLayoutHtml = bool(foundShowCityId)
        print("isOldLayoutHtml=%s" % isOldLayoutHtml)
然后才能基于不同布局,用不同代码:
        if isOldLayoutHtml:
            # 旧版布局
        elif isNewLayoutHtml
            # 新版布局
            # 详见前贴:【已解决】汽车之家车型车系数据:支持新版车系页面
然后再说,旧版布局中的要抓取的内容和处理逻辑
此处以
东风悦达起亚-千里马
为例,说明要抓取的内容:
其中切换到其他年份款,也是同样的结构:
再去解释处理逻辑:
对于html
            <div class="car_detail " id="tab1-2">
                <div class="models">
                <!--年代-->
                    <div class="header">
                        <div class="car_price">
                            <span class="years">2005款</span>
                            <span class="price">指导价(停售):<strong class="red">6.28万-9.18万</strong></span>
                            <span class="price">二手车价格:<strong class="red"><a class='cd60000' href='//www.che168.com/china/qiya/qianlima/a0_0msdgscncgpiltocsp1exs276/?pvareaid=103693'>0.39万-1.30万</a></strong></span>
            。。。
            <div class="car_detail current" id="tab1-1">
                <div class="models">
                    <!--年代-->
                    <div class="header">
                        <div class="car_price">
                            <span class="years">2006款</span>
                            <span class="price">指导价(停售):<strong class="red">7.28万-8.58万</strong></span>
解析出:
  • carModelYear:2006款
为了和 和之前 新版车系页面 一致,此处:
对于整个车系的数据:采用 第一个model的数据:
对于html
                    <div class="models_info">
                        <dl class='models_pics'>
                            <dt><a href='//car.autohome.com.cn/photolist/series/2305/23796.html?pvareaid=101468'><img
                                src='https://car0.autoimg.cn/upload/spec/1344/t_1344388912334.jpg' width='240'
                                height='180' /></a></dt>
解析出:
对于:
 <div class="car_price">
   <span class="price">指导价(停售):<strong class="red">7.28万-8.58万</strong></span>
解析出:
  • carSeriesMsrp:7.93万
    • =(carSeriesMinPrice + carSeriesMaxPrice) / 2
  • carSeriesMinPrice:7.28万
  • carSeriesMaxPrice:8.58万
然后继续解析每个model数据:
对于html
                <div class="modelswrap">
                    <!-- 信息 start -->
                    <div class="models_info">
                        <dl class='models_prop'>
                            <dt>发动机:</dt>
                            <dd><span>1.3L</span><span>1.6L</span></dd>
                        </dl>
                        <dl class='models_prop'>
                            <dt>变速箱:</dt>
                            <dd><span>手动</span><span>自动</span></dd>
                            <dt>车身结构:</dt>
                            <dd><span>三厢</span></dd>
                        </dl>
解析出:
  • carModelGearBox:手动自动
  • carModelDriveType:空值
  • carModelEmissionStandards:空值
  • carModelPower:1.3L1.6L
  • carModelGroupName:1.3L1.6L 手动自动 三厢
从html
                <table class='models_tab tableline' cellspacing='0' cellpadding='0' border='0'>
                    <tr>
                        <td class='name_d'>
                            <div class='name'><a title='2006款 1.6L MT特别版GL' href='spec/2304/'>2006款 1.6L MT特别版GL</a></div>
                        </td>
                        <td class='price_d'>
                            <div class='price01'>8.18万</div>
                        </td>
解析出:
此处支持 新版车系页面 + 旧版车系页面 的完整代码如下:
