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
-》
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：
-》
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：
1 2 3 4 5 6 7 8 9 10 11 12 | 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：
1 2 3 4 5 | 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
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | <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
1 2 3 4 5 | <div class="models_info"> <dl class='models_pics'> <dt><a href='//car.autohome.com.cn/photolist/series/2305/23796.html?pvareaid=101468'><img height='180' /></a></dt> |
解析出：
- carSeriesMainImgUrl：https://car0.autoimg.cn/upload/spec/1344/t_1344388912334.jpg
对于：
1 2 | <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
1 2 3 4 5 6 7 8 9 10 11 12 13 | <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
1 2 3 4 5 6 7 8 | <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：
- carModelName：2006款 1.6L MT特别版GL
- carModelSpecUrl：https://www.autohome.com.cn/spec/2304/
- carModelMsrp：8.18万
此处支持 新版车系页面 + 旧版车系页面 的完整代码如下：
