【已解决】汽车之家车型车系数据:优化去掉js加速抓取车型参数配置

折腾:
【已解决】汽车之家车型车系数据:抓取车型的详细参数配置
期间,已经基本上实现了获取参数配置数据了。
但是有个问题:
进入参数配置页面时,是通过:
        # https://car.autohome.com.cn/config/spec/43593.html
        print("carConfigSpecUrl=%s" % carConfigSpecUrl)
        self.crawl(carConfigSpecUrl,
            fetch_type="js",
            callback=self.carConfigSpecCallback,
            save=carModelDict,
        )
即运行了js部分的
这样后续的
        """
        <table class="tbcs" id="tab_0" style="width: 932px;">
            <tbody>
                <tr>
                    <th class="cstitle" show="1" pid="tab_0" id="nav_meto_0" colspan="5">
                    <h3><span>基本参数</span></h3>
                    </th>
                </tr>
                <tr data-pnid="1_-1" id="tr_0">
        """
        tbodyDoc = response.doc("table[id='tab_0'] tbody")
        print("tbodyDoc=%s" % tbodyDoc)
才不会是空的。
才能获取,运行了js后的,html中表格部分的值,才是已合并后的文字。
但是带来了问题:
每个页面都需要额外运行js,很慢。
如果批量爬取,速度太慢。
现在希望是实现加速:去掉js执行部分。
看看不用js返回的html中,能否直接从json数据中获取这些值。
之前就研究过的,config的json中包含对应的值。
看看如何去提取
不过此处由于单个车系车型太多,不好分析具体的值
换个车系里车型少的,就2个的
https://car.autohome.com.cn/config/spec/42875.html
去看看
发现config处理后:

其中的内容,很方便提取,也和运行js后的结果是一样的
对应着页面上的:
https://car.autohome.com.cn/config/spec/42875.html
所以,还是容易处理的。
所以去把之前的,从html中提出first value的代码:
    def getItemFirstValue(self, rootDoc, trNumber, isRespDoc=False):
        """
        <tr data-pnid="1_-1" id="tr_2">
            <th>
                <div id="1149"><a href="https://car.autohome.com.cn/baike/detail_7_18_1149.html#pvareaid=2042252">能源类型</a>
                </div>
            </th>
            <td style="background:#F0F3F8;">
                <div>纯电动</div>
            </td>


        <tr data-pnid="1_-1" id="tr_3">
            <th>
                <div id="0">上市<span class="hs_kw40_configxv"></span></div>
            </th>
            <td style="background:#F0F3F8;">
                <div>2019.11</div>
            </td>
            <td>
                <div>2019.11</div>
            </td>
            <td>
                <div></div>
            </td>
            <td>
                <div></div>
            </td>
        </tr>
        """
        trQuery = "tr[id='tr_%s']" % trNumber
        # print("trQuery=%s" % trQuery)
        trDoc = rootDoc.find(trQuery)
        # print("trDoc=%s" % trDoc)
        tdDocGenerator = trDoc.items("td")
        # print("tdDocGenerator=%s" % tdDocGenerator)
        tdDocList = list(tdDocGenerator)
        # print("tdDocList=%s" % tdDocList)
        firstTdDoc = tdDocList[0]
        # print("firstTdDoc=%s" % firstTdDoc)
        firstTdDivDoc = firstTdDoc.find("div")
        print("firstTdDivDoc=%s" % firstTdDivDoc)
        if isRespDoc:
            respItem = firstTdDivDoc
        else:
            firstItemValue = firstTdDivDoc.text()
            respItem = firstItemValue
        print("respItem=%s" % respItem)
        return respItem
去改为从config中提取
这样就不用run js了。
最后代码是:
    def getItemFirstValue(self, inputContent, itemIndex):
        print("in getItemFirstValue")
        # firstItemValue = self.extractTrFirstTdValue(inputContent, itemIndex)
        firstItemValue = self.extractDictListFirstValue(inputContent, itemIndex)
        return firstItemValue

            distanceNumber = foundYearDistance.group("distanceNumber")
            distanceUnit = foundYearDistance.group("distanceUnit")
            carModelWholeWarranty = "%s年或%s万%s" % (warrantyYear, distanceNumber, distanceUnit)
        else:

        curCarModelDict = response.save
        print("curCarModelDict=%s" % curCarModelDict)
