嗨,我正在尝试使用Beautiful Soup解析html表.该表看起来像这样:

<table width=100% border=1 cellpadding=0 cellspacing=0 bgcolor=#e0e0cc>
 <tr>
  <td width=12% height=1 align=center valign=middle  bgcolor=#e0e0cc bordercolorlight=#000000 bordercolordark=white> <b><font face="Verdana" size=1><a href="http://www.dailystocks.com/" alt="DailyStocks.com" title="Home">Home</a></font></b></td>
 </tr>
</table>
<table width="100%" border="0" cellpadding="1" cellspacing="1">
  <tr class="odd"><td class="left"><a href="whatever">ABX</a></td><td class="left">Barrick Gold Corp.</td><td>55.95</td><td>55.18</td><td class="up">+0.70</td><td>11040601</td><td>70.28%</td><td><center>&nbsp;<a href="whatever" class="bcQLink">&nbsp;Q&nbsp;</a>&nbsp;<a href="chart.asp?sym=ABX&code=XDAILY" class="bcQLink">&nbsp;C&nbsp;</a>&nbsp;<a href="texpert.asp?sym=ABX&code=XDAILY" class="bcQLink">&nbsp;O&nbsp;</a>&nbsp;</center></td></tr>
 </table>

我想从第二个表中获取信息,到目前为止我尝试了这段代码:

html = file("whatever.html")
soup = BeautifulSoup(html)
t = soup.find(id='table')
dat = [ map(str, row.findAll("td")) for row in t.findAll("tr") ]

这似乎不起作用,任何帮助将不胜感激,谢谢

是从休息端点调用 puppeteer 的适当方法吗？

路由.js

const express = require('express');

const PuppeteerController = require('../controllers/puppetter');

const router = express.Router();

router.post('/getPath', PuppeteerController.getPage);

控制器.js

async getPage(req, res) {
   try {
    let resp = await pageScanner.getPageContent(url);
    return res.status(200).send(resp);
   }
   catch(e) {
      return res.status(400).send({
        error: 'not-found'
      });
   }
}

扫描仪.js

async getPageContent(url) {
   try {
      const browser = await puppeteer.launch({
        args: [
          '--no-sandbox',
          '--disable-setuid-sandbox',
          '--disable-dev-shm-usage',
          '--disable-accelerated-2d-canvas',
          '--disable-gpu'
        ]
      });
      const page = await browser.newPage();
      await page.setViewport({ width: 800, height: 600 });
      await page.goto(url);
      await page.waitFor(1000);
      const pageContent …
