Question

我正在一个项目上以获取http://www.jpmhkwarrants.com/en_hk/market-statistics/underlying/underlying-terms/code/1上的实时股价。我已经在网上搜索并尝试了几种获取价格的方法，但仍然失败。这是我的代码：

def getStockPrice():
      url = "http://www.jpmhkwarrants.com/zh_hk/market-statistics/underlying/underlying-terms/code/1" 
       r = urlopen(url)
      soup = BeautifulSoup(r.read(), 'lxmll)
      price = soup.find(id = "real_time_box").find({"span", "class":"price"})
      print(price)

输出为“无”。我知道价格写在上面的函数中，但我不知道如何获得价格。可以通过beautifulsoup还是其他模块来解决？

Answer 1

查看页面源代码，您将看到html

<div class="table detail">
    .....
    <div class="tl">即市走勢 <span class="description">前收市價</span>
    .....
    <td>買入價(延遲*)<span>82.15</span></td>

我们想要的span在索引2中，请选择

price = soup.select('.table.detail td span')[1]
print(price.text)

演示：

<script type="text/javascript" src="//cdn.datacamp.com/dcl-react.js.gz"></script>

<div data-datacamp-exercise data-lang="python">
	<code data-type="sample-code">
  from bs4 import BeautifulSoup
  from urllib.request import urlopen

  def getStockPrice():
        url = "http://www.jpmhkwarrants.com/zh_hk/market-statistics/underlying/underlying-terms/code/1" 
        r = urlopen(url)
        soup = BeautifulSoup(r.read(), 'html.parser')
        price = soup.select('.table.detail td span')[1]
        print(price.text)

  getStockPrice()
	</code>
</div>

如何使用BeautifulSoup在网站上获取实时股价？
