问题描述

我正在尝试从雅虎财经中抓取数据，但我只能从此链接的统计页面上的某些表格中获取数据https://finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL.我能够从顶部表和左侧表中获取数据，但我无法弄清楚为什么以下程序不会从具有 Beta(每月 5 年)、52 周更改、上次拆分因子等值的右侧表中抓取和上次分割日期

I am trying to scrape data from yahoo finance, but I am only able to get data from certain tables on the statistics page at this link https://finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL. I am able to get data from the top table and the left tables, but I can't figure out why the following program won't scrape from the right tables with values like Beta (5Y Monthly), 52 Week Change,Last Split Factor and Last Split Date

stockStatDict = {}

stockSymbol = 'AAPL'
URL = 'https://finance.yahoo.com/quote/'+ stockSymbol + '/key-statistics?p=' + stockSymbol
page = requests.get(URL, headers=headers, timeout=5)


soup = BeautifulSoup(page.content, 'html.parser')

# Find all tables on the page
stock_data = soup.find_all('table')

# stock_data will contain multiple tables, next we examine each table one by one
for table in stock_data:

    # Scrape all table rows into variable trs
    trs = table.find_all('tr')


    for tr in trs:
        print('tr: ', tr)
        print()
        # Scrape all table data tags into variable tds
        tds = tr.find_all('td')
        print('tds: ', tds)
        print()
        print()

        if len(tds) > 0:
            # Index 0 of tds will contain the measurement
            # Index 1 of tds will contain the value
            # Insert measurement and value into stockDict
            stockStatDict[tds[0].get_text()] = [tds[1].get_text()]

stock_stat_df = pd.DataFrame(data=stockStatDict)
print(stock_stat_df.head())
print(stock_stat_df.info())

知道为什么这段代码不检索这些字段和值吗?

Any idea why this code isn't retrieving those fields and values?

推荐答案

要从 Yahoo 服务器获得正确的响应，请设置 User-Agent HTTP 标头:

To get correct response from the Yahoo server, set User-Agent HTTP header:

import requests
from bs4 import BeautifulSoup


url = "https://finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL"

headers = {
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0"
}

soup = BeautifulSoup(requests.get(url, headers=headers).content, "html.parser")

for t in soup.select("table"):
    for tr in t.select("tr:has(td)"):
        for sup in tr.select("sup"):
            sup.extract()
        tds = [td.get_text(strip=True) for td in tr.select("td")]
        if len(tds) == 2:
            print("{:<50} {}".format(*tds))

打印:
