想通过使用BeautifulSoup从雅虎财务中检索股票公司名称

Question

我试图使用BeautifulSoup废弃股票公司名称，但结果“IndexError：list index out of range”出现。

贝洛斯是我的代码

from bs4 import BeautifulSoup
list = ['BABA', 'APPL']
stockname = []
for i in range(len(list)):
      stock_company = "https://finance.yahoo.com/quote/"+list[i]
      soup = BeautifulSoup(requests.get(stock_company).text,"html.parser").select('h1')[0].text.strip()[10:]
      stockname.append(soup)                                         
stockname

Answer 1

您可以从“https://finance.yahoo.com/quote/ {ticker}”URL中删除公司名称，但是所有其他数据（如数量和价格）都是通过Ajax从“https://query1.finance.yahoo.com”加载的。此示例将加载公司名称和收盘价：

import requests
from bs4 import BeautifulSoup
import json
from pprint import pprint

tickers = ['BABA', 'AAPL']
stockname = []
for ticker in tickers:
    stock_company = f"https://finance.yahoo.com/quote/{ticker}"
    soup = BeautifulSoup(requests.get(stock_company).text, "html.parser")
    name = soup.h1.text.split('-')[1].strip()
    ticker_data_url = f"https://query1.finance.yahoo.com/v8/finance/chart/{ticker}?region=US&lang=en-US&includePrePost=false&interval=2m&range=1d&corsDomain=finance.yahoo.com&.tsrc=finance"
    ticker_data = json.loads(requests.get(ticker_data_url).text)
    price = ticker_data['chart']['result'][0]['meta']['previousClose']
    if name:
        stockname.append( [ticker, name, price] )

pprint(stockname, width=60)

将打印：

[['BABA', 'Alibaba Group Holding Limited', 187.25],
 ['AAPL', 'Apple Inc.', 191.44]]

Apple有自动收录机AAPL，而不是APPL。

Answer 2

为什么重新发明轮子？试试yahoo_finance模块：

>>> from yahoo_finance import Share
>>> yahoo = Share('YHOO')
>>> print yahoo.get_open()
'36.60'
>>> print yahoo.get_price()
'36.84'
>>> print yahoo.get_trade_datetime()
'2014-02-05 20:50:00 UTC+0000'
