从纳斯达克刮表(初学者)

Question

url = https://www.nasdaqtrader.com/trader.aspx?id=TradeHalts

我正试着从上面的网址抓起桌子。然而，当我试图用漂亮的汤找到桌子时，我失败了。我只是得到了一个空的列表。

请帮帮忙。

谢谢

import requests

from bs4 import BeautifulSoup

page = requests.get("https://www.nasdaqtrader.com/trader.aspx?id=TradeHalts")

soup = BeautifulSoup(page.text, "lxml")


item = soup.find(class_="genTable")


print(item)

Answer 1

我认为代码是非常清楚的，但是如果您有任何问题，请随意提问。

headers = {"Referer": "https://www.nasdaqtrader.com/trader.aspx?id=TradeHalts"}
data = {"id":2,"method":"BL_TradeHalt.GetTradeHalts","params":"[]","version":"1.1"}
url = "https://www.nasdaqtrader.com/RPCHandler.axd"
req = requests.post(url, json=data, headers=headers)
result = req.json()['result']
soup = BeautifulSoup(result, 'html.parser')
table = soup.find('table')
