我正在尝试解析下面的网页，以获取目前在交易所创下历史新高或低点的股票名称。
https://www.bseindia.com/markets/equity/EQReports/HighLow.html?Flag=H#
然而，当我用美汤下载网页并查看数据时，只有一半的股票出现，这是因为 该页面有 2 页，因此使用上述方法，一页上有 25 个股票，另一页有 25 个股票，我只能解析第一页， 如果我点击第二页，网址也相同，请帮助我如何解决这个问题？

该站点有一个 api 端点，它以漂亮的 json 格式将数据返回给您。您可以获得该 json 格式的响应，然后对其进行规范化以创建一个表。现在，当它执行此操作时，它会返回 2 个表，所以我不确定您是否想要第二个表。如果没有，我将它们分别存储，然后将它们附加到一起。
import requests
from pandas.io.json import json_normalize
url = 'https://api.bseindia.com/BseIndiaAPI/api/MktHighLowData/w?Grpcode=&HLflag=H&indexcode=&scripcode='
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36'}
payload = {
'Grpcode':'',
'HLflag': 'H',
'indexcode':'' ,
'scripcode':'' }
jsonObj = requests.get(url, headers=headers, params=payload).json()
df_table = json_normalize(jsonObj['Table'])
df_table1 = json_normalize(jsonObj['Table1'])
df = df_table.append(df_table1)
输出：
print (df)
