找到数据了，直接请求网页，解析数据，保存数据

## 请求网页 ##

import requests
    url = 'https://xueqiu.com/service/v5/stock/screener/quote/list'
    response = requests.get(url=url, params=params, headers=headers, cookies=cookies)
    html_data = response.json()

## 解析数据 ##

data_list = html_data['data']['list']
    for i in data_list:
        dit = { }
        dit['股票代码'] = i['symbol']
        dit['股票名字'] = i['name']
        dit['当前价'] = i['current']
        dit['涨跌额'] = i['chg']
        dit['涨跌幅/%'] = i['percent']
        dit['年初至今/%'] = i['current_year_percent']
        dit['成交量'] = i['volume']
        dit['成交额'] = i['amount']
        dit['换手率/%'] = i['turnover_rate']
        dit['市盈率TTM'] = i['pe_ttm']
        dit['股息率/%'] = i['dividend_yield']
        dit['市值'] = i['market_capital']
        print(dit)

## 保存数据 ##

import csv
    f = open('股票数据.csv', mode='a', encoding='utf-8-sig', newline='')
    csv_writer = csv.DictWriter(f, fieldnames=['股票代码', '股票名字', '当前价', '涨跌额', '涨跌幅/%', '年初至今/%', '成交量', '成交额', '换手率/%', '市盈率TTM', '股息率/%', '市值'])
    csv_writer.writeheader()
    csv_writer.writerow(dit)
    f.close()
