我想从“https://www.bseindia.com/corporates/Forth_Results.aspx”下载 Results.csv 我想基本上以数据帧格式获取数据。我使用下面的代码下载了文件，但它得到了一些错误数据。import requestsimport pandas as pdbse_url = 'https://www.bseindia.com/corporates/Forth_Results.aspx'r = requests.get(bse_url)file_name = Results.csvwith open(file_name, 'wb') as f: for chunk in r.iter_content(): f.write(chunk) f.flush()

您可以在 selenium 的帮助下执行此操作，请按照以下步骤操作：
第 1 步：下载 chrome 的网络驱动程序：
首先检查您的 chrome 版本（浏览器的菜单（三个垂直点）-> 帮助 -> 关于 Google Chrome
第二步：根据你的chrome浏览器版本下载驱动（我的是81.0.4044.138）
第 3 步：下载后解压缩文件并将chromedriver.exe放在脚本所在的目录中。
步骤4：pip install selenium
现在使用下面的代码：
from selenium import webdriver
import os
import pandas as pd
#your website url
site = 'https://www.bseindia.com/corporates/Forth_Results.aspx'
#your driver path
driver = webdriver.Chrome(executable_path = 'chromedriver.exe')
#passing website url
driver.get(site)
#wait until whole sites load
time.sleep(5)
#click download icon using xpath
driver.find_element_by_xpath("/html/body/div[1]/form/div[4]/div/div[2]/div/div/div[2]/a/i").click()
#closing browser
driver.close()
#reading Results.csv from defalut download directory
df = pd.read_csv("c:/users/viupadhy/downloads/Results.csv")
df
输出：
