如何在运行程序时保持 Selenium Webdriver chrome 浏览器打开？

Question

我正在使用硒从体育网站提取数据。我希望 Chrome 浏览器保持打开状态，直到我将其关闭。但我的程序在 3-4 秒后关闭 Chrome 窗口。任何有关寻找解决方案的帮助将不胜感激。这是我的代码：from selenium import webdriverfrom selenium.webdriver.common.keys import  Keysimport pandas as pdprint('\nWelcome to Arsenal FC players payroll page\n')page_num = input('Enter the year for payroll data (2011-2020): ')df = pd.DataFrame(columns = ['Player', 'Salary', 'Year']) #creates a master dataframedriver = webdriver.Chrome('/Users/mahtabkhan/Documents/chromedriver')if(page_num != 2020):    url = 'https://www.spotrac.com/epl/arsenal-fc/payroll/' + page_num + '/'else:    url = 'https://www.spotrac.com/epl/arsenal-fc/payroll/' driver.get(url)players = driver.find_elements_by_xpath('//td[@class="player"]')salaries = driver.find_elements_by_xpath('//td[@class="cap info"]')#to get the text of each player into a listplayers_list = []for p in range(len(players)):    players_list.append(players[p].text)#to get the salaries into a listsalaries_list = []for s in range(len(salaries)):    salaries_list.append(salaries[s].text)  data_tuples = list(zip(players_list[1:],salaries_list[1:])) # list of each players name and salary paired togethertemp_df = pd.DataFrame(data_tuples, columns=['Player','Salary']) # creates dataframe of each tuple in listtemp_df['Year'] = page_num   # adds season beginning year to each dataframedf = df.append(temp_df)  #appends to master dataframedriver.close()

Answer 1

在您的 WebDriver 中（当您实例化它时），您可以将以下内容添加到 Chrome 选项中

chrome_options.add_experimental_option("detach", True)

完成此操作后，通过命令终端（Windows 中的命令提示符）运行它，它应该不会关闭

主程序 - 供参考

from selenium import webdriver

def get_chrome_driver():

    """This sets up our Chrome Driver and returns it as an object"""

    path_to_chrome = "F:\Selenium_Drivers\Windows_Chrome85_Driver\chromedriver.exe"

    chrome_options = webdriver.ChromeOptions() 

    

    # Keeps the browser open

    chrome_options.add_experimental_option("detach", True)

    

    # Browser is displayed in a custom window size

    chrome_options.add_argument("window-size=1500,1000")

    

    # Removes the "This is being controlled by automation" alert / notification

    chrome_options.add_experimental_option("excludeSwitches", ['enable-automation'])

    

    return webdriver.Chrome(executable_path = path_to_chrome,

                            options = chrome_options)

# Gets our chrome driver and opens our site

chrome_driver = get_chrome_driver()

chrome_driver.get("https://www.google.com/")

print('The browser should not close after you see this message')

chrome_driver.service.stop()

Answer 3

driver.close()它关闭是因为您在末尾添加了内容。只要删除该行，浏览器就会永远保持打开状态。如果你想在一段时间后关闭它，那么你可以像这样添加time.sleep之前：driver.close()

import time

# Your code

time.sleep(60) #Stays open for 60 seconds (which is 1 min)

driver.close()

Answer 4

driver.close() 将关闭您的浏览器。如果您希望浏览器仍然打开，只需将其删除
