如何在運行程序時保持 Selenium Webdriver chrome 瀏覽器打開？

Question

我正在使用 selenium 從體育網站提取數據。 我希望我的 Chrome 瀏覽器在關閉之前保持打開狀態。 但是我的程序在 3-4 秒后關閉了 Chrome window。 任何有關尋找解決方案的幫助將不勝感激。

這是我的代碼：

from selenium import webdriver
from selenium.webdriver.common.keys import  Keys
import pandas as pd

print('\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 dataframe


driver = 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 list
players_list = []
for p in range(len(players)):
    players_list.append(players[p].text)

#to get the salaries into a list
salaries_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 together
temp_df = pd.DataFrame(data_tuples, columns=['Player','Salary']) # creates dataframe of each tuple in list
temp_df['Year'] = page_num   # adds season beginning year to each dataframe
df = df.append(temp_df)  #appends to master dataframe


driver.close()

Answer 1

它關閉是因為您在最后添加了driver.close() 。 只需刪除該行，瀏覽器將永遠保持打開狀態。 如果你想在一段時間后關閉它，那么你可以在driver.close()之前添加time.sleep ，如下所示：

import time

# Your code

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

driver.close()

Answer 2

在您的 WebDriver 中（當您實例化它時），您可以將以下內容添加到您的 Chrome 選項中

chrome_options.add_experimental_option("detach", True)

完成此操作后，通過命令終端（Windows 中的命令提示符）運行它，它不應關閉

主程序 - 供參考

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()

driver.close() 將關閉您的瀏覽器。 如果您希望瀏覽器仍然打開，只需將其刪除
