Python的selenium闪退和谷歌浏览器版本或驱动不兼容问题解决方法以及基本配置语法（Selenium和Google版本及GoogleDriver版本对应）_selenium4和chrome驱动版本

一、前言

Python的selenium库有各种的版本，谷歌浏览器也有各种版本和驱动，在这里就是下载一个专门为了应用selenium自动化下载的驱动和谷歌版本。

（一）下载专门的谷歌浏览器和下载对应驱动

这个网页就是下载的===>>>谷歌浏览器和对应驱动下载地址

1.去到网页选择对应的版本

如果你是Mac系统就选Mac，如果是Linux就选Linux，我这里只以Windows系统为例，如下图所示

2.点击对应版本下载

选择到合适的版本然后点击进去，点version和position都可以进入（反正同一行进入的页面都是一样的）

找到以下图片对应的位置，点击下载浏览器和驱动即可，其他的系统版本也是一样的操作（Mac或Linux）

3.下载完成后解压到选定的目录

下载完成后会有对应的压缩包，解压到指定位置就行，我这里是解压完成后的效果，如下图所示

到这里有些铁汁就要问了，“你这不是和下载谷歌对应驱动和版本一样的吗？有什么区别？”，区别可大了，主要有两点： 1. 这里下载的谷歌浏览器是相当于一个工具，并不是我们主流谷歌浏览器，我们可以把它当成一个专门用来做自动化的工具窗口，并且比常见下载的谷歌浏览器的好处就在于它不会自动更新，并且你可以任意配置且不会影响到自己的谷歌浏览器； 2. 这里方便了管理和卸载，直接删除文件夹就可以彻底清除，不会影响到正常安装等问题，并且下载方便，谷歌浏览器和对应的驱动版本都在一起，方便下载。效果图如下。

（二）在需要使用的项目中去引用

在上面我们已经下载好了对应谷歌浏览器和对应的版本驱动，这里我们在项目中直接引用即可
，如下所示。

先导项，创建一个stealth.min.js文件

在里面填写如下内容，然后保存即可，且记住路径

1.创建 userConfig.py文件

这里我在项目中创建了一个 userConfig.py 文件，当然你们也可以不这么创建，我这里只是方便管理，如果不想用这种方法，直接引入路径就可以了

2.创建 extension.py文件

然后创建一个 extension.py 文件，如下图所示，用随机代理和不用的方法我都会写上代码。

（1）用了随机代理和无头模式

无头模式就是说不打开浏览器的界面，在后台运行，如果不设置无头模式，就是普通的我们能看到浏览器在自动运行的界面

因为下面用了随机代理，所以需要下载随机代理的库

pip install fake_useragent

如果下载太慢了，直接清华源下载地址方法===>>>Python清华源下载加速

from selenium import webdriver
# 导入随机假代理的库，需要下载
from fake_useragent import UserAgent
from userConfig import GoogleDriver, GoogleExe, StJS


def selenium_driver():
    # 浏览器配置对象
    options = webdriver.ChromeOptions()
    # 禁用自动化栏
    options.add_experimental_option('excludeSwitches', ['enable-automation'])
    # 屏蔽密码保持提示框
    prefs = {'credentials_enable_service': False, 'profile.password_manager_enabled': False}
    options.add_experimental_option('prefs', prefs)
    # 设置无头模式 因为有反爬虫序列，需要设置useAge
    options.add_argument('--headless')
    options.add_argument('--no-sandbox')
    options.add_argument('--disable-dev-shm-usage')
    """ 这个是用了随机代理"""
    options.add_argument(f"--user-agent='{UserAgent.random}'") #用随机代理
    # 反爬虫特征处理
    options.add_argument('--disable-blink-features=AutomationControlled')
    # 本地下载的谷歌浏览器地址，如果没有创建userConfig.py,请用下面的方法
    # options.binary_location = r"D:\python\MyProgramDesign\Application\GooGleMyPython\chrome-win\chrome.exe"
    # 如果用了上面的方法，就把下面的注释了
    options.binary_location = GoogleExe
    # 驱动定义,如果没有用userConfig.py,请用下面的方法
    # drivers = webdriver.Chrome(executable_path=r"D:\python\MyProgramDesign\Application\GooGleMyPython\chromedriver_win32\chromedriver.exe", options=options)
    # 如果用了上面的方法，请把下面注释了！
    drivers = webdriver.Chrome(executable_path=GoogleDriver, options=options)
    # 打开反爬js文件
    f = open(StJS, mode='r', encoding='utf-8').read()
    # 移除爬虫特征
    drivers.execute_cdp_cmd('Page.addScriptToEvaluateOnNewDocument', {'source': f})

    return drivers

3.在主函数里面引用驱动文件

我们导入extension文件，然后在引用驱动就好啦！到这里我们就学会如何去使用完整的selenium的过程，如果需要练习问卷星自动答题，请移步===>>>问卷星自动答题

代码如下，以下是一个简单的事例，请根据需要修改

import extension

def baidu(driver):
	userUrl = 'https://www.baidu.com'
	# 打开百度地址
    driver.get(userUrl)  
    # 五秒后自动关闭网页和关闭驱动
    time.sleep(5)
    driver.close()
    driver.quit()

if __name__ == '__main__':
    # 调用驱动
    drivers = extension.selenium_driver()
    # 用驱动打开百度
    baidu(drivers)

二、拓展selenium基本配置语法

通常我们的 options.add_argument(‘放置的语法’) ，
如下使用方法

# 无头模式
options.add_argument('--headless')
# 彻底停用沙箱
options.add_argument('--no-sandbox')

三、总结

selenium是我们常用的爬虫自动化库，相应的还有Scrapy爬虫框架等，如果需要我出Scrapy框架教学的请在评论区说一下或者私信我，那么以上就是selenium入门方法了，如果各位看官觉得有意义，请给我点个赞把！谢谢啦！
