# python获取Chrome版本并更新匹配的chromedriver

在使用selenium库，经常会因为chromedriver的版本问题出现报错

```
import re, zipfile, requests, os
from selenium import webdriver
from selenium.webdriver.chrome.service import Service

class driver(object):

def unzip_file(self, src_file, dest_dir, *password):
        if password:
            password = password.encode()
        zf = zipfile.ZipFile(src_file)
        try:
            zf.extractall(path=dest_dir, pwd=password)
        except RuntimeError as e:
            print(e)
        zf.close()

def chrome_driver(self):
        root_path = os.path.abspath(os.path.dirname(__file__)).replace("test", "")  # 获取项目根路径
        i = 1
        driver = None
        while (True):
            if i == 3: break
            try:
                service = Service(root_path + "\chromedriver.exe")
                options = webdriver.ChromeOptions()
                options.add_argument('--no-sandbox')  # 解决DevToolsActivePort文件不存在的报错
                options.add_argument('--disable-dev-shm-usage')
                options.add_argument('--disable-gpu')  # 谷歌文档提到需要加上这个属性来规避bug
                options.add_argument('blink-settings=imagesEnabled=false')  # 不加载图片, 提升速度
                options.add_argument('--headless')  # 浏览器不提供可视化页面. linux下如果系统不支持可视化不加这条会启动失败
                driver = webdriver.Chrome(service=service, options=options)
                break
            except Exception as msg:
                print(1)
                reg = "Current browser version is.+with"
                chrome_version = re.search(reg, str(msg)).group().replace("Current browser version is ", "").replace(
                    " with",
                    "")
                file_path = root_path + '\catch\\'
                if not os.path.exists(file_path):
                    os.makedirs(file_path)
                chrome_version_list = chrome_version.split('.')
                # print("Chrome Version:" + chrome_version)
                v3 = requests.get('http://chromedriver.storage.googleapis.com/').text.split(
                    f'<Key>{chrome_version_list[0]}.{chrome_version_list[1]}.{chrome_version_list[2]}.', 1)[1].split(
                    '/chromedriver_linux64.zip', 1)[0]
                file_name = 'chromedriver_' + chrome_version_list[0] + '_' + chrome_version_list[1] + '_' + \

                downloadurl = 'http://chromedriver.storage.googleapis.com/' + chrome_version_list[0] + '.' + \
                              chrome_version_list[1] + '.' + chrome_version_list[
                                  2] + '.' + v3 + '/chromedriver_win32.zip'

print(downloadurl)
                response = requests.get(downloadurl)
                # 保存ChromeDriver到当前项目路径下的/catch目录下
                with open(file_path+file_name, 'wb') as f:
                    f.write(response.content)
                # 解压zip文件
                self.unzip_file(file_path+file_name, root_path)
        i += 1
        return driver

driver = driver().chrome_driver()
driver.get('https://www.baidu.com')
driver.quit()
print(driver.page_source)
