在 Python 中自动下载适合 Selenium 的 chromedriver

Question

不幸的是，Chromedriver 总是特定于您安装的 Chrome 版本。因此，当您通过 PyInstaller 将 python 代码和 chromedriver 打包到 Windows 的可部署 .exe 文件中时，它在大多数情况下都不起作用，因为您将无法在 .exe 文件中拥有所有 chromedriver 版本。任何人都知道如何从网站自动下载正确的 chromedriver 的方法？如果没有，我会想出一个代码来下载 zip 文件并将其解压缩到临时文件。谢谢！

Answer 1

这是另一个解决方案，webdriver_manager不支持。此脚本将下载最新的 chrome 驱动程序版本。

import requests

import wget

import zipfile

import os

# get the latest chrome driver version number

url = 'https://chromedriver.storage.googleapis.com/LATEST_RELEASE'

response = requests.get(url)

version_number = response.text

# build the donwload url

download_url = "https://chromedriver.storage.googleapis.com/" + version_number +"/chromedriver_win32.zip"

# download the zip file using the url built above

latest_driver_zip = wget.download(download_url,'chromedriver.zip')

# extract the zip file

with zipfile.ZipFile(latest_driver_zip, 'r') as zip_ref:

    zip_ref.extractall() # you can specify the destination folder path here

# delete the zip file downloaded above

os.remove(latest_driver_zip)

Answer 2

这是 Python 的另一种方法 -

import chromedriver_autoinstaller

from selenium import webdriver

opt = webdriver.ChromeOptions()

opt.add_argument("--start-maximized")

chromedriver_autoinstaller.install()

driver = webdriver.Chrome(options=opt)

driver.get('https://stackoverflow.com/')

Webdriver Manager 会为你做这件事。请参考此链接https://pypi.org/project/webdriver-manager/

Answer 4

我有一个稍微漂亮一点的版本

它会检测到你的 chrome 版本，获取正确的驱动程序

def download_chromedriver():

    def get_latestversion(version):

        url = 'https://chromedriver.storage.googleapis.com/LATEST_RELEASE_' + str(version)

        response = requests.get(url)

        version_number = response.text

        return version_number

    def download(download_url, driver_binaryname, target_name):

        # download the zip file using the url built above

        latest_driver_zip = wget.download(download_url, out='./temp/chromedriver.zip')

        # extract the zip file

        with zipfile.ZipFile(latest_driver_zip, 'r') as zip_ref:

            zip_ref.extractall(path = './temp/') # you can specify the destination folder path here

        # delete the zip file downloaded above

        os.remove(latest_driver_zip)

        os.rename(driver_binaryname, target_name)

        os.chmod(target_name, 755)

    if os.name == 'nt':

        replies = os.popen(r'reg query "HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon" /v version').read()

        replies = replies.split('\n')

        for reply in replies:

            if 'version' in reply:

                reply = reply.rstrip()

                reply = reply.lstrip()

                tokens = re.split(r"\s+", reply)

                fullversion = tokens[len(tokens) - 1]

                tokens = fullversion.split('.')

                version = tokens[0]

                break

        target_name = './bin/chromedriver-win-' + version + '.exe'

        found = os.path.exists(target_name)

        if not found:

            version_number = get_latestversion(version)

            # build the donwload url

            download_url = "https://chromedriver.storage.googleapis.com/" + version_number +"/chromedriver_win32.zip"

            download(download_url, './temp/chromedriver.exe', target_name)

    elif os.name == 'posix':

        reply = os.popen(r'chromium --version').read()

        if reply != '':

            reply = reply.rstrip()

            reply = reply.lstrip()

            tokens = re.split(r"\s+", reply)

            fullversion = tokens[1]

            tokens = fullversion.split('.')

            version = tokens[0]

        else:

            reply = os.popen(r'google-chrome --version').read()

            reply = reply.rstrip()

            reply = reply.lstrip()

            tokens = re.split(r"\s+", reply)

            fullversion = tokens[2]

            tokens = fullversion.split('.')

            version = tokens[0]

        target_name = './bin/chromedriver-linux-' + version

        print('new chrome driver at ' + target_name)

        found = os.path.exists(target_name)

        if not found:

            version_number = get_latestversion(version)

            download_url = "https://chromedriver.storage.googleapis.com/" + version_number +"/chromedriver_linux64.zip"

            download(download_url, './temp/chromedriver', target_name) 

 

Answer 5

截至 2021 年 8 月，这是状态：-

chromedriver-自动安装程序

自动下载并安装支持当前安装的 chrome 版本的 chromedriver。此安装程序支持 Linux、MacOS 和 Windows 操作系统。

安装

pip install chromedriver-autoinstaller

用法

Just type import chromedriver_autoinstaller in the module you want to use chromedriver.

例子

from selenium import webdriver

import chromedriver_autoinstaller

chromedriver_autoinstaller.install()  # Check if the current version of chromedriver exists

                                      # and if it doesn't exist, download it automatically,

                                      # then add chromedriver to path

driver = webdriver.Chrome()

driver.get("http://www.python.org")

assert "Python" in driver.title
