Selenium 常用配置信息

Chrome Driver 下载

Chromedriver所有版本下载链接：
https://chromedriver.storage.googleapis.com/index.html

注意版本对应关系，这里我用的是

版本 101.0.4951.41（正式版本） （64 位）

  • 1

下载对应的Chrome Driver 版本即可，版本号对应即可；最后一位不一样，也可正常使用；

Selenium Chrome Options 常见配置

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('disable-infobars')#谷歌不出现在被自动化工具控制
chrome_options.add_argument('--headless') # 无头浏览器设置, 使用无头容易出错
prefs = {"profile.managed_default_content_settings.images": 2}
chrome_options.add_experimental_option("prefs", prefs) # 不加载图片设置
chrome_options.add_argument('User-Agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.67 Safari/537.36"') # 谷歌文档提到需要加上这个属性来规避bug
chrome_options.add_argument('--disable-gpu') # 谷歌文档提到需要加上这个属性来规避bug
chrome_options.add_experimental_option('excludeSwitches', ['enable-automation'])
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_argument('log-level=3') 
chrome_options.add_argument("--start-maximized") # 最大化窗口
chrome_options.add_argument("--disable-cache")
chrome_options.add_argument("--no-sandbox"); 
chrome_options.add_argument("--disable-infobars")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument("--disable-browser-side-navigation")
chrome_options.add_argument("--disable-software-rasterizer")


chrome_options.binary_location=r"~/yourpath/chrome.exe"
desired_capabilities = copy.deepcopy(DesiredCapabilities.CHROME)
desired_capabilities["pageLoadStrategy"] = "none"
# chrome_options.add_argument(r'--user-data-dir=C:\Users\ADMINI~1\AppData\Local\Temp\scoped_dir11488_22853\Default') # 谷歌有时候大姨妈 需要加上这个 将其中的路径 设置成用户自己的数据目录
browser = webdriver.Chrome(
    chrome_options=chrome_options,
    executable_path=r"~/yourpath/chromedriver.exe",
    desired_capabilities = desired_capabilities
)

隐藏浏览器特征

其中stealth.min.js 文件可自行下载；

remove_webdriver_feature_js = os.path.join( os.path.dirname(__file__), 'stealth.min.js')
with open(remove_webdriver_feature_js) as fid:
    js = fid.read()
browser.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
    "source": js
})

代理配置

对于有批量下载需求的，可以使用相应的代理服务进行下载配置
