selenium常用配置

from selenium import webdriver
import time
from selenium.webdriver.chrome.options import Options  # 配置的包

path = 'chromedriver.exe'

# 配置相关
chrome_options = Options()  # 可以理解为配置对象
# 1. 配置不加载图片
# prefs = {"profile.managed_default_content_settings.images": 2}
# chrome_options.add_experimental_option("prefs", prefs)

# 2. 无界面
# chrome_options.add_argument('--headless')
# chrome_options.add_argument('--disable-gpu')

# 3. 移动端配置
# WIDTH = 600
# HEIGHT = 800
# PIXEL_RATIO = 3.0
# UA = 'Mozilla/5.0 (iPhone; CPU iPhone OS 13_2_3 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0.3 Mobile/15E148 Safari/604.1'
# mobileEmulation = {"deviceMetrics": {"width": WIDTH, "height": HEIGHT, "pixelRatio": PIXEL_RATIO}, "userAgent": UA}
# chrome_options.add_experimental_option('mobileEmulation', mobileEmulation)

# 4. 操作已打开的浏览器
# chrome.exe --remote-debugging-port=9222 --user-data-dir="C:selenumAutomationProfile"
chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")

browser = webdriver.Chrome(path, options=chrome_options)
browser.get('http://www.netbian.com/')
time.sleep(15)
browser.quit()
