import os from selenium import webdriver from selenium.webdriver.chrome.options import Options

检测是否已经打开了浏览器

def check_browser(): options = Options() options.add_experimental_option('debuggerAddress', '127.0.0.1:9527') try: browser = webdriver.Chrome(options=options) browser.quit() return True except: return False

使用CMD命令打开一个新的浏览器

if name == 'main': if not check_browser(): os.system(r'start chrome --remote-debugging-port=9527 --user-data-dir='D:\评阅用'') # 获取刚才打开的浏览器 options = Options() options.add_experimental_option('debuggerAddress', '127.0.0.1:9527') browser = webdriver.Chrome(options=options) browser.get('https://menhu.pt.ouchn.cn/site/ouchnPc/index') print(browser.title)
