### **我的案例：【由于不同的客户端，手机端和电脑端显示不一样,手机端可能需点击后才能动态加载】** ###

## ##

**注意：加上代码chrome\_options.add\_argument('headless') 后台运行，大部分是模拟手机端运行**

from selenium import webdriver
    from selenium.webdriver.support.wait import WebDriverWait
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support import expected_conditions as EC
    import time
    import logging
    
    executable_path=r"\app\libs\selenium\webdriver\chromedriver_match_83_version_browser_win.exe"
    chrome_options = webdriver.ChromeOptions()
    # 初始化谷歌浏览器的配置【必须加上】
    chrome_options.add_argument('headless')
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--disable-gpu')
    chrome_options.add_argument('--disable-dev-shm-usage')
    # 一定要把chrome_options配置来构造谷歌浏览器对象【必须匹配对应驱动的路径】
    web_chrome = webdriver.Chrome(executable_path=executable_path, options=chrome_options)
    web_chrome.get("https://aaxx.com")
    
    try:
        # 我这里使用By.CSS_SELECTOR选择器,有可以指定ID或class_name配置【更多参考By类】
        element = WebDriverWait(web_chrome, 2).until(
            EC.presence_of_element_located((By.CSS_SELECTOR, "#bdy")))
        menu_button = element.find_element_by_css_selector("button.ibtn.xxl.ripple-dark")
        menu_button.click()
        time.sleep(5)
        print(web_chrome.page_source)
        _elem_version = web_chrome.find_element_by_css_selector("cite.semver")
        _version = _elem_version.get_attribute("innerHTML")
        logging.warning(f"最新版本号为{_version}")
    finally:
        web_chrome.quit()
