我的解答思路和尝试过的方法

我想要达到的结果

首先用
css选择器定位到下载按钮然后click点击

Chrome 浏览器上的下载按钮是浏览器自身的，是无法定位的
下载的是PDF文件，可以通过设置浏览器的配置参数，实现预览PDF的时候，就自动下载PDF文件了。需要在初始化浏览器时加参数

        chrome_options = Options()
        chrome_options.add_argument('--headless')
        prefs = {'profile.default_content_settings.popups': 0, 'download.default_directory': 'd:\\'}
        chrome_options.add_experimental_option('prefs', prefs,)
        chrome_options.add_argument("--window-size=1920,1080")
        self.browser = webdriver.Chrome(options=chrome_options)
        # self.browser = webdriver.Chrome()
        self.browser.get("下载的地址")
        self.browser.maximize_window()
        self.bs = Base(self.browser)
        bdd = self.browser.get_log('browser')
