Selenium+Chrome浏览器自动加载Flash
在自动化脚本编写过程中,遇到一些网页需要使用Flash插件,但是通过Selenium启动的浏览器不能默认对网页启动Flash,需要在chrome://settings/content/siteDetails?site={url}网页进行设置。
添加argument:–allow-outdated-plugins
from selenium import webdriver from selenium.webdriver.chrome.options import Options chrome_options = Options() chrome_options.add_argument(--allow-outdated-plugins) driver = webdriver.Chrome(options=chrome_options) driver.get(http://testops:81/phpwind/register.php#breadCrumb)
参数作用:允许使用旧版本的插件。 注意:旧版本的插件可能有漏洞,不要访问来历不明的网站。
允许Falsh方法
from urllib.parse import quote_plus as url_quoteplus from urllib.parse import urlsplit from selenium.webdriver.common.by import By as WebBy from selenium.webdriver.support.ui import Select as WebSelect def allow_flash(driver, url): def _base_url(url): if url.find("://") == -1: url = "http://{}".format(url) urls = urlsplit(url) return "{}://{}".format(urls.scheme, urls.netloc) def _shadow_root(driver, element): return driver.execute_script("return arguments[0].shadowRoot", element) base_url = _base_url(url) driver.get("chrome://settings/content/siteDetails?site={}".format(url_quoteplus(base_url))) root1 = driver.find_element(WebBy.TAG_NAME, "settings-ui") shadow_root1 = _shadow_root(driver, root1) root2 = shadow_root1.find_element(WebBy.ID, "container") root3 = root2.find_element(WebBy.ID, "main") shadow_root3 = _shadow_root(driver, root3) root4 = shadow_root3.find_element(WebBy.CLASS_NAME, "showing-subpage") shadow_root4 = _shadow_root(driver, root4) root5 = shadow_root4.find_element(WebBy.ID, "advancedPage") root6 = root5.find_element(WebBy.TAG_NAME, "settings-privacy-page") shadow_root6 = _shadow_root(driver, root6) root7 = shadow_root6.find_element(WebBy.ID, "pages") root8 = root7.find_element(WebBy.TAG_NAME, "settings-subpage") root9 = root8.find_element(WebBy.TAG_NAME, "site-details") shadow_root9 = _shadow_root(driver, root9) root10 = shadow_root9.find_element(WebBy.ID, "plugins") # Flash shadow_root10 = _shadow_root(driver, root10) root11 = shadow_root10.find_element(WebBy.ID, "permission") WebSelect(root11).select_by_value("allow")
设置driver允许Flash
allow_flash(driver,"http://testops:81")
解释
shadow root elements
该种类elements下的元素,不能通过selenium方法直接定位,需要JS的方法:element.shadowRoot找到元素
版本
在Chrome73.0.3683.86上测试成功,旧版本的Chrome不一定需要这么麻烦,添加一个argument也许就可以了。
