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添加argument:--allow-outdated-plugins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chrome_options.add_argument('--allow-outdated-plugins')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。
