Selenium + chromeDriver + Python3 完成 Flash 播放

环境要求：selenium chromeDriver Python3

问题

chrome 无头浏览器无法自动加载 Flash

解决办法

参考了 allow-flash-content-in-chrome-69-running-via-chromedriver 的回答，直接修改 Chrome 的设置 chrome://settings/content/siteDetails?site= 里面的 Flash 设置，修改为 Allow

最后

不能使用无界面模式，不能设置 handless 参数 options.add_argument('--headless')。否则无法直接修改 Chrome 的设置。
