I have tried opening the link and taking the screenshot using both R and python and it does take the screenshot without opening browser. But the video screenshot is black with an error which I don't want.

推荐答案

您可以使用 chrome 的无头模式.在调用 chrome 驱动程序之前，创建选项的选项对象，然后作为参数发送给驱动程序.然后你可以在后端运行这个代码，即使是一些没有任何屏幕的环境，包括 docker 容器.但要小心设置窗口大小.这会影响您的屏幕截图结果.

You can use headless mode of chrome. Before call driver of chrome, create option object of option then send to driver as argument. Then you can run this code in backend even some environment without any screen include docker container. But be careful to set window size. This will affect your screenshot result.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options() #
chrome_options.add_argument('--headless')
chrome_options.add_argument("--window-size=1920x1080")
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=chrome_driver)
driver.get_screenshot_as_file("capture.png")
