踩到的坑一：
中文乱码，解决方法：
centos:
yum groupinstall fonts
ubuntu:
sudo apt-get install ttf-wqy-microhei ttf-wqy-zenhei xfonts-wqy
踩到的坑二：
不能截图，抛time out异常
selenium.common.exceptions.TimeoutException: Message: timeout: Timed out receiving message from renderer: 10.000
解决方法：
options = webdriver.ChromeOptions()
options.add_argument("--headless")
options.add_argument("start-maximized")
options.add_argument("enable-automation")
options.add_argument("--no-sandbox")
options.add_argument("--disable-infobars")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--disable-browser-side-navigation")
options.add_argument("--disable-gpu")
driver = webdriver.Chrome(chrome_options=options)
driver.set_window_size(1024, 768)
driver.get_screenshot_as_file(STATIC_FOLDER + home_img_url)
driver.close()
