selenium如何清空Chrome缓存

在Selenium中，你可以使用ChromeOptions类的addArguments方法来添加启动参数，其中包括清空Chrome浏览器缓存的选项。具体操作如下所示：

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--disable-application-cache')
options.add_argument('--disable-gpu-shader-disk-cache')
options.add_argument('--disable-gpu-program-cache')
options.add_argument('--disable-reading-from-canvas')
options.add_argument('--disable-extensions')
driver = webdriver.Chrome(options=options)

在上述代码中，我们使用ChromeOptions类添加了一些启动参数，其中包括禁用应用程序缓存、禁用GPU着色器磁盘缓存、禁用GPU程序缓存、禁用从画布读取等。这些选项的组合可以有效地清空Chrome浏览器中的缓存。

selenium 清理浏览器缓存

在使用 Selenium 进行自动化测试时，清理浏览器缓存可以避免测试数据因为缓存而出现错误。以下是清理 Chrome 浏览器缓存的代码示例：

from selenium import webdriver

# 创建 Chrome 浏览器实例
options = webdriver.ChromeOptions()
driver = webdriver.Chrome(chrome_options=options)

# 打开浏览器设置页面
driver.get('chrome://settings/clearBrowserData')

# 等待浏览器设置页面加载完成
driver.implicitly_wait(10)

# 选择清理缓存选项
driver.find_element_by_css_selector('settings-ui').send_keys(Keys.TAB * 3 + Keys.ENTER)
time.sleep(2)

# 关闭浏览器
driver.quit()

该代码会打开 Chrome 浏览器的设置页面，选择清理缓存选项并执行清理操作，最后关闭浏览器。你可以根据自己的需求选择适合的浏览器和清理方式。
