selenium 不清楚缓存
时间: 2023-08-27 12:15:10 浏览: 198
Selenium 是一个用于自动化浏览器操作的工具,它提供了一些方法来操作浏览器的缓存。如果你想清除缓存,你可以使用 Selenium 的 `delete_all_cookies()` 方法来删除当前会话中所有的 cookie。这将清除浏览器中的所有缓存信息,包括 cookie、本地存储和会话存储。
你可以在执行其他操作之前调用 `delete_all_cookies()` 方法,以确保清除了缓存。以下是一个示例代码片段:
```python
from selenium import webdriver
# 创建一个浏览器实例
driver = webdriver.Chrome()
# 访问网页
driver.get("https://example.com")
# 删除所有的 cookie
driver.delete_all_cookies()
# 执行其他操作...
# 关闭浏览器实例
driver.quit()
```
请注意,这只会清除当前会话中的缓存,而不会影响到其他的浏览器实例或浏览器的默认设置。如果你需要更细粒度地控制缓存的清除,可以考虑使用其他方法,例如手动删除特定的 cookie 或执行 JavaScript 代码来清除缓存。

selenium 清理浏览器缓存
可以使用Selenium提供的options来设置浏览器清除缓存的行为,具体如下:
```python
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('--disable-application-cache')
options.add_argument('--disable-cache')
options.add_argument('--disable-offline-load-stale-cache')
options.add_argument('--disk-cache-size=0')
options.add_argument('--v8-cache-options=off')
driver = webdriver.Chrome(options=options)
```
这里使用了Chrome浏览器作为示例,其他浏览器的设置方法类似。其中,各个选项的意义如下:
- `--disable-application-cache`:禁用应用程序缓存。
- `--disable-cache`:禁用浏览器缓存。
- `--disable-offline-load-stale-cache`:禁用离线加载过期缓存。
- `--disk-cache-size=0`:设置磁盘缓存大小为0。
- `--v8-cache-options=off`:禁用V8缓存。
通过设置这些选项,可以清除浏览器缓存。
