遍历翻页功能测试时，出现报错：
Message: element is not attached to the page document
官方给出解释如下：
The element has been deleted entirely.
The element is no longer attached to the DOM.
检查发现点击翻页会调用ajax请求，在请求未完成时，评论列表元素过期，无法获取到元素
最开始想着加个等待时间WebDriverWait就好了（封装方法里都包含显示等待），看来是我太天真，最后想明白了其实在操作点击页码之后，ajax没有立即加载完成，所以此时元素还是存在的，但ajax响应后，元素就过期了，原因是点击页码操作首先响应ajax请求，ajax请求响应成功后元素过期，下面三个请求响应元素再次出现。
然后试着强等 time.sleep(1)，发现不报错了，不过这种方式不稳定，万一网络不好或者服务器压力过大，等一秒也不够啊，那等30秒，每次都等30秒么？那也不现实，那就没有其他方法类似于WebDriverWait么？
于是我换种方式，能不能获取浏览器所有请求呢，通过各种百度，找到了Selenium拦截页面Ajax请求及响应数据的方法（参考：https://www.likeinlove.com/info/104.html）
修改代码如下，妥妥的解决了，哈哈：

# 可视化打开浏览器

chrome_options = Options()
chrome_options.add_argument(f'--proxy-server={proxy.proxy}')
chrome_options.add_argument('--ignore-certificate-errors') # 忽略不安全证书提示
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.maximize_window()

# quit是退出浏览器
