Appium Appium 切换多个 webview 如果切换到一个没有数据的页面， 再使用 driver.page_source 程序就一直卡着
场景
我现在有很多个 handle， 我也不知道要进入哪个 handle，只有进入后获取到 handle 的title 或者 page的内容 判断 才能确定我要切换的 handle
问题
首先有多个 handles ：[ 'CDwindow-74F23AC6F2E02CD49C80D105A59D9B88', 'CDwindow-E610CCBB026C5F2FA6C545A72D08344C', 'CDwindow-6FB6B9E476812C956796A6905BAFBE3A', 'CDwindow-B3DD449A8911B62F5C4F600EB4D345E2', 'CDwindow-A2D6E53D6E064CC9D5926F6E4971E9A1', 'CDwindow-0496AD7AB3EFB0BF1F7E27B6E57725A7']
如果切换的 handle 页面有数据的话代码是正常的 ， 如果第二个 handle 页面没有数据： 执行 driver.switch_to.window(CDwindow-E610CCBB026C5F2FA6C545A72D08344C) 是正常的，切换成功了，再获取page的时候，程序就卡住了， 如果是空页面，就拿不到page 或title
比如这样的就拿不到

找了一个临时的解决方法：
1、 获取当前的sessionId
2、 拼接 url
3、 请求 设置超时时间请求 url
4、 如果超时说明 handle 是无效的
灵感来源
session_id = self.driver.session_id
url = "http://127.0.0.1:4723/wd/hub/session/{0}/title".format(session_id)
try:
res = requests.get(url,timeout=3)
except:
dosomething
@Lihuazhang @seveniruby @chenhengjie123 @kasi @codeskyblue 请问有没有解决方案

问题就在于我也不知道 page 有没有内容， 最初是自己计算需要切换 handle，但有时候 handle list 加载就不规律，达不到预期。
