运行google搜图会报httpx问题

[littleYaang]

感谢你们的杰出贡献，但我在使用cn/demo_google.py时会报如下错误：

但是其余的demo_x.py能够正常使用，网页也能够正常打开google网址。

你有检查用于配置代理的 proxies 变量吗？演示代码里的代理地址是本机的 1081 端口，这点从日志里也能看出来。

如果你的网络环境不需要代理，请将其设置为 None。否则，请将其更改为你正在使用的代理地址。

好吧，我弄错了。演示代码里的是 1080 。不过看样子还是网络环境问题，你换个节点试试？

根据这个 issue #126 ，可能是你所在网络的 DNS 出了问题，你更换后再试试吧。
