最近有点无聊。第一次写.net版本的插件，可以显示当前城市的天气。apikey在高德可以免费申请。

你们把CAD玩坏了。有点不务正业了。

你有种再说一遍 · 发表于 2025-8-2 16:14:24

看来是个高手,都已经会异步了,
不过少了一个缓存层,当天应该不要重复去取.

效果什么样子的啊

，惭愧，用ai写的程序拼的。ai一步一步教出来的，刚刚知道怎么编译程序。

那你用AI的话,就需要继续追问了,
异步用不好的话会有奇特的效果.
例如Task就必须要await,
不然在独立进程下,启动后执行一半任务就死亡的线程.
任务即使完成了,但是由于没有设置信号机制,
导致它结束连接数据库失败而空转,出现隐藏bug,泄漏资源.

可以，虽然槽点太多了，这篇文章最有用的地方是，知道了高德可以申请免费api

直接显示在状态栏更好一些
