polybar天气预报插件

自己手写一个，你可以直接抄作业。

获取天气预报api

首先需要自己注册一个api,我这里用的 openweathermap,注册账号后打开 https://home.openweathermap.org/api_keys,查看自己的 api_key
openweathermap 的api_key有延迟，界面显示可用的有时候好像需要半个多小时才可以使用，否则接口一直返回401错误
openweathermap 虽然有诸多不方便，比如英文，速度慢，但是天气预报很准确而且接口稳定，并分钟级实时预报，天气云图，国内很多免费的接口不稳定。

获取城市id

openweathermap 支持城市名称搜索查询，我这里为了简化直接用城市id了。打开openweathermap网站输入你所在地城市的拼音/英文名搜索，查看天气，地址栏的例如 https://openweathermap.org/city/1793724 1793724就是城市id了

手动测试api

访问地址： https://api.openweathermap.org/data/2.5/weather?id={城市ID}&appid={api_key}&units=Metric&lang=zh_cn 后面units是单位公制或者英制之类的 lang 就是语言了
正常应该可以返回json数据，如果是401错误，那么就是api_key错误，或者没生效，或者请求太频繁（1分钟上限60次）

本地准备

因为是polybar用，那么铁定是linux下日用，也肯定有pyhone了。我抄的别人的（原作者忘记）直接用了pyhone。
需要先引用requests, 没有安装。提前安装一下

sudo pacman -S python-pip
pip3 install requests
sudo pacman -Rns python-pip #是否卸载掉看你自己

创建脚本

把下面脚本的apt_key和城市id（1793724）换成你自己的

测试一下，正常可以在终端输出天气
