python和风api获取天气（JSON Web Token）

下载安装openssl

默认安装目录，添加C:\Program Files\OpenSSL-Win64\bin到用户Path环境变量

打开cmd，执行命令，会生成两个文件ed25519-private.pem，ed25519-public.pem

openssl genpkey -algorithm ED25519 -out ed25519-private.pem && openssl pkey -pubout -in ed25519-private.pem > ed25519-public.pem

和风控制台新建项目，创建凭据，上传公钥那里复制ed25519-public.pem的内容


点开项目查看凭据

右上角头像设置查看api host

官方模板代码
