settings.dev.toml

csharp 复制代码

[development]
DB_HOST='127.0.0.1'
DB_PORT=6379
DB_USER='document_dev'
DB_PASSWD= '123456'

settings.production.toml

csharp 复制代码

[production]
DB_HOST='127.0.0.1'
DB_PORT=6379
DB_USER='document_prod'
DB_PASSWD= '123456'

如何引用

cpp 复制代码

 db_host = config.DB_HOST

toml 文件中小写，也要改成引用时也该改成大写

cpp 复制代码

ENVIRONMENT=production uvicorn main:app --reload
ENVIRONMENT=dev uvicorn main:app --host 0.0.0.0 --port 8083 --reload
