自动加载.env文件中的变量:只需在项目的根目录下创建一个.env文件,然后在代码中调用load_dotenv()函数,就可以自动加载.env文件中的所有变量。 手动管理环境变量:除了自动加载环境变量,Python-dotenv还提供了一系列函数(如set_key、unset_key、find_dotenv等),用于手动管理环境变量。
最後,在應用程式的啟動代碼中,使用 python-dotenv 庫從.env 檔案中讀取環境變數。 Python 複製 from dotenv import load_dotenv if ( os.environ['ENVIRONMENT'] == 'development'): print("Loading environment variables from .env file") load_dotenv(".env") 5:在應用程式中實作 DefaultAzureCredential ...
