flask --help
Run Code Online (Sandbox Code Playgroud)
Run Code Online (Sandbox Code Playgroud)[...] Commands: db Perform database migrations. run Runs a development server. shell Runs a shell in the app context.
然后,如果您想列出给定命令的所有可用选项,例如run:
flask run --help
Run Code Online (Sandbox Code Playgroud)
Run Code Online (Sandbox Code Playgroud)Options: -h, --host TEXT The interface to bind to. -p, --port INTEGER The port to bind to. --reload / --no-reload Enable or disable the reloader.

因此,您可以将它们与文档示例中的模式一起使用,您只需在 ALLCAPS 中将名称和选项与下划线连接起来:
export FLASK_RUN_PORT=8000
export FLASK_RUN_HOST=0.0.0.0
Run Code Online (Sandbox Code Playgroud)
您还可以定义布尔选项:
export FLASK_RUN_RELOAD=True
export FLASK_RUN_RELOAD=False
Run Code Online (Sandbox Code Playgroud)
注意:flask --help将列出默认命令,但如果您在执行此帮助 ( export FLASK_APP=my_app.py)之前定义您的应用程序,您还将获得所有自定义命令。
