如何使用 ASGI 来部署

    Django’s management command sets up a default ASGI configuration for you, which you can tweak as needed for your project, and direct any ASGI-compliant application server to use.

    Django includes getting-started documentation for the following ASGI servers:

    Like WSGI, ASGI has you supply an application callable which the application server uses to communicate with your code. It’s commonly provided as an object named application in a Python module accessible to the server.

    It’s not used by the development server (runserver), but can be used by any ASGI server either in development or in production.

    ASGI servers usually take the path to the application callable as a string; for most Django projects, this will look like myproject.asgi:application.

    警告

    Do not call blocking synchronous functions or libraries in any async code. Django prevents you from doing this with the parts of Django that are not async-safe, but the same may not be true of third-party apps or Python libraries.

    When the ASGI server loads your application, Django needs to import the settings module — that’s where your entire application is defined.

    Django 利用 环境变量来定位合适的配置模块。它必须包含到配置模块的点式路径。开发环境和生产环境可以配置不同值；这都取决于你是如何组织配置的。

    To apply ASGI middleware, or to embed Django in another ASGI application, you can wrap Django’s application object in the file. For example:
