### Cache the OpenAPI schema { #cache-the-openapi-schema }

You can use the property `.openapi_schema` as a "cache", to store your generated schema.

That way, your application won't have to generate the schema every time a user opens your API docs.

It will be generated only once, and then the same cached schema will be used for the next requests.

  Getting to Plexus-configured Mojos

Abstract

  We're moving toward integrating mojos as first-class plexus components, while
  at the same time avoiding introducing required plexus dependencies into the
  mojo development model.

  In order to really achieve this, we need mojo configurations (which are

**FastAPI** 为了开发者方便提供了该对象. 但其实它直接来自于 Starlette.

### 在 `response` 的前和后

在任何*路径操作*收到`request`前,可以添加要和请求一起运行的代码.

也可以在*响应*生成但是返回之前添加代码.

例如你可以添加自定义请求头 `X-Process-Time` 包含以秒为单位的接收请求和生成响应的时间:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}
