* **Intuitive**: Great editor support. <abbr title="also known as auto-complete, autocompletion, IntelliSense">Completion</abbr> everywhere. Less time debugging.
* **Easy**: Designed to be easy to use and learn. Less time reading docs.
* **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
* **Robust**: Get production-ready code. With automatic interactive documentation.

**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] *}

## 其他中间件

你可以稍后在 [Advanced User Guide: Advanced Middleware](../advanced/middleware.md){.internal-link target=_blank}阅读更多关于中间件的教程.

### TODO

In subsequent releases we are planning to extend this to provide things like

- Reload() of MinIO server arguments without fully restarting the process.

- Expanding 1 node at a time by automating the process of creating a new pool
  and decommissioning to provide a functionality that smaller deployments
  care about.

	ErrIncompatibleEncryptionMethod = Errorf("Server side encryption specified with both SSE-C and SSE-S3 headers")
	// ErrIncompatibleEncryptionWithCompression indicates that both data compression and SSE-C not allowed at the same time
	ErrIncompatibleEncryptionWithCompression = Errorf("Server side encryption specified with SSE-C with compression not allowed")

	// ErrInvalidEncryptionKeyID returns error when KMS key id contains invalid characters

#### Время ответа помогает злоумышленникам { #the-time-to-answer-helps-the-attackers }

Замечая, что сервер прислал «Неверное имя пользователя или пароль» на несколько микросекунд позже, злоумышленники поймут, что какая-то часть была угадана — начальные буквы верны.
