## Prerequisites

- Install and configure MinIO Server from [here](https://min.io/docs/minio/linux/index.html#procedure).
- Install and configure MinIO Client from [here](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart).

# MinIO FIPS Builds

MinIO creates FIPS builds using a patched version of the Go compiler (that uses BoringCrypto, from BoringSSL, which is [FIPS 140-2 validated](https://csrc.nist.gov/csrc/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp2964.pdf)) published by the Golang Team [here](https://github.com/golang/go/tree/dev.boringcrypto/misc/boring).

This directory contains JLine native libraries extracted from JLine JAR.

You can add your own build for platforms not natively supported by JLine.
See here [1] on how to compile for your platform and here [2] how libraries
follow JLine's directory and filename conventions.

接收到的错误信息清晰明了，HTTP 状态码为 `418`，JSON 内容如下：

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}

```

/// note | "技术细节"

`from starlette.requests import Request` 和 `from starlette.responses import JSONResponse` 也可以用于导入 `Request` 和 `JSONResponse`。

**FastAPI** 提供了与 `starlette.responses` 相同的 `fastapi.responses` 作为快捷方式，但大部分响应操作都可以直接从 Starlette 导入。同理，`Request` 也是如此。

/// tip

You'll see what other "things", apart from functions, can be used as dependencies in the next chapter.

///

Whenever a new request arrives, **FastAPI** will take care of:

* Calling your dependency ("dependable") function with the correct parameters.
* Get the result from your function.
* Assign that result to the parameter in your *path operation function*.

Você também pode usar `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.
